Cheesemaking is an area of food hygiene that requires particular attention to cleaning. It is not enough to use ordinary detergents in cheesemaking, special detergents are sold to dairies by their dairy products suppliers. This includes the chemicals used for cleaning the pasteurising machines. In fact, a good cheesemaker spends around 50% of his time cleaning.
Cheese can only be made in vats that can tolerate being washed in caustic soda. This means that the only metal that can be used is stainless steel. All vats and stainless steel work surfaces must be washed after each job, after the end of the working day and before work begins in the morning. This also includes milk holding tanks and their pipes which are washed in an internal washing system using caustic soda in water that is heated to 65-70 degrees Centigrade.
The soda is sprayed into the tank by a pump via a rotating sprinkler. After the cycle has worked for the correct period the soda is sent into the drain, the tank is then sprayed by hand to get rid of all soda residue, including sending some through the sprinkler, then filled with an adequate quantity of fresh water which is pumped through the pipes to wash out any soda remaining in them. The pasteuriser is also undergoes CIP (cleaning in place), as soon as the milk has been pasteurised and also at the beginning of every working day before milk is passed through it to be pasteurised.
Cheese dairies usually only work making one type of cheese. However, some “boutique” dairies make a selection of cheeses. It is important to keep the production of cheese that incorporate the use of molds well away from cheeses that do not have molds in them because because it is almost impossible to prevent mold cross contamination. Even a single mold spore in a block of maturing cheese can cause it to go runny and take on entirely different characteristics from those desired and the whole maturation room will be infected with cheese mold spores.
If you make cheeses remember these principles. When making cheeses nothing else should be in the area during the whole process. Personal hygiene is of utmost importance. Hands washed to the elbow in very hot water and detergent, no rings, no watches, no bracelets. Wear gloves whenever handling milk products and change gloves if they are surgeons gloves or wash them frequently in hot water and detergent if they are not disposable ones.
Mad cow disease is a classic example of how failure to adhere to the first of the eight principles of food hygiene can cause both dire risk to those who come into contact with meat infected with mad cow disease and cause terrible suffering for cattle. The need to make sure that animals are reared properly includes how and with what they are fed. The exact meaning of this statement will become clear as you read this article. The diligence needed at each and every stage of food production and food preparation is absolutely vital in order to maintain the full integrity of food safety. Below you will find an explanation of mad cow disease that will give you insight and understanding of this terrible disease.
Mad cow disease or Bovine spongiform encephalopathy (BSE for short) is a neurodegenerative disorder of the central nervous system of cattle of all breeds. It is believed (although not 100% proven) that this disease is caused due to the feeding of animal tissue (usually from cattle by also from sheep or pigs) to cattle.
It is common practice nowadays to feed cattle proteins from animal sources. This may be bone meal, blood meal, brain tissue meal or even feather meal. The reason why cattle are fed animal protein is because the protein levels that are present in most plants are relatively low and some strains of bacteria in the cows rumen break them down into undesirable fatty acids such as butyric acid which are less than ideal for the production of milk and flesh mass on beef cattle. (Acetic acid is best for milk production and propionic acid produces the best muscle mass).
The thing that farmers and industrialists alike are constantly looking for is protein types that the bacteria resident with the rumen will not recognise and therefore will pass through the rumen unaffected by the bacteria and pass into the true stomach where they will passed into the bloodstream through the cows intestine. For this technique to be successful, the farmer must alternate the type of protein given to the cow in its feed so that the bacteria of the rumen will not grow to recognize it and hence metabolise it.
Animal proteins contain prions which are proteins that can change the structure of other proteins that they come into contact with. Factories that make animal protein feed (Often in the far east) are renowned for not adhering to procedure and this can cause fluctuations to happen both in the processing time and temperature levels. You see, if the proteins are properly cooked, they will not cause any damage because when cooked, proteins change their structure.
The effect of eating improperly processed protein feed can cause the prions within the protein of the feed to change the structure of the proteins of the cattles brain and spinal cord. This causes the tissue to become spongy meaning thet there are empty spaces within the tissue where there should have been nervous tissue. This wasting and structural change of the cows brain tissue cause the signals that come from the brain to malfunction causing the cow to appear to have fits and seizures. This condition can take up to five years to develop in the cow.
Although few cases were reported above the norm, in technical terms, this condition can be passed on to humans especially where meat is only lightly cooked (or red in the middle). This disease cost farmers billions of dollars worth of damage , especially in the UK where some six million cattle either died because of the disease or were slaughtered in an attempt to eradicate it.
It is believed that some bad feed is still being exported from the far east, (especially from India).
