Though it’s relatively rare in the US, food poisoning can happen to anyone, according to MedlinePlus. That doesn’t mean much if you’re the one who gets it. You may get food poisoning at home or while traveling. Each year 60-80 million (that’s MILLION) people around the globe get food poisoning.

If you’ve had food poisoning you know it’s awful, so awful you thought you were going to die. Some people do die. The FDA says food poisoning is especially threatening to kids five years old and younger, and the elderly. E.coli can cause hemolyptic uremic syndrome, which can lead to kidney damage and, in some cases, death.

The symptoms of food poisoning are nasty: nausea, vomiting, diarrhea, fever, headaches, and weakness. Food poisoning strikes within two-to-four hours after eating contaminated food and it can last as long as 10 days. Prevetion is the best defense against food poisoning.

Mayo Clinic, in an Internet article called “Serve it Up Safe: 8 Ways to Prevent Food-Bourne Illness,” lists some prevention tips, such as washing linens often and washing equipment, including your meat thermometer, in hot, soapy water. To be in the safe side, the article says you should reheat leftovers to an internal temperature of 165 degrees.

Practice safe food handling during the holidays. Unsure about what to do? The USDA Food and Safety Inspection Service has published a colorful booklet called “Cooking for Groups.” You’ll find the booklet on www.FoodSafety.gov. You’ll find additional information on www.fightingbac.org. And follow these tips to keep your tummy safe during the holidays.

AT HOME

1. Wash your hands well before handling food.

2. Use paper or cloth dishcloths, not sponges.

4. Separate raw foods from ready-to-eat foods.

5. Store washed produce in a different container, not the original.

6. Keep cold foods at 40 degrees or less.

7. Keep hot foods at 140 degrees or more.

8. Double-bag leaking meat and poultry packages or seal them in plastic wrap.

9. Thaw meat and poultry in the refrigerator, not on the counter.

10. NEVER eat frozen meat, poultry or fish that has been thawed and refrozen.

11. Check internal temperature of meat and poultry with a thermometer.

12. Use a clean spoon every time you taste food.

13. Clear leftover food quickly and refrigerate.

AT WORK

1. Ask a knowledgable person to be in charge.

2. Refrigerate donated food immediately.

3. Wash hands before handling food. (Buy several bottles of hand sanitizer.)

4. Label foods so people know what they’re eating.

5. Tell people if food contains nuts or soy.

6. Serve food in small batches, not all at once.

7. Keep mayonnaise-based foods icy cold.

8. Keep hot foods really hot.

9. Don’t leave food out for more than two hours.

10. Provide clean storage containers for leftovers. Write the food and date on all containers.

11. Discard food that hasn’t been refrigerated for more than four hours.

AT A RESTAURANT

1. Check to see if food handlers are wearing plastic gloves.

2. Find out if the food handlers are handling money. (Money is often contaiminaed with human feces.)

3. Is there a cough shield over the food table?

4. Skip the salad bar if the ingredients aren’t on ice.

5. Check to see if the restaurant has a clean plate policy for additional servings of salad.

6. Don’t eat salad dressing that’s in open bowls on the table.

7. Make sure hot food is kept in warming pans, kettles, and hot plates.

8. Each dish should have its own serving spoon or fork.

9. Servers should bring buffet foods out in small batches.

10. Does the menu say all beef will be cooked to medium temperature?

11. Hamburgers should be cooked until the internal temperature is 160 degrees.

12. Write the food and date on your doggie bag/box.

“Everyone is at risk for foodbourne illness,” according to the FDA’s Food Safety Education Website. That makes food safety your business. Call the local public health department if you see unsafe food practices. And follow the FDA’s advice during the holidays: When in doubt throw it out!

To say that encountering this complaint would spoil your whole day would be a gross understatement. In fact you’re likely to spend several days recovering from it. In extreme cases it can be fatal.

So is there any way to make sure you never succumb to food poisoning? Well, there may be no infallible approach, but you can certainly act in such a way that your chances of becoming a victim are drastically reduced.

Personal hygiene is a good starting point. This question is perhaps a trifle taboo, but I’m going to ask it anyway – do YOU wash your hands after going to the toilet? If you don’t, you will after reading this. This is to me the most basic and essential step in keeping even a reasonable level of personal cleanliness. Yet so many people neglect to do this. To me, that’s just asking for trouble sooner or later, and is in any event a betrayal of everyone else you come into contact with.

Who do you think really wants to share with you the myriad of germs and microbes that you have on your hands immediately after attending to the bodily functions that we all have to attend to several times a day? And you will share them with everyone who touches almost anything fairly soon after you’ve touched it, or with whom you shake hands. It’s the reason why most PC keyboards are as rife with germs as a toilet seat.

I still see people coming out of public lavatories without so much as a glance at the wash basins. Yet they’ve been in a place rife with both air borne and surface bound germs and microbes. The very smell of them broadcasts their nature. Until such people actually DO wash their hands everything they touch will be contaminated with the harmful bacteria and shigella that is without doubt increasing and multiplying on their hands.

For this reason I always wash my hands carefully every time I return home from a trip out, even if I’ve only been to the corner shop. It makes sense, doesn’t it?

If all the doctors and nurses, patients and visitors, hospital workers and porters and everyone else to be found in hospitals simply washed their hands after doing what we all have to do a few times a day, then all the so-called hospital super-bugs, the MRSA and everything else that we spend millions of pounds or dollars trying to fight each year, all of it would simply disappear.

