Food Hygiene Essentials

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.

Today’s blog entry is going to be a bit different from the type of article I have written up to this point but I hope that you will find it interesting nonetheless. We all need food to survive and we need a varied, balanced diet of good quality food to survive and prosper. In this modern world that we live in we tend to see food as a mere commodity, something that we need, that we can’t do without. Most of us shop very differently to the way our grandparents would have shopped not so many years ago. We scurry around supermarkets piling products into a huge metal basket on wheels. Our food is stuffed into plastic containers, tin cans, foil wrappings and waxed cardboard with little thought to what the substances that those packagings are actually doing to our food.

As a spiritual person I am very much aware that our food has within it the spirit of the beings that lived before us and now make up the matter which we call earth. Food has dynamic energy and still interacts with it’s surroundings both during it’s growth phase and after it has either been harvested of slaughtered. To my intense disappointment and distress our food is not shown the respect it deserves from many of those who grow it and process it.

One thing that we need to remember it that the energy that is held within our food goes into our bodies and is assimilated into our body tissues for energy, growth and maintenance. The quality of the food we eat in terms of energy has direct bearing as per the quality of the end product that we are able to produce. This could for structural purposes, for cognitive purposes, for defence purposes and a range of other things.

For many of us the option of owning our own private vegetable patch and private orchard is not really within the realms of possibility but farmers markets are popping up all over the place that offer produce that has been grown organically with more positive emotion, slaughtered more humanely with far less stress and packed and processed in a much more tranquil and positive surrounding by people who truly love what they do. Processed products on offer in farmer’s markets can incluse produce such as could breads,cheese, pickles, jams, cakes, pies, sausages, hams and many many other types of pre prepared produce.

Similarly, restaurants can be very stressful places, particularly in the kitchen area. Although a chef may strive to present you with a dish that is a veritable work of art, the human interaction inside the kitchen is very often very stressful and generally negative with a lot of shouting, cursing, sometimes violence, humiliation, emotional castration, jealousy, hate, resentment, exploitation, degredation, disrespect and more. Believe me, I have worked in quite a few kitchens and I have seen a few things.

The intent that the chef has in creating his dish is spoiled and cancelled out by the general ambiance with the kitchen and the restaurant. Personally I can sense these energies and I will refuse to eat in such places but in circumstances where people might get offended if I refuse point blank, I make sure that I don’t come back to the same restaurant for a very long time.

I like to research where I eat. I look at the produce they use, how it delivered, how the management treat the kitchen staff including the waiters and when I am satisfied that the energy flowing within an establishment is one with which I revere, Then I will eat there. Food with good energy feeds your spirit as well as hunger. You feel elated, not in the egotistical sense but in a way that spreads to every corner of your being.

By saying a blessing or prayer quietly to yourself before eating the food in front of you you are greatly restoring good energy within the food you eat. The energy of the spirits within the food will understand what you desire of it and will not let you down. The reason for this is that you could be helping a spirit on its journey onward into eternity by giving it direction. In this way the energy will not remain stuck and confused within you. May everything you eat feed your body soul and spirit and give your life quality and purpose.

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.

Last week I received a phone call from the head office of a catering company that operates a number of large kitchens up and down the country. The voice at the other end of the line asked me to conduct an independent kitchen hygiene survey in one of their kitchens. I was asked to do a check which included inspecting the condition of the kitchen before and at the time of the arrival of the staff for work. The purpose of this check was to check the level of food hygiene awareness of the staff and the application of food hygiene training in practice, to see if the chef had conducted an adequate inspection of the kitchen before releasing the staff at the end of the shift and to look into the level of pest interaction with the kitchen overnight.

I have done this kind of check before. My job was to walk around the kitchen, dining room and storage areas of the kitchen and to submit a written report within two hours of finishing the inspection to the head office. If my finding were below a certain standard a Representative from head office would visit the kitchen in the early afternoon and hold an emergency meeting with the kitchen manager and the chef. The kitchen manager had been told of my scheduled visit at eleven o’clock on the evening before the visit.

I have to stress this is a kitchen which has had no serious cases of food poisoning in it’s entire history. Considering the findings of the report this may seem surprising to you. As I have stated before, most of us never really know that we are walking along a food contamination knife edge. I cannot allow you to see my written report due to client confidentiality but I can let you read my verbal notes which I recorded on my pocket recorder at the time of the inspection.

I arrived at the rear delivery ramp of the kitchen at five thirty in the morning. One half hour before the kitchen staff were due to arrive. The managers and two dining room workers were already on site.

