How do flies and mice pass food-poisioning bacteria on to food?

- Direct contamination: Flies can land on food and deposit harmful bacteria directly onto it. This can happen when flies come into contact with contaminated surfaces, such as garbage cans, animal feces, or sewage.

- Indirect contamination: Flies can also spread bacteria indirectly by contaminating surfaces that people or animals may come into contact with, such as countertops, tables, and dishes. When people or animals touch these surfaces, they can transfer the bacteria to their food or mouths.

Mice:

- Droppings: Mice can contaminate food with their droppings, which can contain harmful bacteria, such as Salmonella and E. coli.

- Saliva: Mice can also spread bacteria through their saliva when they nibble on food.

- Urine: Mouse urine can also contaminate food and surfaces.
