What food issues are described in chapter 14?

The industry is especially good at manipulating spoiled meat so that it does not smell or look spoiled so that it can be sold. They pump meat full of pickling chemicals to rid it of its smells. They remove the bone from a ham, along with its rotted meat, and replace it with a hot piece of iron. They stop labeling meat as One, Two, or Three Grade and instead label it all as One Grade. They use “everything of the pig except the squeal,” and they find new ways to market and sell each part.