However, don’t hold your breath waiting for that to happen.

Always make a point of washing your hands thoroughly before preparing food. If the ingredients of the meal include meat, fish, fowl or eggs then wash after each time you’ve handled them.

The next point is to never eat raw food that comprises meat, fish, fowl, milk or eggs. Sea food is especially prone to harbour harmful bacteria, so be particularly careful when eating this. Wash all food under the cold tap before cooking or eating.

Above 65.5 or below 4.5. Those are the figures to remember concerning the temperatures in degrees Celsius or Centigrade in which bacteria cannot multiply. That’s why raw food has to be kept chilled until it is ready for cooking, when it should be heated to at least the temperature required to kill bacteria.

To be sure of this, meat should be cooked until there is no more pink left in it, fowl until none of the joints are red and fish should be flaking by the time it’s taken out of the oven.

If using a microwave oven you should use a meat thermometer to check the internal temperature. Keep meat gravy or juice away from other food. Use separate utensils, chopping board, etc for meat and other animal products on the one hand and everything else on the other. Wash them with bleach or lathered water afterwards. In fact wash the whole kitchen work top area regularly and always after preparing dishes containing animal products. Replace sponges regularly and use paper kitchen towels for wiping down.

Food that’s been left at room temperature for 2 hours or more can be contaminated, especially if it is high in protein, eg meat, eggs, chips.

Be careful when defrosting meat or poultry, as the surface will defreeze more quickly than the inside. Bacteria may therefore be growing on the outside by the time the inside is unfrozen. Defreeze it in the refrigerator to avoid this problem. If keeping anything for another meal, replace it in the refrigerator immediately. And never keep meat or poultry, or fish, above vegetables or other kinds of non-meat food in the refrigerator in case anything falls down to cause contamination.

Trust your instincts. If food doesn’t somehow look right then it usually isn’t. A quick test with your nose should detect any tell-tale smell of decay or contamination.

Finally, eat your food slowly, relish it and allow your body and digestive system ample time and optimum conditions for digesting it. Bon appetit!

First of all, relax… making baby food is simple. You don’t need many ingredients, special equipment (except a blender or food processor) or much time.

Apart from saving you money, making your own baby food provides fantastic nutrition for your little one and gives you peace of mind. After all you know exactly what’s gone into your baby’s food, how it was prepared and the quality of ingredients used.

Most pediatricians advice babies should be be between 4 and 6 months before starting solids. Rice cereal is usually the first food of choice as it doesn’t contain wheat (which can be harder for babies to digest) and most babies can easily tolerate it.
If you’re not sure if your baby is ready for solids always ask your pediatrician first.

It’s always best to introduce one new food at a time just in case your baby has an allergic reaction to a certain food. This will make it easier to pinpoint which foods caused it.

Here’s an easy step-by-step guide to making baby food.

Hygiene:

There’s no need to sterilize feeding equipment as you would baby bottles and teats, but you should wash everything you’ll be using in hot soapy water before starting. It’s also smart to wipe down the counter top and work area before starting.

As with regular cooking, it’s important to use a separate chopping board for meat to avoid cross contamination. And do not let raw food come into contact with cooked food.

Always thaw frozen baby food in the refrigerator. Thawing the food at room temperature may breed bacteria which can cause illness.

Equipment:

A food processor, blender or hand-held blender is ideal for a very smooth consistency. Once your baby is used to solids you can simply mash the food with a fork.

Preferably your baby should sit in a high chair or other upright child safety seat. Baby should be upright at all times to help food digestion and avoid choking.

To feed baby a few simple plastic bowls and spoons without rough edges will do. And don’t forget to get a few packs of baby bibs and have plenty of cleaning cloths handy!

Preparation:

Scrub and peel fruits and vegetables well.

Remove all fat, skin, and bones from fresh meat. Always check to make sure the meat is fresh. If you have any doubts as to the freshness of the meat, it’s best not to use it as it’s just not worth your baby getting sick.

Use only a small amount of water when cooking to avoid loosing valuable nutrients. Many vegetables can be steamed to preserve nutrients.

Never add any seasonings, salt, sugar, or other sweeteners. This will make the food too strong for your baby’s taste buds and can actually make him ill.

Transfer cooked food to a food processor and process until smooth (adding a little of the cooking water if necessary) or use a hand-held blender.

For a thicker consistency, simply mash the food using a fork. You can always add a little breast milk or formula to make it smoother.

* Medical literature advices egg whites, strawberries, honey and peanut products should be avoided until 12 months of age as they have been known to cause allergies in young children.

Storage:

As baby’s only eat a small amount of food, freezing is ideal for baby food. There are several ways you can do this.

One of the easiest ways is to fill up an ice cube tray with any unused baby food (do not save any leftover food from your baby’s bowl or that has been contaminated by your baby’s saliva). Once the food is frozen immediately transfer to individual plastic bags. Depending on how much your baby eats, place a few cubes of baby food in each bag. Don’t forget to label and date it.

Advice varies on how long you should freeze baby food for. Most experts agree frozen baby food should not be kept longer than 3 months. Ideally, try not to keep the food longer than one month as it may loose some of its nutritional content as time passes. Remember your baby doesn’t eat very much at first so make smaller batches.

