BIOLOGICAL CONTAMINATION. Biological contamination occurs when food becomes contaminated by living organisms or the substances they produce. This includes biological matter produced by humans, rodents, insects and microorganisms..

How is biological contamination prevented?
To slow down bacteria growth and minimise the risk of biological food contamination, Food Handlers must always follow safe food handling practices: Keep high-risk foods (e.g. meat, poultry, seafood, eggs, dairy) out of the Temperature Danger Zone. Properly purchase, store, thaw, prepare, cook and serve high-risk foods.
What are the 5 types of biological hazards?
Biological health hazards include bacteria, viruses, parasites and moulds or fungi. They can pose a threat to human health when they are inhaled, eaten or come in contact with skin. They can cause illness such as food poisoning, tetanus, respiratory infections or parasite infection.
What are 5 biological food hazards?
Examples of biological hazards are: disease-causing bacteria, viruses, parasites, molds, yeasts, and naturally occurring toxins.
How do biological contaminants lead to food borne illness?
Food-borne diseases can be caused consuming food or water contaminated by pathogenic microorganisms such as bacteria and their toxins, fungi, viruses, and parasites. Food can be contaminated both at the source as raw material, and during food processing up to storage and distribution.
What is a biological agent in food?
Biological agents (hazards) of concern to public health include pathogenic strains of bacteria, viruses, helminths, protozoa, algae, and certain toxic products they may produce. Of these hazards, the presence of pathogenic bacteria in foods currently presents the most significant problems internationally.
What is human biological material?
For the purposes of this Policy, human biological materials include tissues, organs, blood, plasma, skin, serum, DNA, RNA, proteins, cells, hair, nail clippings, urine, saliva and other body fluids.
Is a virus a biological material?
Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.
What is considered biological substance? UN3373 Biological Substances, Category B can be human or animal material including (but not limited to) blood and its components, tissue, tissue fluids or body parts being transported for purposes such as research, diagnosis, investigational activities, disease treatment or prevention.
How can we prevent biological contamination in food?
Carefully wash cooking equipment, utensils, and food surfaces both before and after food preparation using soap and water hot enough to tolerate or in a dishwasher that uses water at a temperature that kills microorganisms. Separate cooked meats from raw foods to prevent cross-contamination.
What is a biological hazard in the kitchen?
Biological hazards are foodborne viruses, fungi, bacteria, and parasites. The most common biological hazards to be aware of are E. coli, Shigella, Norovirus, Salmonella, Hepatitis A, and Staph.

What can cause biological spoilage?
Microbial spoilage is caused by microorganisms like fungi (moulds, yeasts) and bacteria. They spoil food by growing in it and producing substances that change the colour, texture and odour of the food. Eventually the food will be unfit for human consumption.
How can we prevent biological hazards to occur in our food?
Prevention of Foodborne Illness
- CLEAN: Wash hands and food contact surfaces and utensils often, between tasks, and if they have become contaminated.
- SEPARATE to prevent cross contamination.
- COOK food thoroughly and use a thermometer to verify the proper temperature was reached.
What are the 5 types of biological contaminants? Biological contaminants include bacteria, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen.
How do biological agents affect human health?
Biological agents include bacteria, viruses, fungi, other microorganisms and their associated toxins. They have the ability to adversely affect human health in a variety of ways, ranging from relatively mild, allergic reactions to serious medical conditions—even death.
