Which of the following are examples of physical hazards?

• A. Glass, screws, stones, hair
• B. Bacteria, Viruses, Moulds, Parasites
• C. Peanuts, tree nuts, sesame seeds, eggs
• D. Lye, Bleach, Ammonia, Acids

Answer: (A)

Physical hazards are tangible, non-food objects that can contaminate food and cause injury if swallowed or bitten. In HACCP terms, they are different from biological hazards (microorganisms like bacteria, viruses, moulds, parasites) and from chemical hazards (substances such as cleaning agents and acids) or allergen-related concerns. Glass, screws, stones, and hair are classic examples because they are real objects that could inadvertently end up in food and pose a choking or injury risk. The other options describe living organisms or chemicals that cause harm in different ways, or allergens that trigger reactions rather than physical contamination.