You can also place small amounts of food in individual plastic containers with lids, and stick labelling tape to the top of the lid.

Reheating:

Easily reheat frozen food by placing it in a heat-proof bowl. Place the bowl in or over a pan of simmering water. Gently reheat while stirring occasionally.

You can also reheat the food in the microwave. This will save you time, but be extra careful as the food will be hotter in some places more than others. Always stir the food and taste it before serving to make sure it’s not too hot. Always, let the food sit for a minute or two before serving to baby. Stir again just before serving.

Always thaw frozen baby food in the refrigerator. Do not thaw baby food at room temperate as it can breed bacteria.

That’s it… a few simple steps to making your own baby food. Homemade baby food will save you money but best of all you’ll be giving your baby the most nutritious foods possible.

Food spoilage is really nothing more than a natural deterioration of organic matter. Everything in nature has to be broken down so that it can once again become part of the composition of soil. All of the various natural processes that participate in the spoilage of organic material are ultimately directed toward this aim.

Odor. Bad odor is a symptom of food spoilage. Foods that have a bad odor should be thrown out. We have already gone into the causes of foul refrigerator odor with regards the spilage of food. Yet there is another factor that we should take into consideration when talking about foul odors of food and that is that the odors can be soaked up by foods which have not spoiled and make them disagreeable to eat. In saying that, this problem does not only pertain to food which has spoiled. Nobody would like to eat a piece of cake that has adopted the odor and taste of smoked salmon, for instance. This is a major problem in the home kitchen. Luckily there are now products available that help to reduce the severity of refrigerator odor and foul taste transfer between foods. Now you can buy a refrigerator purifier that will prove invaluable in the prevention of refrigerator odor. This product is a real food saver. Small air filters for fridges are also available.

When we define food spoilage we can say that spoilage of food pertains any disagreeable change in the nature of food from the normal condition that we expect. These changes may compromise food hygiene. We are able to distinguish these changes through use of our senses. For instance, food may change visually, it may change in smell, to the touch or in taste. In saying that, we use some forms of what technically amounts to food spoilage, in a controlled way, to achieve a desired effect, as in Camembert cheese for instance. We crave the runiness of the cheese that is produced by specially selected bacteria and mould to produce an effect which many of us find pleasing to eat. Other examples of controlled food deterioration include Danish blue, Gorgonzola, Stilton and many other forms of cheese. We also tenderize meat such as game by jugging it or purposely speed up the deterioration process of meat when we inject lactbacillus bacteria into steak to mimic the ageing process. In short and in technical terms, food spoilage works for us easily as much as it works against us.

Nevertheless, food does spoil because once the fruit of vegetable has been picked or the animal has been slaughtered, the natural processes and defences of the organism are compromised and exposure to the outside environment causes a number of inevitable changes to occur.

The factors which bring about these changes include, air and oxygen, light, moisture, microbial growth factors and ambient temperature. Some of these changes indicate poor food hygiene and cross contamination and others point to chemical reactions and changes due to physical phenomina. Let’s go through the various causes.

Air and oxygen: Air comprises of about eighty percent nitrogen and about twenty percent oxygen. The level of oxygen in the air is too great for most organisms and therefore organisms have developed strategies to counter the harmful effects of oxygen. Our lungs are lined with a substance called surfactant. Surfactant provides a necessary barrier between the tissue of the lung and the oxygen in the air to counteract the caustic effect of the oxygen upon the lung tissue. Our bodies and the bodies of other organisms produce anti oxidants to counter other undesirable reactions of oxygen with substances called free radicals. By binding to free radicals, anti oxidants prevent reactions which are harmful to our bodies. When an organisms no longer has the support of it’s various physiological support systems, the chemical make up of the organism will start to react with the oxygen in the air.

Micro organisms which require the presence of oxygen in order to metabolize organic tissue, such as aerobic bacteria and moulds, are able to colonize those areas of the flesh which are exposed to the air. The will form colonies upon the food and start to metabolize the flesh of the organism and divide at a rate of one division every twenty minutes per bacterial cell. In some cases as few as one thousand bacteria can be enough to contitute a food hygiene risk.

Enzymes, particularly oxidizing enzymes, which react with oxygen also aid the process of food spoilage. In vegetables enzymes such as catase and peroxidase cause the familiar browning of the flesh of foods such as apples and potatoes. Enzymes are substances which speed up chemical reactions and enzymatic reaction with oxygen in organic matter causes the degeneration of the matter to hasten considerably. In cooking a rapid heat treatment known as blanching is used to cancel these enzymatic reactions. Enzymatic changes do not usually render food inedible but if combined with microbial infestation such as mould or certain bacteria the ingestion of such spoiled food would constitute a food hygiene risk.

Water: water is the most abundant substance in nature. All organisms are made up of at least seventy percent water. The water within an organism when it is alive is termed as bound water because it is chemically connected to other substances within the body. All living organisms maintain a certain level of chemical concentration. This is said to mimic the concentration of sea water from which all living organisms originate. Concentrated fluids flow around the cells and each cell contains within it a carefully controlled liquid environment. The balance between the concentration of the fluids which flow around the cell and the fluid which exists within the cell is carefully regulated by the central control system of the organism, whether it be plant or animal. In higher organisms this process is called homeostasis.

