Question

If a hair gets into food, it could be introducing ___________ contamination into the food?

Answer 1

Wouldn't it be physical contamination? However, "Physical contamination happens when actual objects contaminate foods. Sometimes when a food is physically contaminated, it can also be biologically contaminated. This is because the physical contamination might harbour dangerous bacteria, for example a fingernail."

Answer 2

Biological contamination is when bacteria or toxins contaminate food and is a common cause of food poisoning and food spoilage
