I've been served a salad containing a roach before. Man, I was out of that restaurant quick!
My daughter, at age 4, got a mouthful of wired bread tie in a sandwich at another restaurant; thank God she was able to pull it from her mouth and express herself before swallowing! The manager was as horrified as we were!
Thankfully nothing in canned, boxed, or frozen food....heard too many horror stories of mice in drink cans, and so forth!
