Are there bugs in peanut butter? No, ONLY insect fragments.

peanut butter jar containing insect parts

Ever heard that there’s a certain number of bugs in a particular food? One of the more unusual claims along these lines is that there are bugs in peanut butter. Given the number of peanut butter and jelly sandwiches (PB&Js) that many of us ate as kids, if this claim is accurate, we’ve likely eaten quite a few bugs over years just by consuming peanut butter.

Why would there be bugs in peanut butter?

It turns out, there are bugs in American peanut butter because the FDA allows it and companies save money by not tossing out peanut butter that tests ‘positive’ for insect parts but remains within the FDA’s generous limit of 30 parts of ‘insect filth’ for every 100 grams of peanut butter.

The FDA’s “Foods Defect Handbook” section “AOAC 968.35” states that an “Average of 30 or more insect fragments per 100 grams” is permissible in peanut butter. If you really want to be grossed out, scroll the “Foods Defect Handbook” for other allowable food contaminants. Or keep reading this article to learn what else is allowed in your peanut butter.

  • FDA’s bug parts and rodent hair thresholds are maximum thresholds
  • Small amounts of larvae and bug eggs are also unavoidable in food
  • Food scientists explain some of the seemingly generous FDA insect allowances for different foods.

    Does organic peanut butter have insects in it too?

    The FDA’s “Food Defect Handbook” pertains to organic foods too. So, organic peanut butter is also allowed the same amount of insect parts and rodent hair as non-organic peanut butter, which is an average of 30 parts of ‘insect filth’ and one rodent hair per 100 grams of peanut butter.

    Gross. Did you say rodent hair? What else does the FDA allow peanut butter to contain?

    In addition to allowing some insect parts in your peanut butter, the FDA also allows one rodent hair per 100 grams of peanut butter. The FDA’s “Foods Defect Handbook” section “AOAC 968.35” states that an “Average of 1 or more rodent hair per 100 grams” is permissible in peanut butter. I

    ‘m not sure what the FDA means by an average of one or more here. It seems they should word it as “a maximum average of one rodent hair per…” but maybe they have a reason for it. From what I could tell, the FDA intends one rodent hair per 100 grams of peanut butter to be the maximum average (meaning no more than one hair) but their literature’s wording seems to allow for more than one rodent hair per 100 grams of peanut butter.

    Here’s how peanut butter is made industrially

    Here’s a video of how peanut butter is processed industrially. I can see how, given the scale of this operation, some small amount of insect parts can end up in the finished product. I’m less sold on how rodent hairs could feasibly end up in peanut butter without there being a rodent infestation in the peanut butter factory? If anyone has ideas about how rodent hairs end up in peanut butter during processing, put them in the comments.

    It seems to me that the most likely place where insect parts or rodent hairs could get introduced into peanut butter is when all the ingredients are mixed up and blended in a vat. It seems possible for bugs or an occasional mouse or rat to fall in, get ground up with the peanuts, mixed with the oils, and end up in your food.

    How do food processing plants keep bugs and rodents out of peanut butter?

    Food processing plants implement many pest control measures, depending slightly upon the food they process. Generally, they’ll have the following:

    • Door blowers that pull air out of the facility to prevent insects from flying in
    • mouse traps checked daily
    • UV light systems to exterminate insects that sneak into the facility
    • Sanitation department