The points will be numbered:
Kitchen Ramp:

1) Three pallets left unattended on the ramp.
2) Crows pecking sweet corn kernels on the fresh veg pallet.
3) Middle pallet containing fresh chicken legs, blood dripping onto ramp, flies starting to land on the boxes.
4) Vegetable fridge door left open.
5) Dry produce store room door left open.
6) Sparrows flying in and out of dry store room.
7) Cleaning chemicals left on ramp from day before.
Dirty service trolleys left on ramp from day before.
9) Water hose pipe left uncoiled from day before.
10) Empty produce boxes left on ramp from day before.

Kitchen:

11) Work surfaces dirty with water stains from day before, underside of tables dirty, table legs dirty. Dried raw chicken pieces found stuck on two table legs.
12) Shelves above work tables cluttered with disposable coffee cups. Cigarette buts inside coffee cups. Dirty plates, bowls and cutlery left on shelves. Dead flies on shelves. Shelves show no evidence of being cleaned.
13) Cobwebs in corners of ceilings.
14) Unclean linings in bread baskets.
15) Dirty cooking trays left in water overnight.
16) Dining room manager spraying degreaser onto barbecue grill vent in close proximity to food being set out for breakfast.
17) Egg trays on work surfaces in dining room and kitchen.
18) Unwashed parsley, dill and coriander put onto work table surface by kitchen worker.
19) Boxes of unwashed vegetables put onto work tables by kitchen staff.
20) Box of unwashed red peppers placed on top of chopping board.
21) Combi steamers greasy and with fallen food on oven floor.
22) Electronic thermoporters unclean. Water trays not emptied. Dirty water and thick layer of lime in water trays apparently not changed for several days.
23) Bad smell coming from inside dish washing machine. Filters not cleaned at the end of the night shift.
24) Fryer lids sticky and greasy.
25) Cockroaches coming out of fryer side panels after being turned on.
26) Small particles of food and stains evident on ceramic wall tiling behind cooking pots and fryers.
27) Stagnant water in cleaned plastic tubs. Tubs not inverted after washing.
28) Bread cutting machine left untidy with thick layer of crumbs let on the machine and floor after use.
29) Meat slicing machine not cleaned with soapAfter use. Fatty lawyer evident after previous day’s use.
30) Plastic tubs containing thawed raw meat left uncovered in fridge.
31) Condensed water dripping onto food trolleys from fridge ceiling.
32) Food trolleys in fridge not covered.
33) Fridge temperature gauge not working.
34) Evidence of mildew, liquid egg, and various sauces on fridge shelving.
35) Fridge floors wet and muddy.
36) Service trolleys not properly cleaned at the end of the day and not being cleaned between tasks.
37) Head Chef wearing very dirty trousers.
38) Staff smoking and drinking coffee in the kitchen.
39) Staff rest area not cleaned the day before, coffee cups and dirty eating plates and cutlery left on tables. Floor filthy. Cat present in staff eating and rest area.
40) Staff not wearing head covering and failing to wash hands before entering the kitchen area.
41) Disposable surgical gloves left on work surfaces after use.
42) No Liners in trash cans.
43) Boxes of frozen vegetables left on kitchen floor by store staff.
44) Rats seen in empty box collection cage.
45) Cats seen in most areas around kitchen and dining room.
46) Birds seen in Kitchen store and in dining room.
48) Blocked sink in vegetable cleaning area. No sign of technical staff for twenty minutes.
49) Meat left to thaw outside of fridge.

These were my findings within the period of forty five minutes of arriving in the catering kitchen. As you can well imagine my grading was not very favorable on that particular day. I know that the head chef and kitchen manager were place on probation in view of these findings. A repeat survey is to take place within a period of one month.

One job that people really fear doing most in commercial kitchens is cleaning the tough grease off equipment, drains and vents. Why? Because it nearly always involves the use of strong caustic soda based substances.

These substances cause injuries if not handled properly. They can cause blindness if they get into eyes, they can cause breathing problems and they can cause severe chemical burns to the skin. In addition they are a food safety hazard and there is always the risk that they will enter food that is in the work area.

I have used these substances for many years because we really had no other solutions to the cleaning challenges we had to deal with on a daily basis. I used to dread having to use these substances and yet, being the type of person I am I would do most of this work myself because I knew that my staff would cause themselves injury.

However, there is no longer a reason to use such potentially dangerous substances because we have now entered the era of the steam vapour cleaning system. Whereby formally you would spread degreasers onto a surface or scrape a surface for hours on end with a spatula now you can do the same work in a very short space of time using a steam vapour cleaning system.

