Man, the hotdogs had human in them. That's got to be the bare minimum of standards. "No people meat."
Also, Muslims and Hindus and Vegetarians, not to mention people with allergies have no choice but to trust labeling. Or not eat hot dogs at all, which is the smart move anyway.
Let's be real - if I'm eating a hotdog, I've already thrown in the towel with being concerned about what I'm eating.
