Which of the following is NOT a chemical hazard in food?

Chemical hazards in food refer to harmful substances that can contaminate food products and pose a risk to health. The correct answer, which identifies hair as not being a chemical hazard, highlights the distinction between physical and chemical hazards.

Hair is classified as a physical hazard, meaning it can cause injury or discomfort but does not cause chemical contamination. Ingesting hair typically does not result in chemical reactions or toxic exposures; instead, it might cause choking or discomfort.

In contrast, ciguatoxin, prescription medicines, and roach spray are all categorized as chemical hazards. Ciguatoxin is a toxin produced by certain algae and can accumulate in fish, leading to foodborne illness. Prescription medicines can contaminate food if someone has consumed them improperly, affecting health. Roach spray, a pesticide, is also a chemical that can result in poisoning if it contaminates food.

Thus, identifying hair as a non-chemical hazard helps clarify the types of risks associated with food safety and the potential for contamination.
