Cross-contamination that spreads through animal or insect vectors is called?

• A. Parasites
• B. Personal Hygiene Program
• C. Physical Hazards
• D. Pest-to-Food

Answer: (D)

Cross-contamination via animal or insect vectors happens when pests carry pathogens on their bodies or in their waste and transfer them to food or food-contact surfaces. This route is specifically described as pest-to-food contamination, because the pests themselves are the carriers introducing contamination. Other options don’t fit this situation: parasites are organisms that live on or in a host and don’t describe the contamination pathway from pests to food; a Personal Hygiene Program is about sanitation practices to prevent contamination, not the mechanism of contamination; physical hazards are foreign objects like glass or metal, not biological contamination by pests. Focusing on how pests can relay pathogens to food highlights the importance of pest control and safe handling to keep food uncontaminated.
