What are the 3 food contaminants?
The three types of contamination are biological, physical, and chemical . However, for the purpose of this article, we will discuss four categories. These include chemical contamination, physical contamination, microbial contamination, and allergen contamination.
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.
Is salmonella a biological contamination?
Biological hazards include microorganisms such as bacteria, viruses, yeasts, molds and parasites. Some of these are pathogens or may produce toxins. ... Examples of biological hazards include Salmonella, E. coli and Clostridium botulinum.
What are the 3 types of cross contamination?
There are three main types of cross contamination: food-to-food, equipment-to-food, and people-to-food . In each type, bacteria are transferred from a contaminated source to uncontaminated food.

What are possible causes of cross contamination?
Cross-contamination is how bacteria can spread. It occurs when juices from raw meats or germs from unclean objects touch cooked or ready-to-eat foods .
How long can foods safely remain in the danger zone during preparation?
Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” Never leave food out of refrigeration over 2 hours .
What is an example of a biological toxin?
Examples include botulinum toxins (A-G) , tetanus toxin, and staphylococcal enterotoxins (A-F), which are produced by bacteria; tetrodotoxin, and ciguatoxin, which are produced by animals; and ricin toxin, tricothecence mycotoxins, and abrin, which are produced by plants.
Is human hair a biological contamination?
Hair is a source of microbiological contamination as the human scalp often contains Staphylococcus Aureus, a food poisoning organism. Therefore any hair in food can be a root cause of cross contamination and can indeed make us ill.
What is an example of a biological hazard?
Sources of biological hazards may include bacteria, viruses, insects, plants, birds, animals, and humans . These sources can cause a variety of health effects ranging from skin irritation and allergies to infections (e.g., tuberculosis, AIDS), cancer and so on.