Once a plant or an animal has been cut into smaller parts, the tissues whose fluid environment was once carefully controlled are now exposed to the environment. When the organism’s flesh comes into contact with moisture a physical phenomenon occurs. All substances in nature try to match their concentration levels to other substances around them, This is called diffusion. The flesh of an organism, when exposed to water will soak up the water in an attempt to dilute the concentration levels within the flesh of the organism to the concentration levels around it. This may cause the cells of the organism to explode by being too full of water. This form of tissue deterioration is a major cause of food spoilage. This intake of moisture into the tissue of the food source is the perfect vector for micro organisms to infest it. This is a very good example of how food spoilage occurs and food hygiene breakdowns happen.

In addition, excess “free” water within or around the cell gives bacteria the perfect medium in which to operate. In bacterial terms this is like a super highway in which bacteria are able to spread throughout the flesh of an organism. Water within an organism can be controlled by a) dehydration, b) freezing or c by the addition of food preservatives.

Light: Spoilage of food which is caused by light is called photo degeneration. All food is exposed to light at some time or another. Light can be either natural light or artificial light. Light, like all other forms of energy is made up of different wave lenghts. At the outer ends of the light spectrum we have infra red and ultra violet light which can vary in intensity in different parts of the world. These forms of light radiation are known to be harmful and can cause dead and live tissue to react in negative ways.

Exposure to light sources can cause foods to change in nature. Pigments may change, as may vitamin levels, fats and proteins. In solid foods the density of the material such as in meat may block deep penetration of light and therefore the effects of light may only cause changes to happen on the surface of the product. In liquids light penetration can be much deeper and therefore the effects of photo degeneration can be much more substantial.

Microbial growth. Micro organisms play a vital role in the balance of nature. Bacteria and other types of microbes haves each evolved to fill a specific niche. Some bacteria have developed a symbiotic relationship relationship with living organisms and some have developed a parasitical relationship. Healthy organisms manage to keep parasitical bacteria at bay through their immune systems and homeostasis. However, parasitical bacteria are constantly on the look out for signs of weakness and it is their job to bring about the rapid demise of sick organisms and to ensure that they are re cycled back into the environment through the process of tissue deterioration and degeneration. In prehistoric times man did not store much food. He ate from hand to mouth and so food did not have much time to go off. Modern man, because of his lifestyle, needs to store food and to do this he needs to effect a different kind of environmental control in comparison to prehistoric man.

In a previous chapter I mentioned that psicrophilic bacteria can cause food spoilage at low temperatures. In cold climates landscapes freeze for many months and animals find it difficult to survive. Weaker animals die during the winter months and remain frozen until the beginning of the thaw in spring. Although thawed a carcass may remain too cold for many types of bacteria to develop and it is for this reason that certain bacteria adapted to this niche so that the detioration of the carcass could begin. This process helps to ensure that the period of time during which more pathogenic bacteria infest the carcass and hence spread into the environment is considerably lessened. This is the function and importance of psicrophilic bacteria in nature. We can control the undesirable effects of psicrophilic bacteria in our cold stores through the implementation of a good hygiene regime.

In general, sources of food contamination come from the environment particularly from, animal wastes, soil, water and air. Here the “Four stages of food hygiene” come into play. Great care must be taken to make sure that food comes from safe sources, that food does not come into contact with other bacterial sources, that bacteria does not have conditions for growth and that tools and work surfaces are kept free from bacteria. food hygiene regime and temperature is all critical here. Don’t make mistakes or cut corners and bacteria will not develop.

Temperature. Temperature is probably the single most important environment which we can control to prevent the spoilage of food. Temperature regulates several changes in the nature of organic matter. Firstly it slows down chemical reactions within the food. Secondly it can prevent the ggrowth development of bacteria or destroy bacteria through cooking, Temperature regulation can control the destruction of vitamins and prevent dehydration and ripening of food.

However, temperature need to be professionally controlled. Over freezing can cause surfaces to crack of the development of ice crystals at microscopic levels can puncture cells causing the flesh to become soft and pulpy. Pigment can be lost and chemicals within the food may react and loose much of their nutritious value. This process is commonly called freezer burning.

In cold stores vegetables and fruit are best held at temperatures of around 10 degrees Celsius. meats should be chilled to four degrees Celsius and frozen food should be stored at -18 degrees Celsius for a period not exceeding six months in most cases. Aaways make sure that you follow manufacturers storage instructions. If in doubt don’t be afraid to contact the manufacturer or importer to get their advise.

What is listeriosis?
Listeriosis is a bacterial infection caused by the bacterium Listeria monocytogenes. Until several years ago it was thought that this bacteria only infected animals but it is now accepted that humans are also at risk from this disease. While many bacteria are generally seen to infect specific locations within the human body, Listeria may infect many different locations, such as the brain or the spinal cord membranes or the bloodstream.

Classification:
L. monocytogenes is a gram positive, non-spore forming, motile, facultatively anaerobic, rod shaped bacterium. It is catalase positive, oxidase negative, and expresses a Beta hemolysin which causes destruction of red blood cells. This bacterium exhibits characteristic tumbling motility when viewed with light microscopy. [6] Although L. monocytogenes is actively motile by means of peritrichous flagella at room temperature (20-25C), the organism does not synthesize flagella at body temperatures (37C). [7]

Who gets listeriosis?
Anyone can get this disease, but those at highest risk for serious illness from this bacterium are newborns, the elderly, people with weakened immune systems, and pregnant women. Healthy adults and children occasionally get infected with Listeria, but they rarely become seriously ill. Listeria Monocytogenes is classified as an intracellular paracite. This means that it invades and lives within cells of the body thereby managing to evade the body’s immune system. Infection by as few as 1000 individual bacteria is considered enough for the disease to take hold. When listeric meningitis occurs, the overall mortality may reach 70%; from septicemia 50%, from perinatal/neonatal infections greater than 80%. In infections during pregnancy, the mother usually survives.

