Food Safety And Hygiene Flashcards
What does physical contamination include
Pieces of metal or plastic entering food during production. Parts of food products, which should have been removed during processing eg. Pips, stones, shell, bones or stalks, can contaminate the end product.
Three types of food contamination
Physical, chemical and micro organism
Physical contamination also includes
Fragments of food packaging or objects from careless food handling such as plasters, jewellery and hair. Pets can also contaminate food with their droppings, saliva and urine.
What does chemical contamination include?
Metal residues, pesticides, bleached and cleaning materials.
Why is the correct storage of cleaning products important
As they can taint food products
The Careless use of chemicals in a food preparation environment could contaminate food. Expand
Chemicals used in agriculture and farming methods could leave residues in food products such as antibiotics ad hormones in meat. The use of food additives in incorrect quantities can pose a risk of health.
Microorganism contamination: explain food change during storage
The process can affect the colour, flavour, texture and appearance of food. Usually the changes in food are harmless and sometimes they are desirable - softer fruit or tenderising red meat.
Micro-organism contamination: food changes during storage. The changes are caused by microorganisms and enzymes. What are microorganisms
Are very small living organisms which cannot be seen with a microscope. They include yeasts, viruses, moulds and bacteria.
Four types of microorganisms
Moulds yeasts viruses and bacteria
What is the name of the bacteria which are harmful to health
Pathogenic bacteria
Food poisoning can be caused by eating food which is contaminated with live bacteria. What can it also be caused by
Eating the waste products, spores or the toxins which bacteria may produce
What are moulds
Are tiny plants or fungi which grown on the surface of food.
What do moulds produce
Spores which can travel in the air to generate new growths.
What conditions to mould prefer to multiply
Warm and moist
When can moulds be used
Food industry to produce speciality cheeses such as Stilton, Roquefort or Camembert
