Physical contamination occurs when foreign objects or materials unintentionally mix with food or products, posing risks to health and safety. Common examples include hair, glass shards, metal fragments, or plastic pieces that can accidentally enter during production, processing, or packaging. This type of contamination can lead to serious injuries if ingested and can also result in product recalls. To prevent physical contamination, industries often implement strict hygiene practices, regular equipment maintenance, and thorough inspections to ensure that food safety standards are met and that consumer safety is prioritized.
