Physical contamination in food refers to foreign objects that can unintentionally be introduced into food products during preparation, cooking, or serving. Such contaminants can cause injury or illness to consumers.

In this context, hair, nails, or pieces of glass are clear examples of physical contaminants as they are tangible objects that can physically alter food or pose health risks if ingested. This kind of contamination typically occurs when there is a lapse in food handling practices, such as inadequate personal hygiene or insufficient attention when handling kitchen tools.

The other options, while serious safety concerns in food handling, fall into different categories. Chemicals from cleaning supplies are examples of chemical contamination, where harmful substances can leach into food, leading to potential poisoning. Microorganisms or bacteria represent biological contamination, which involves the presence of harmful pathogens that can cause foodborne illnesses. Improper cooking temperatures relate to food safety regulations and can lead to the growth of pathogens, but do not themselves constitute a physical contaminant.

Understanding physical contamination is crucial for food safety practices, as preventing these types of risks can help ensure the health and safety of consumers.
