It would be more interesting to analyse human faeces.
I wouldn't mind betting there would be alsorts of insects and insect eggs larvae rodent hair ....the list would be endless.

Ever eaten a salad and spotted a creepy crawly?
How many didn't you see? Ever shared a bowl of nibbles in a bar or at a gathering/party? Did everybody share your hygene routine in the bathroom?
Enjoy an omlette?.....
Dont worry about it.
