Re: How many insect parts are found in one average can of peanut butter?

Most food products that come from farm crops are allowed to have some 
amount of insect pieces because they cannot be totally removed from the 
food.

The amount of insect pieces, stones, and other natural "defects" are 
controlled by the Food and Drug Administration.

All of the "Defect Action Levels" for regulated foods can be found at:

For peanut butter, you will find the maximum number of insect "filth" 
fragments allowed is 30 per 100 g (about 4 ounces).
