Those folks would have died about taking a class I took -- and was required for my BS in animal science and by the pre-vet program at the university I attended -- about a thousand years ago. It was entitled meat science. We learned where the cuts of various meats came from, how to grade carcasses, food safety, etc....all hands on. Yep. We were responsible for dropping and processing cattle, sheep and hogs in a on-campus USDA facility that sold the resulting products to the university and the general public. You were not allowed to opt out. I have not looked to see if my alma mater still offers that class.
