From the BBC:
McDonald's fined for bolt in meal
Fast food giant McDonald's has been fined £13,500 after a metal bolt was found in a snack at a West Midlands shopping centre. A customer chewed on the bolt, which was in a sausage and egg McMuffin, at the outlet in Merry Hill in June 2006.
The company pleaded guilty at Dudley Magistrates' Court on Thursday to a charge of producing food which did not meet required standards.
The court heard bolts were missing from a kitchen grill.
Wait for it... but aren't we supposed to get more iron in our diets? Wahey! Boom boom!
