The Food and Drug Administration says that there is a recall for more than 260,000 cases of shredded cheese sold in 31 states and Puerto Rico because of potential metal fragment contamination.
I’m not saying that would never happen, because I’m sure it has. However, most places would have a spare metal detector unit just in case this type of thing happened.
What is probably more likely is that the factory did not have a very frequent test cycle for their metal detector. Which means, the metal detector could have been broken for a long time and nobody noticed it. Given enough time, something is going to happen and the product could have become contaminated with metal shavings.
Until the detectors break and management just says keep going until that part shows up.
