What is an example of a physical contaminant in food?

Hair or metal shavings are classified as physical contaminants in food because they are foreign objects that can accidentally find their way into food products. Physical contaminants can pose risks to consumer safety, as they may cause injury or discomfort if ingested. This category includes items like glass shards, plastic pieces, or any other tangible matter that should not be present in food.

Chemical residue refers to substances left from pesticides or cleaning agents, which are categorized as chemical contaminants. Bacteria or viruses fall under biological contaminants, which include any living microorganisms that can cause foodborne illness. Excess moisture can lead to spoilage or mold growth, but it does not constitute a physical contaminant since it doesn’t involve foreign objects that could result in injury. Understanding these distinctions is crucial for food safety and preventing contamination incidents in food handling and preparation.
