A pathogen is considered what type of contaminant?

There are three types of contaminants to food. They are Biological, Chemical, and Physical.
- Biological contaminants are pathogens such as viruses, bacteria, fungi, and toxins (poisons) produced by some seafood, mushrooms, and plants.
- Chemical contaminants are chemicals that may accidentally contaminate food. Cleaning agents, insecticides, and polishes are some examples.
- Physical contaminants are things like chicken bones, glass, dirt, or bag ties that may accidentally fall into food. In the case of bones, some foods (soup for example) usually should not contain bones.