Probiotics are live bacteria that are beneficial to our health, when eaten in an adequate amount. It is important for our large intestine to maintain a healthy count of these “good” bacteria, as it helps to prevent bad bacteria from growing in the bowel or entering the body through the wall of the intestines to cause infection.
Probiotics are found naturally in foods mainly diary foods, for example probiotics are found in yogurt, fermented and unfermented milk, some juices and also some soy beverages. They can also be taken in the form of a dietary supplement (for example, capsules, tablets and powders) and in some other forms as well, the bacteria in these supplements may have been present originally or it is possible they were added during preparation.
There are numerous health claims associated with the intake of daily doses of probiotics, some of these are:
* Enhanced immune system * Aids in preventing and treating colon inflammation * Increased ability to digest food
* Therapeutic for viral respiratory tract infections by enhancing the overall immune system * Reduces lactose intolerance * Reduces incidence of yeast infection * Increases ability to assimilate the nutrients from food
* Alleviates many common digestive disorders such as constipation, diarrhoea and IBS
Digestive health can affect other areas of our health – weight, energy and immunity – in ways we
might never have imagined. It`s important to understand the link between digestive health and overall wellness.
Here are some useful tips to help you maintain a healthy digestive system
• Eat more fruits, vegetables and whole grain products
• Drink lots of water – Water plays a key role in our digestion. It helps break down the food in our stomach, aids in dissolving nutrients and prevents constipation.
• Eat less fatty foods – The more unsaturated fat or transfat you consume, the more your digestive system is strained.
• Avoid processed foods – These types of food have little nutrition in them and often contain large amounts of saturated fats and preservatives that hinder proper digestion.
• Eat slowly and moderately – It`s common sense. Eating in a rush and consuming large portions in one sitting will definitely put a lot of stress on your digestive system.
• Quit smoking – It certainly can harm the digestive system, contributing to diseases such as heartburn, peptic ulcers, gallstones, liver damage and colon cancer.
• Drink less alcohol – Excessive alcohol intake can lead to cirrhosis of the liver. Furthermore, it can inflame the lining of your stomach and cause symptoms of heartburn.
• Exercise regularly – Cardiovascular exercise helps strengthen the abdomen muscles. Also it stimulates the intestinal muscles to push digestive contents through your system and there`s no reason for you to feel sluggish and lethargic.
• Reduce stress in your personal life – Stress has a negative effect on the nerves of the digestive system, which in turn affects the process of digestion.

This is a report pertaining to a serious mistake or food safety misjudgement by a colleague of mine regarding a substance known as Carboxymethyl Cellulose (or CMC for short). CMC is used as a thickening agent in the food industry. It is often used in the soft drink industry, dairy industry and ice cream industry. CMC is insoluble and requires a medium to carry it in suspension until it can be mixed into the liquid product. Such mediums can be sugar syrup or a vegetable oil. It is a problematic ingredient to use that requires a great deal of worker proficiency.
Products that contain Carboxymethyl Cellulose are usually marked with the ingredient code E466. When used correctly this ingredient is considered safe and it is a good source of additional cellulose (fiber).
My friend is a very experienced food technologist and he should have known better than to do what I am about to tell you. During a visit to his doctor he was advised to add more fiber to his diet. No being a great eater of vegetables my friend decided to find a more creative solution to adding fiber to his diet. At first he targeted dietary supplement that are available at any health food store or pharmacy. After a while he decided that these products were too expensive and so he started to look for even more creative solutions to adding fibre to his diet.
Working in the food industry meant that he had access to many types of raw materials. Initially he started to drink industrial grade pectin which he mixed in a little syrup using a blender and once the pectin was suspended in the syrup he then added fruit juice. Seemingly, bit by bit he turned himself into a sort of human guinea pig and decided to become more ambitious in his quest for the ideal fiber to reduce his cholesterol levels.
He decided to experiment with CMC. Starting with quite low proportions he slowly got more ambitious and began to steadily increase the dosage. After not seeing my friend for some time I decided to call his wife to find out what had happened to him. On hearing my voice his wife immediately burst into tears and told me the story about the CMC and went on to tell me that he had developed a very severe intestinal blockage and that the only way to save him was by opening his intestine in several places to extract the lumps of carboxymethyl cellulose that had formed inside his gut.
I decided to tell you this story to emphasize the point of exactly how dangerous it can be to use food ingredients in ways for which they are not intended to be used. My friend, who is actually an expert in food hygiene and food safety fell pray to his own need to medicate himself cheaply. He wagered that his knowledge and experience were enough to take a calculated risk in using industrial grade materials for use on himself in ways which had never been tested. Now he is paying the price for that mistake.
