Speaking of pickles, I briefly worked for one of the major pickle makers and what went on there has had me sworn off their products for 38 years. I have no doubt the same went on in the other makers but I didn't work there so don't know for sure.
As for "parts is parts", growing up we used about every part of the cow or pig for something. I didn't care much for brains, organs, nor tripe but the rest of it wasn't bad. Tongue was the surprise for me, it reminded me of dry roast beef without the stringiness. Made into sandwiches with mayo and horseradish it was quite tasty.