When do Listeria infections occur?
Infections occur throughout the year. Although most cases occur sporadically, food-borne outbreaks of this disease do frequently occur. Poor food hygiene and poor personal hygiene conditions are responsible for many of the recently recorded outbrakes.

How is listeriosis spread?
Listeria bacteria are widely distributed in nature and can be found both in water and soil. Infected animals may also serve as sources of contamination. Unlike other organisms, Listeria can be spread through several different methods. Ingestion or food-borne transmission of the organism, such as through the ingestion of unpasteurized milk or by the eating of contaminated vegetables, is often a source of many cases. In newborn infections, the organism can be transmitted from mother to fetus in utero, or directly to the fetus at the time of birth through the contact of the fetus’ blood supply with that of the mothers. Direct contact with the organism can cause lesions on the skin.

What are the symptoms of listeriosis?
Because listeriosis can affect many different parts of the body, the symptoms vary. For meningoencephalitis, the onset can be sudden with fever, intense headache, nausea, vomiting and signs of meningeal irritation. In other body locations, various types of lesions at the site of infection are the primary symptom. In most cases, Listeria infection causes fever and influenza-like symptoms resembling a host of other illnesses.

How soon after exposure do symptoms of listeriosis appear?
Listeriosis has an extremely variable incubation period. It can range from 3 to seventy days, but symptoms usually will typically appear within a month of infection.

How is listeriosis diagnosed?
Specific laboratory tests are the only way to effectively identify this disease. Since many cases may be mild, the disease may be much more common than is realized.

Are there any unusual features of listeriosis?
Listeria infections are a significant risk for pregnant women, who may not experience obvious symptoms. Infection of the fetus can occur before delivery and can cause abortion as early as the second month of pregnancy, but more often in the fifth and six months. An infection later in pregnancy may cause exposure during birth, sometimes resulting in infection of the newborn child which may be fatal.

Does past infection with Listeria make a person immune?
Past infection does not appear to produce immunity.

What is the treatment for Listeria infection?
Several antibiotics are effective against this organism. Ampicillin, either on it’s own or in combination with other types of antibiotics, is frequently used.

What can be done to prevent the spread of Listeriosis?
Since the organism is widly distributed throughout nature, basic sanitary measures such as only using pasteurized dairy products, by only eating cooked meats and washing hands thoroughly prior to the preparation of foods offer the best protection against infection by this disease.

In addition, the following recommendations are for persons who are categorized to be at high risk of infection, such as pregnant women, the elderly and persons with compromised immune systems:

Do not eat hot dogs, luncheon meats, or deli meats, unless they are reheated until they are steaming hot.
Avoid getting the liquid from hot dog packages onto other foods sources, utensils, and food preparation surfaces, and remember to wash hands after handling hot dogs, luncheon meats, and deli meats.
Do not eat soft cheese products such as feta, Brie, and Camembert, blue-veined cheeses, or Mexican-style cheeses such as queso blanco, queso fresco, and Panela, unless they clearly state they are made from pasteurized milk written on the labelling of the product.
Do not eat chilled pâtés or meat spreads. Canned or shelf-stable pâtés and meat spreads can be eaten.
Do not eat refrigerated smoked seafood, unless it is contained in a cooked dish, such as a casserole. Refrigerated smoked seafood, such as salmon, trout, whitefish, cod, tuna or mackerel, is most often labeled as “nova-style,” “lox,” “kippered,” “smoked,” or “jerky.” The fish is found in the refrigerator section or sold over deli counters of grocery stores and delicatessens and supermarkets. Canned or shelf-stable smoked seafood may be eaten.

Campylobacter is one of the most common bacterial causes of gastro intestinal diarrheal sickness in the United States of America. The vast majority of these cases occur as isolated and sporadic events and not as part of recognized epidemic like outbreaks. Ongoing surveillance by FoodNet demonstrates that about thirteen cases are diagnosed each year for each 100,000 persons in the population. Many more cases go undiagnosed or unreported, and campylobacteriosis is estimated to affect more than 2.4 million persons each year, or 0.8% of the total population of the USA. This disease is also very common in Europe, the Middle East and Asia. Campylobacteriosis occurs far more frequently in the summer months than in the winter months. The organism is isolated from infants and young adults more frequently than from persons in other age groups and from males more frequently than females. Although Campylobacter does not commonly cause death, it has been estimated that approximately 124 persons with Campylobacter infections die each year in the USA.

Campylobacter organisms are spiral-shaped bacteria that can cause disease in humans and animals. Most human illness is caused by one species, called Campylobacter jejuni, but human illness can also be caused by other species. Campylobacter jejuni grows best at the body temperature of a bird, and seems to be well adapted to birds, who carry it without becoming ill. These bacteria are fragile. They cannot tolerate drying and can be killed by oxygen. They grow only in places with less oxygen than the amount in the atmosphere. Freezing reduces the number of Campylobacter bacteria on raw meat.

