Pest ControlQuestion 227 of 319
A bin of bulk flour was clearly contaminated by mouse droppings overnight. What must be done with the flour?
a.Donate it to a non-food charity so it is not wasted
b.Sift it well, then use it for items that will be baked at high temperature
c.Discard the contaminated flour; food exposed to vermin or their droppings must not be served
d.Set the flour aside for one week and re-evaluate
Explanation
Any food exposed to vermin or rodent droppings is considered adulterated and must be discarded — sifting or baking does not reliably remove pathogens such as Salmonella or Hantavirus-related risks. After disposal, clean and sanitize the area and adjacent food-contact surfaces, then notify the PIC.
