Opinion:
The above results only represent a snapshot of extraneous matter levels in the market. The insect fragments for the most part are from pests associated with flour sanitation. They are weevil, tribolium, lesser grain beetle, and flour moth. Macaroni is produced using semolina flour. Semolina is a high quality four milled from the heart of the wheat kernel. For this reason semolina flour has a history of very low insect fragment counts. Any rodent hair longer than 3 mm is generally considered to be a post-processing contamination.
