This sort of screw-up is hardly unique to large-scale processing. I once bought a cookie at a local coffee shop where they hand make them from scratch on site, and it had pecan shells baked into it. Not just little pieces, but big solid ones. At least I hope it was pecan shells. Whatever it was, it was very hard, and I could have broken a tooth. Another time, a deli counter at a grocery store tried to sell me a pre-made sandwich that very clearly had 2 or 3 bites taken out of it. There was something off about one of their employees, so I guess they must've felt like a snack and then put the partially-eaten sandwich back into the display case. And another time, a member of my dining party found a large steel wool scrub pad floating in their big bowl of soup at a Chinese restaurant. The restaurant was normally very good, so I suppose it was probably some kind of relatively innocent mistake like a scrub pad falling off a shelf into the soup pot and nobody noticing. Which reminds me, there was another local grocery store where people kept getting sick, and they finally figured out a mentally disturbed employee was intentionally putting mothballs in the soup. Mistakes happen, and that's definitely not a good thing, but I'm not even convinced it's more common with larger food processing companies. Though there are some companies that seem to have a bad attitude and just don't care, Tyson being one that I'm not confident about.
