The FDA calls them food defects and defines its permissible "Food Defect Action Levels" as listed in their online booklet to be "the levels of natural or unavoidable defects in foods that present no health hazards for humans."

The list of "defects" includes rodent feces (excrement), rodent hair, molds, whole insects, insect parts, beetle eggs, beetle larvae, and more.

Would you like a taste of the foods that we consume according to the FDA standard’s "Protecting and Promoting Your Health"? Here are a few samples of upper acceptable limits gleaned from the publicly available FDA booklet:

Whole Allspice: 5% berries per weight are allowed to be moldy,

Ground Allspice: 30 insect fragments per 10 grams; 1 rodent hair per 10 grams,

Ground Cinnamon: 400 or more insect fragments per 50 grams, 11 or more rodent hairs per 50 grams.
