What type of contamination might hair in food lead to?

Hair found in food is classified as a physical hazard. Physical hazards refer to any foreign objects that can potentially cause harm when ingested, such as hair, glass, metal fragments, or bone chips. These items can lead to choking, cuts, or other physical injuries to consumers, which is why it's crucial for food safety practices to minimize the risk of such contaminants.

While biological hazards are related to bacteria, viruses, or parasites that can cause foodborne illness, and chemical hazards pertain to harmful substances that may contaminate food, the direct concern with hair is its physical presence, making it a clear example of a physical hazard. Similarly, microbial hazards refer specifically to the harmful microorganisms that may lead to foodborne illnesses, which do not apply to the presence of hair in food.
