Which of the following is NOT considered a biological hazard?

Damaged packaging is not considered a biological hazard because it pertains to the physical condition of packaging materials rather than the presence of living organisms that can cause illness. Biological hazards typically involve pathogens such as bacteria, viruses, fungi, or parasites that can contaminate food products and pose a risk to human health.

Coughing and sneezing both can release respiratory droplets that may contain infectious agents, making them represent potential biological hazards. Bare body parts can also present a risk when they come into direct contact with food, as they could carry bacteria or other pathogens. On the other hand, damaged packaging might concern issues like contamination or quality but does not directly relate to living hazards, making it the correct choice in this context.
