Which two types of contamination can pests cause?

• A. Chemical and Biological
• B. Physical and Biological
• C. Physical and Chemical
• D. Biological and Allergens

Answer: (B)

Pests can cause physical and biological contamination. Physical contamination occurs when pests, such as rodents or insects, leave behind droppings, hair, or even bodies in food products, which can pose serious health risks to consumers. This type of contamination makes food unsafe for consumption and can lead to illness.

Biological contamination happens when pests carry pathogens, such as bacteria or viruses, that can contaminate food. This can occur through direct contact or indirectly when they come into contact with food surfaces. The presence of live pests or their biological byproducts can introduce harmful microorganisms into the food supply, further increasing the risk of foodborne illnesses.

Chemical contamination, on the other hand, typically stems from the use of pesticides or other harmful substances used to control pests, not directly from the pests themselves. Allergens generally refer to substances that cause allergic reactions, which might not be directly related to pest infestation. Hence, recognizing the primary ways pests contribute to food safety risks emphasizes the importance of pest control and sanitation practices in food handling environments.
