Glass represents which type of contamination?

• A. Biological contamination
• B. Chemical contamination
• C. Cross-contamination
• D. Physical contamination

Answer: (D)

Physical contamination occurs when a non-food item ends up in food. Glass is a foreign material that can injure someone if swallowed or chewed, so it fits this category. Biological contamination involves microbes or their byproducts, while chemical contamination involves unwanted chemical substances. Cross-contamination refers to the transfer of contaminants from one surface or food to another, not to a contaminant type itself. So, glass is a physical contamination. To prevent this, maintain intact glassware, inspect packaging, store glass away from food contact areas, and implement screening or detection for foreign objects.
