The discovery was made during a routine check of the diner's hygiene and the origin of its food items, The Local.fr reported Thursday.

Some 300 pounds of meat were discarded after the owner of the diner could not produce certificates showing the origin of the meat. The proprietor also was arrested for employing a foreigner without a work permit.
Caterpillars are a common source of protein in Africa. One method of preparation calls for thoroughly washing the dried bugs, steaming them in salted water for 10 minutes and then frying them in oil until crisp.
Serve with tomato relish.
