Which is an example of a physical hazard preventive control?

• A. Time/temperature monitoring
• B. Allergen labeling
• C. Supply chain programs
• D. Process controls such as (filtering, metal detection, x-ray devices)

Answer: (D)

Physical hazards are foreign materials like metal, glass, plastic, or stone that could contaminate food. A preventive control for these hazards is something that either removes or detects those contaminants during processing. Process controls such as filtering to remove particles, metal detection to catch metal fragments, and x-ray inspection to identify various contaminants directly address physical hazards in real time, making them classic examples of physical hazard preventive controls. Time/temperature monitoring, on the other hand, is about controlling biological hazards by keeping temperatures in safe ranges, not about removing or detecting physical contaminants. Allergen labeling communicates information to consumers about potential allergen presence, not about preventing physical contamination. Supply chain programs focus on safety risks from suppliers rather than on detecting contaminants within the processing line.
