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

• A. Person-to-Food
• B. Physical Hazards
• C. Pathogen
• D. Pest-to-Food

Answer: (D)

Pests acting as carriers of disease is the idea here. When animals or insects move around, they can pick up microbes from dirty surfaces, garbage, or sewage and deposit those pathogens onto food, utensils, or prep areas. That’s pest-to-food contamination—the pests serve as vectors that transfer the contaminants to food. If a person contaminates food, that’s a different route—person-to-food contamination, not about pests. Physical hazards are non-biological contaminants like glass or metal fragments, which aren’t microbes. A pathogen is the microbe causing illness, not the way it’s spread. So the correct concept is pest-to-food contamination, where pests transfer pathogens to food.
