And you think there’s no acceptable amounts of rat poop in any other food you eat? Funny.

Chickens aren’t grown in sterile level 4 labs. There’s all kinds of contaminants in every food you eat. Many many more so if you buy “organic” because those fertilisers and weed killers are far less pure.

There are exceptions, of course. But you’ll still find miniscule trace amounts of quicksilver in baby food every once in a while, sure. So little that the check machines won’t even register there’s any at all but a lab could still find some. But by and large, there are acceptable levels for everything and we check for all of that, too. There’s a reason it’s an industry, not grabbing a random chicken from the street and biting it’s head off.

Yep, you eat rat poop.

And probably feathers and beak, too.

But the baby chick macerator drops the fluffy goo into a different bucket. It’s not even necessarily the same processing plant as where the adult chickens are slaughtered for meat. Freshly hatched chicks are sexed so the boys can be immediately culled. Other meat doesn’t go into that macerator, so you’d have to go out of your way to add it to the nugget mix, and the benfit of a few extra lbs of mostly feathers and bone are not going to be worth the effort.
