Which of the following is an example of a biological hazard?

A biological hazard refers to any biological substance that poses a threat to the health of living organisms, primarily humans. This includes microorganisms such as bacteria, viruses, fungi, and parasites that can cause diseases. In this context, viruses are recognized as biological hazards because they can lead to various infectious diseases, posing significant health risks in food manufacturing and preparation environments.

Understanding biological hazards is crucial in the food industry, as they necessitate strict hygiene practices, proper food handling, and cooking techniques to prevent contamination and ensure food safety. The identification of viruses as a biological hazard supports the need for training and protocols aimed at minimizing health risks linked to foodborne illnesses.

Other choices, while they represent hazards, do not fall into the biological category. Pieces of plastic are classified as physical hazards, as they pose risks of injury or damage due to their presence in food. Mercury is a chemical hazard, associated primarily with toxic effects from exposure rather than biological danger. Pest hair, although a potential concern for contamination, is often categorized within physical or environmental hazards rather than strictly biological. Thus, identifying viruses as biological hazards emphasizes the importance of controlling these threats in food safety practices.
