Hot dogs are gross. I have never found them to be appetizing. The old myths of the hot dog being made of ground parts of the animal that cannot be sold because they are scraps is true! lol They are disgusting and they make you fat and filled with parts that you wouldn't eat before they were ground up. Also, I think the parts of the animal that can possibly be a portion where some of it was infected will certainly be put into the grind meet. I took a health class in high school where it focused on the meet production and found out a lot about what is actually in our food.
There are some hot dogs that claim to use certain meats which make them higher in price. I would suggest eating those if you want to eat hot dogs at all.
