Not Just Soylent Green

You remember the last line from Soylent Green?  Oct. 23, 2015 Yahoo Health reports on an analysis of hot dogs.  Many of the "vegetarian" ones contained meat, and some of the pork-free ones used to squeal.  Worse:

Even grosser: 2 percent of all samples were found to have traces of human DNA in them. Veggie dogs were the worst off, accounting for 67 percent of the hygiene issues and two-thirds of the human DNA found.

 I am not suggesting that someone is slaughtering people or that workers in the factories are short a few fingers. This is likely hair, fingernail clippings, etc.  But if you think diseases spread across species too easily, imagine within species.