Almost all persons infected with Campylobacter recover without any specific treatment. Patients should drink extra fluids as long as the diarrhea lasts. In more severe cases, antibiotics such as erythromycin or a fluoroquinolone can be used, and can shorten the duration of symptoms if given early in the illness. Your doctor will decide whether antibiotics are necessary.

Most people who get campylobacteriosis make a complete recovery within two to five days after the onset of symptoms, although sometimes in more serious cases recovery can take up to 10 days. Rarely, Campylobacter infection results in long-term consequences. Some people may develop arthritis. Others may develop a rare disease called Guillain-Barré syndrome that affects the nerves of the body which begins several weeks after the onset diarrheal illness. This occurs when a person’s immune system is triggered to attack the body’s own nerves which results in temporary paralysis that lasts several weeks and usually requires an intensive care regime. It is estimated that approximately one in every 1,000 reported Campylobacter illnesses leads to Guillain-Barré syndrome. As many as 40% of Guillain-Barré syndrome cases in this country may be triggered by campylobacteriosis.Campylobacteriosis usually occurs in single, sporadic cases, but it can also occur in outbreaks, when a number of people become ill at one time. Most cases of campylobacteriosis are associated with eating raw or undercooked poultry meat or from cross-contamination of other foods by these poultry items. Infants may get the infection by contact with poultry meat wrappings in shopping carts. Outbreaks of Campylobacter are usually associated with unpasteurized milk or contaminated water. Animals can also be infected, and some people have acquired their infection from contact with the stool of infected dogs or cats. The organism is not usually spread from one person to another, but this can happen if the infected person is producing large volumes of diarrhea and/or vomit. A very small number of Campylobacter organisms (fewer than 500) can cause illness in humans. Even one drop of juice from raw chicken meat can infect a person. One way to become infected is to cut poultry meat on a chopping board, and then use the unwashed chopping board and knife or other utensils which came into contact with the raw meat to prepare vegetables or other raw or lightly cooked foods. The Campylobacter organisms from the raw meat can by these means spread to the other food products.

Many chicken flocks are infected with Campylobacter but may very well show no signs of illness. Campylobacter can be easily passed from bird to bird through a common water source or through contact with infected feces of other birds. When an infected bird is slaughtered, Campylobacter organisms can be transferred from the intestines to the meat. Likewise, the bacteria can infect a whole batch of birds via the presence of the bacteria being present on equipment and on the hands and/or the gloves of the slaughter house workers who do not wash hands between each bird they handle. In 2005, Campylobacter was present on 47% of raw chicken breasts tested through the FDA-NARMS Retail Food program. Campylobacter is also present in the giblets, especially the liver.

Unpasteurized milk can become contaminated if the cow has an infection with Campylobacter in her udder or milk which has been contaminated with manure. Surface water and mountain streams can become contaminated from infected feces from cows or wild birds. This infection is common in the developing world, and travelers to foreign countries are also at risk for becoming infected with Campylobacter.

I was asked to help solve a problem concerning cross contamination and product quality control in one of the smaller fruit juice factories in our area yesterday. The factory in question has a capacity to produce 72,000 liters of various fruit juices, fruit drinks and fruit nectar and ice teas. The factory basically consists of two departments, a mixing department and a bottling department. The products are either packed in glass bottles, plastic bottles or tetra pak cartons.

All of the concentrates are poured into the 18,000 liter vats via a barrel tipping machine and a suction device for roto plasts. The concentrates are pumped through a pipe console which directs the concentrates in to one of four vats in the mixing department.

The factory had started producing tomato juice several months ago and since the onset of this production the company has been experiencing problems with the shelf life and color of products. They had tried every way they could imagine to clean the pipes leading into the tanks but to no avail. Tomato paste is very thick and viscose which makes it a difficult product to work with. Tomato paste tends to travel through pipes in pulses and because of this it coats the pipes evenly from the inside. Thinner and less solid substances such as caustic soda solution tends to run along the bottom of pipes and will only reach the top extremities for brief moments. This makes cleaning tomato paste particularly problematic.

I could smell the presence of tomato concentrate coming out of all of the pipes. There was no question that there was a grave danger of the tomato residue in the pipes fermenting. After a little thought this was my solution to the problem:

1) only to use two of the tanks for producing tomato paste. The effect this would have would be to reduce any possible risk by 50% from the outset.

2) to install separate feed pipes into those two tanks for tomato paste. This would leave the pipes for other products uncontaminated by tomato paste.

3) To dilute the tomato paste with 50% chilled water in a 500 liter mixing tank which was already on site.(2 degrees centigrade) prior to being pumped into the tanks. This would cause the concentrate to be less viscose and much easier to clean during the CIP process.

4)To dissemble and to clean the pump on the barrel tipping machine after every use.

5) To dissemble all pipes weekly and to immerse them in caustic soda solution.

6) To clean all pneumatic valves with a special industrial pipe cleaning brush from all directions.

At the end of the meeting with the department head, production manager, head of quality control and the general manager, all my suggestions were accepted and will be implemented within one working week. I will conduct a follow up check one month from today.

Last Monday morning I received a phone call from the area superintendent of the department of public health. She told me that there was a steady stream of people falling sick due to eating food prepared by one of the large kitchens in our area. She continued to tell me that her department had been through the place with a fine tooth comb but still couldn’t find the source of the contamination. I arranged to meet them at the premises in question the following day to conduct an inspection.

