Which of the following is a physical contaminant?

• A. Broken glass
• B. Hair
• C. Rice
• D. Water

Answer: (A)

Physical contaminants are foreign objects that don’t belong in food and can cause harm if they’re eaten. Broken glass is a clear example because it’s a hard object that can injure someone if it gets into food, potentially cutting the mouth, throat, or digestive tract. While hair can also be a physical contaminant, the hazardous, obvious risk posed by broken glass makes it the best illustration of this type of contamination. Remember to prevent any foreign objects from reaching food by using break‑resistant equipment, inspecting containers and work areas for damage, and handling glass carefully.
