A California start-up called Clear Food has done the Thing That Should Not Be Done: analyzed what's actually in a bunch of different hot dogs. They took samples from 345 different hot dogs and sausages, and as you might be able to guess, the results weren't that "these hot dogs were made from grade A organic meat that's raised in conditions so great, the animals have higher thread-count sheets than you." In fact, 15% of the samples had "evidence of meats not on the labels." This includes pork products in sausages that are supposed to be chicken or beef, as well as animal products in dogs that were supposed to be vegetarian. And this on the same day that the World Health Organization tells us bacon causes cancer.
