Which of the following is an example of a physical hazard in food?

A piece of broken glass or metal in food is a clear example of a physical hazard because it involves foreign objects that can cause harm to individuals consuming the food. Physical hazards are typically defined as any extraneous material that could potentially injure a person. These may include items like shards of glass, pieces of plastic, or metal fragments, all of which can cause cuts, choking, or other injuries if ingested.

In contrast, bacterial contamination constitutes a biological hazard related to harmful microorganisms that can lead to foodborne illnesses. Chemical residues point to residues from pesticides or cleaning agents, which are examples of chemical hazards. Improper cooking temperature relates to food safety concerns regarding the potential for bacterial growth, but it does not represent a physical hazard. Understanding these distinctions is crucial in food safety management to ensure that food prepared for consumption is free from potential dangers.