In commercial kitchens not all work surfaces or cooking trays are stainless steel. It is better if they are but some products use aluminium to make a product less expensive. The advantage with the steam vapour cleaning system is that it cleans any surface, stainless steel, ceramic, aluminium, rubber, plastic, wood or Teflon.

It will clean, grease, grime, mould and lime. What’s more you don’t have to evacuate a twenty meter radius when using it. Once the hard grease and grime is off it becomes easy to maintain clean surfaces because very little time is needed for maintenance. In fact, the only chemical you will regularly need in your kitchen is ordinary washing up detergent. I strongly advise using a steam vapour cleaning system in all types of kitchens. Remember, the cleaner you kitchen is kept, the fewer vermin problems you will have and the easier it becomes to clean your kitchen the cleaner it will be kept.

For many years my institutional kitchen operated in a very traditional way. We had a weekly menu and we would prepare each meal on and for the day it was intended. We would do essential preparations the day before after the day’s meal was closed. I was very proud of the variety and quality of the meals we put out. Very few five star hotels could match us for product quality, variety and taste.

One day an opportunity was presented to me. I was asked to prepare food for two other institutions the same size as my own. I knew that we were hard pressed to put out our own meal so how was I going to triple the work load. As things were my staff were going home at the end of their physical strength. It is a really hard days work to prepare food for one thousand five hundred people per day. I was going to have to think of a way of re organizing my whole operation without compromising quality.

One day I was reading a professional food industry magazine when I saw an advertisement for a new piece of equipment that looked, well, very much like an oven to be honest. The piece of equipment in question was called a blast chiller. The ad. claimed that the system could cool forty trays of food to twenty degrees in less than an hour. This claim intrigued me and so I contacted the company which was marketing the product.

After introductions the guy in the showroom said to me, “why waste time talking, lets go to see the product where it is being used every day”. I agreed at once, after all, actions speak louder than words.

After seeing the machine in action I knew that I was going to have a very personal relationship with a blast chiller. I knew that this one piece of equipment was the key to being able to triple my work load. The blast chiller was ordered and arrived one month later.

Without putting too much strain on the staff I had been making bigger batches of food and freezing them in my deep freeze. I knew that this was not ideal without my blast chiller but I had to have some inventory to be able to make the switch from cooking for 1500 people to cooking for over 4000 overnight.

I arranged a time for a staff meeting and told them how they would be working from then on. I told them that we would not be working as we had worked up to now. we would not be preparing meals for a daily deadline, instead we would be preparing stocks of food for the freezer. We would be reducing our daily task load from over eighteen Items per day to three of four. I told them that this would allow us to prepare bigger loads with fewer periods of transition from one task to another and we would be greatly reducing the risk of cross contamination by having fewer things flying around the kitchen.

What we would continue to prepare on a daily basis were soups, salads and things that couldn’t be frozen. All seemed interested in the new system but seemed a little puzzled. I asked them to trust me, they would not be working any harder and they would be given a wage raise for handling the extra volume.

Staff at the other two kitchens was cut to one third of what it previously was. It would be their job to receive the food the day before and to heat the meal up on the day. I bought small truck for transporting the food to the other kitchens. It was a truck with a cooler unit inside so that the food could be kept at a constant temperature of two degrees.

And so we started pumping our vast quantities of hot food which was rapidly cooled by the blast chiller and sent to one of the freezers within an two hours of coming out of the oven. To be able to do this operation successfully I took control of all the cooking trays and baking trays from the other kitchens We all used gastronorm trays so that did not present any problems. I did have to buy about 200 more but I had taken that into account and added the price to the cost of the food the others bought spread out over a two year period which I calculated to be the life expectancy of a cooking tray.

The system was working very well and the clients seemed very happy. Soon two more kitchens approached me to prepare food. I agreed to take on the extra work. I employed two more experienced members of staff and to tell you they truth we hardly felt the difference. I was now preparing food for upwards of seven thousand diners per day. The staff we now working very systematically, there was very little panic, everybody was smiling. What could be better.

My job was to formulate the recipes in such a way that diners would not feel that they were getting the same food all the time, to make sure all members of staff knew what they had to do, to make sure that the kitchen was cleaned before moving from an uncooked stage to a cooked stage and vise versa and to make sure that the end kitchens were handling and presenting the food correctly so that at each end dining room the presentation would look identical to all the other places.

And now I am going to tell you what the real key to running such a big operation is. Good technical staff. An operation like this needs  up keep and hitches do happen regularly. You need to be able to rely on your technical staff to solve problems quickly and professionally. I also aways have one oven more than I need. For this type of work I prefer to use a combi steamer oven. It is very versatile and is adaptable to many different cooking climates.
