Butchery has required extensive regulation since the Egyptians. It is quick and easy to kill everyone near and dear to you without skill & knowledge. The entire judeo-christian-islamic faith movement is based on dietary regulation, much of it still relevant.
Conflating 'markets' with the precautions on meat is not reasonable, imo. I did not see a single faq regarding produce, or milk, or cheese. I will revisit once I have a kbd.
