Which pairing correctly identifies a hazard type with an example?

• A. Biological hazard — Glass fragments.
• B. Biological hazard — Salmonella.
• C. Chemical hazard — Bone fragments.
• D. Physical hazard — Pesticide residues.

Answer: (B)

Biological hazards are microorganisms or their toxins that can cause disease. Salmonella is a pathogenic bacterium that can cause illness when ingested, so it clearly fits as a biological hazard. In contrast, glass fragments and bone fragments are physical hazards—foreign objects that can injure or cause choking. Pesticide residues are chemical hazards—contaminants from chemicals used in agriculture or storage. Because Salmonella represents a living organism capable of causing illness, the pairing with a biological hazard is the best match. Controls for this type focus on preventing contamination, thorough cooking, and good hygiene to stop the pathogen from entering or surviving in food.
