What is an example of a biological hazard that can contaminate food?

Viruses are a significant example of a biological hazard that can contaminate food. These microorganisms can lead to foodborne illnesses, which can cause serious health issues. When food is handled by someone who is infected or comes into contact with contaminated surfaces, viruses can transfer to the food. Unlike cleaning agents, which are considered chemical hazards, or improperly cooked meat and expired ingredients, which relate to physical and chemical safety respectively, viruses represent a direct biological threat to food safety.

Understanding the implications of biological hazards like viruses is crucial for maintaining food safety practices. Maintaining good hygiene, especially in food preparation environments, is essential to reduce the risk of viral contamination and ensure that food remains safe for consumption.
