Look up the ingredients that go into wieners and bologna sometime.

COWS

Sometimes? Hot dogs & baloney are just lips and other sphincters in a casing....but not to worry-- bacteria are an excellent source of B vitamins.

[Oh, wait. I just re-read your post-- "sometime look up," not "sometimes goes into.." Never mind.]

The big thing with pigs is trichinosis. Eating animals infected with trichinosis will cause your pork to need cooking. Most of the general populace can't be trusted to cook their pork before eating it, so "animal by-product free" adds an extra layer of food safety in some people's minds. The reality is that mice and rats are huge trichinosis carriers, and there really is no guarantee that infected rat or mouse parts won't end up in hog feed no matter what type of operation it is.

Important info (just in case you're ever going to be a contestant on "Jeopardy")--Julius Caesar suffered from epilepsy- but not until after he got back from Egypt where he ate a lot of pork. He probably contacted Trichinosis there, which often forms cysts in the brain, causing seizures..... I wonder if irreverent school boys starting calling him Julius Seizure?
