One of my favorite Patriotic Plant posters cries out “Not even good enough for a dog!” In the Plant, any food that touches the floor can’t be sold for human consumption. There’s no five-second rule at work either; if it hits the floor, it goes in the INEDIBLE bin. But this contaminated food is sold to pet food processors who aren’t subject to the same restriction. Under the razor-thin margins of chicken plant economics, this secondary product stream can be an important source of revenue. The purpose of the poster, which shows a forlorn-looking dog eying up a bowl full of rusty parts and old gloves, is not to contaminate the contaminated product stream with stuff that’s really inedible.