To tell you the truth, I had a pretty good idea what I would be looking for because I had been to that particular kitchen several times in the past and had spotted a few things that seemed problematic. However, I had to make it seem as if I was earning my money so I decided that we would start somewhere quite far from the place that I suspected to be the problem.

We started by taking swabs of everything we saw and asked staff to provide swabs, blood, urine and stool samples. We checked the toilets of staff and diners alike and took swabs from all manner of cooking pots and trays,

I knew that this kitchen was using a type of bread basket within which to thaw meats and fish. The bread baskets were stacked one upon the other and left inside the two degree Celsius anti room of the freezer complex for up to four days. I also knew that the baskets were loaded onto a low level service trolley and brought up to the kitchen. I had known the chef of this kitchen for a number of years and I also knew that it was his practice to unload the baskets into plastic tubs after the lunch had gone out to the dining room. I always made a practice of doing this first thing in the morning before we started on the days chores.

What this meant was that the contents of the baskets were left to warm up from between seven o’clock in the morning until 11 o’clock in the morning. This wasn’t a very good practice. Every chef has his ways but I knew that this was not the exact point I wanted to look at closely. What bothered me were the baskets themselves. I had a word with the chef and asked him to make an exception today and vacate the baskets earlier. What i notices was what I suspected. After rinsing the basket with water to remove the blood I saw that there was a light colored plaque stuck to the plastic. I took a scraper and saw that it came away fairly easily. I took scrapings from all the baskets used that day and then took the baskets to the aluminium washing machine to see what happened.

The man working on the machine proudly took a stack of five baskets and but them onto the machine and presses the operating handle down. The baskets disappeared into the machine for a few seconds and then came out. The worker informed me that this was a very efficient way of washing the baskets. he then placed them back onto the service trolley which had not been washed only sprayed with a water gun and placed the baskets next to the lift ready to by taken back down to the freezers.

The guy in charge of the freezer units the proceeded to re fill them with produce for another day. I had noticed several things, 1) the baskets had not been scrubbed with a stiff plastic brush of Brillo pad with detergent, 2) they had only been rinsed inside the machine which used high pressure but was ineffective due to the fact that the stacking of baskets inside the machine rendered the high pressure ineffective,3) chicken, beef, pork and fish had been set out to thaw in the same tower of eight baskets.

All of this led us to believe that we had quite possibly found the missing link of the food contamination dilemma. What had been happening was that liquid released from the thawing meat and fish had been dripping onto the plaque in the bottom of the baskets which in turn had been dripping onto the neat inside the baskets below. Then we discovered something else. The worker who had been handling the baskets went to work on the dish washing machine that cleaned the crockery and cutlery merely wiping his hands on a towel and removing his plastic apron before going onto the dish washing machine. It was his job to remove the clean cutlery off the dish washing machine. We clearly saw that he could be contaminating the cutlery.

All we needed to do now was to take the cultures we had taken back to the lab and have them checked out. These were the findings. Camphilobacter, Staph Aureus, Salmonella, e. coli, vibrio an listeria were all present in large quantities within the plaque which we removed from the bread baskets. Our findings were relayed to the company management with the following recommendations. All bread baskets to receive immediate soaking in caustic soda. 2) All bread baskets to be scrubbed individually before putting them onto the aluminium machine,3) all bread baskets to be put into the aluminium machine individually and 4) all bread baskets to receive a weekly soaking in caustic soda. 4) aluminium machine worker was to thoroughly wash his hands and change overalls before helping out anywhere else.

A re check will be conducted in two weeks from the day all the baskets were washed in caustic soda.

A new Hampshire camp was close while it was being checked for the cause of salmonella food poisoning. Children fell sick after eating a pudding that was contaminated with pathogenic salmonella bacteria. After all the negative publicity about salmonella in the media over the past couple of weeks, another salmonella outbreak was the last thing this well renowned camp needed.

Puddings and other deserts are quite common vectors of salmonella poisoning for several reasons. I would like to go over some of these reasons in this article to give you insight into the world of puddings and deserts.

Last courses are very often very minimally cooked. Sometimes they incorporate meringue which is basically just egg white beaten with sugar. Often last courses are not cooked to temperatures that exceed the boiling point of milk which is around 80 degrees Celsius. Some strains of resistant and virulent bacteria are very capable of withstanding such temperatures.

Camps are places which function only at certain times of the year and infrastructure of camp kitchens is not very sophisticated. Fridges may not function at required temperatures and food stores may be open to many different persons from within the camp. In addition, the staff which are hired by camps to do kitchen work might not be state of the art professionals, particularly in matters of food hygiene. If that were not enough and to cut staffing costs still further camp cooks are requested by management to work with casual workers who may have little if not no prior knowledge about the workings of a large kitchen.

Chefs are known to like to mix many ingredients by hand, particularly when using corn starch. Corn starch likes to coagulate when it comes into contact with liquid and many chefs like to feel that the consistency of a mixture is smooth. If the chef or one of his workers has not washed his hands properly after going to the toilet or after handling meat or fish (particularly chicken or turkey), bacteria will infest the desert mixture.

Another possibility for salmonella contamination is if the chef or one of his helpers failed to notice that eggs, milk of both used in the mixture for a pudding were not fit to be used. Often casual staff do not know the signs of contaminated milk or eggs.

