What immediate action is essential if a food supply is contaminated by pests?

Thoroughly cleaning contaminated areas is essential because it addresses the immediate risks posed by pests. When food supplies are contaminated, pests can introduce harmful bacteria or pathogens that can lead to foodborne illnesses. Cleaning the contaminated area helps to remove these hazards, ensuring that any droppings, food residues, or nesting materials left by pests are properly disposed of. This action not only protects the integrity of other food supplies but also aids in preventing further pest attraction.

Additionally, thorough cleaning supports maintaining a safe food environment by adhering to sanitation standards required in food handling and preparation areas. It is the first critical step before any further actions, such as inspecting and possibly discarding contaminated food.
