What are four sources of food hazards that could contaminate food?

There are four primary categories of food safety hazards to consider: biological, chemical, physical, and allergenic. Understanding the risks associated with each can dramatically reduce the potential of a foodborne illness.

What are the sources of food contamination and poisoning?

Infectious organisms — including bacteria, viruses and parasites — or their toxins are the most common causes of food poisoning. Infectious organisms or their toxins can contaminate food at any point of processing or production. Contamination can also occur at home if food is incorrectly handled or cooked.

What are the sources of cross contamination?

Common causes of cross-contamination include:

  • Clothing: Dirty clothes can transport bacteria from one place to another.
  • Utensils: Different utensils should be used to prepare different types of foods.
  • Food Handlers: Coughing, sneezing or even touching your face or hair before handling food can cause cross-contamination.

Which is a physical contaminant?

Physical contaminants (or ‘foreign bodies’) are objects such as hair, plant stalks or pieces of plastic/metal that can occur as contaminants in food. Sometimes the object is a natural component of the food (e.g. a fruit stalk) – but in all cases it is important to find out what it is and how and when it got there.