Yet another possibility is that the chef made a pudding mixture early in the morning before he started to prepare meats and other foods that may contaminate a pudding mixture but failed to insure that it was refrigerated. On discovering the mistake he may have decided to take the chance that the mixture was not contaminated. These things do happen in many, many kitchens.

Another scenario could have been that staff cut corners and failed to wash cooking trays properly after a previous usage. These dirty dishes may have been exposed to cockroaches rats,cats or racoons and thus contained with salmonella. The final possibility that I would like to mention is that one or more of the ingredients other than eggs and milk that went into the pudding may have been infected with salmonella. After all, salmonella has been turning up all over the place recently. Why not on ingredients such as dried fruit? In the worst scenario several of these factors may have occurred simultaneously. If this was the case, it was a disaster waiting to happen.

Extra care must be taken when preparing food for the young, the elderly, pregnant women and the infirmed. These people are the most vulnerable and as fate would have it these groups are exposed to the highest percentage of cases of food contamination. As you can see from the breakdown I have given you, more than one factor may be to blame. Trouble starts when the approach is as fault. The only way to minimise food poisoning risk is meticulous attention to detail and correct practice at all levels of an operation like a camp.

A number of people have contacted me in request that I give some information about sterilizing cooking pots and other kitchen utensils. For most of us in the western world it is not absolutely necessary to sterilize pots as long as we make sure that we wash them thoroughly in very hot water and washing up detergent. In other areas of the world or in situations where pots have been out in field conditions for any period of time, especially in areas where disease is prevalent, the need to continually sterilize pots may be a critical factor in the prevention of food contamination, the re contamination of sick people and the promotion of food hygiene in areas where it does not exist.

Firstly we need to look at different types of cooking pots. The easiest type of kitchen cooking utensil to sterilize is stainless steel because we can clean it chemically without changing it’s properties. Other forms of pots present some problems. In Africa it is very common to cook in what in some places is called a “poike”. If I am not mistaken this is an Afrikaans word for a cast iron cooking pot. It is cast from a thick lawyer of cast iron or steel and is designed to sit over an open fire. They come in many different sizes and are usually very heavy indeed. They usually have been treated with blackening so they have an outer covering. They also have a thick carrying handle that is attached to the rim of the pot across it’s diameter.

Another form of cooking pot is the aluminium pot. the advantages of aluminium are that it is lightweight and heats up very quickly. The disadvantages of aluminium are that it reacts to just about every form of chemical including the acid in tomatoes, lemon and eggplants. The metal is relatively weak and handles usually fall off after a period of use and it does not distribute heat very evenly.

Copper is another for of metal use to make cooking pots but utensils made from copper are normally expensive and in my opinion would not be used in areas of the world which require the sterilization of cooking equipment. In any case we can class it as having very similar properties to aluminium from a cleaning perspective.

Probably the oldest and most traditional way to sterilize all forms of cooking equipment is to boil them in boiling water. Adding some salt to the water will help in the disinfecting process and it will slightly increase the boiling temperature of the water. The advantage of this system is that the pots and pans are immediately ready for use after sterilization. The disadvantages are that the equipment has to be 100% clean before going into the sterilization pot and they require a minimum of thirty minutes to biol before it is safe to take them out. Boiling does not ensure that all types of bacteria will be destroyed and some toxins can survive boiling.

Continuing with the theme of using water another efficient way to sterilize pots and pans is with the use of steam. Steam is much hotter than water it will sterilize much more quickly. Steam treatment is OK for all types of metals but Stearn is dangerous and requires special equipment to be able to work with steam safely and efficiently. Like with water the advantage of steam is that equipment can be put straight back into use with no further treatment.

Caustic Soda is the next form of sterilization which I would like to talk about. Caustic Soda destroys all forms or organic material. Concentrated caustic soda needs to be diluted with water and heated to a temperature of no more than 80 degrees Celsius. Caustic soda breaks down at temperatures above 80 degrees Celsius and ceases to be effective. Great care must be taken with caustic soda because it is very dangerous and can cause serious burns and blindness if it gets into your eyes. People using caustic soda should be properly trained and should also wear protective clothing which should include a thick plastic apron, thick neoprene gloves and a full industrial plastic face mask. This chemical is only suitable for stainless steel. Other forms of metal will be effected by the chemical reaction within the soda. Aluminium may even be eaten away completely. The use of caustic soda is also good for removing stubborn cooked on foods. The disadvantage of using soda is that it needs to be washed off dishes completely before they can be used again. If your water supply is not infected you may want to consider rinsing the pots in boiling water to avoid re contamination. Caustic soda will melt the fat in your skin so it has a slimy feel if it is not properly washed off. Wash until this feeling has completely gone. Caustic soda is also good for cleaning glass, ceramic and plastic utensils.

Yet another method of sterilizing kitchen equipment is to soak it in hot water and chlorine cleaning powder. Chlorine kitchen powder is also good for removing stubborn stained on ceramic and glass plates, cups and bowls. This type of sterilization will react a little with aluminium and will remove the oxidized lawyer on the surface of the aluminium which is necessary to remove the toxicity of aluminium. Therefore, I do not advise using chlorine powder to sterilize aluminium. This form of sterilization requires that equipment be soaked for about three to four hours for good results. Similarly to the use of soda chlorine must be washed off completely before re use of equipment.
