It's OK to Eat Poop - No Really, The Government Says It's OK

Title 21, Code of Federal Regulations, Part 110.110 allows the Food and Drug Administration (FDA) "to establish maximum levels of natural or unavoidable defects in foods for human use that present no health hazard". The FDA set these "maximum levels" of "defects" because, in their words, "it is economically impractical to grow, harvest, or process raw products that are totally free of non-hazardous, naturally occurring, unavoidable defects".

According to the FDA guidelines, "defects" can refer to, but are not limited to, the following examples:

• Copepods and Pus Pockets in Red Fish and Ocean Perch Fillets - The maximum allowable limit is 3% of the fillets examined contain 1 or more copepods accompanied by pus pockets.
• Rodent Hairs in Apple Butter - An average of 4 rodent hairs per 100 grams of apple butter is "acceptable".
• Insect Filth in Peanut Butter - An average of 30 insect fragments PLUS an average of 1 rodent hair per 100 grams is allowed.
• Maggots in Canned Mushrooms - An average of not more than 20 maggots of any size per 100 grams of drained mushrooms and proportionate liquid OR an average of not more than 5 maggots 2 mm or longer per 100 grams of drained mushrooms and proportionate liquid.
• Mammalian Excreta in Whole Black Pepper - An average of not more than 1 mg of mammalian excreta is allowed per pound.
