Which of the following is considered a physical hazard in food?

Bone fragments in food represent a physical hazard because they can cause harm to consumers when ingested. Physical hazards refer to any foreign objects that can accidentally contaminate food and potentially cause injury or illness. These can include items like hair, glass shards, plastic pieces, and, of course, bone fragments from meat products.

In food safety, it is critical to ensure that food is free from such hazards to protect consumers from physical injury while eating. Recognizing bone fragments as a physical hazard highlights the importance of careful food preparation and handling, including thorough checks during the deboning process.

The other options, while they represent different types of hazards that can occur in food handling—such as biological or chemical hazards—do not fit the definition of a physical hazard. Raw meat, while it can pose a biological risk due to pathogens, isn't a physical object that could cause immediate injury when eaten. Improperly cleaned surfaces could lead to cross-contamination with biological contaminants, whereas chemical spills relate to chemical hazards. Understanding these distinctions is essential for maintaining a safe food handling environment.
