Remember my dad mentioned these from time to time. Also I heard that local slaughterhouse staff were not allowed to tell when there was an emergency job as otherwise everyone would gather to see what this cow had eaten. (As mentioned nails and screws were common but i heard about one of them, not ours, eating a bunch of huge galvanized bolts. Investigation found out they were left behind by high voltage powerline technicians I think.)
