„A dead cow or sheep lying in a pasture is recognised as carrion. The same sort of a carcass dressed and hung up in a butcher's stall passes as food! Careful microscopic examination may show little or no difference between the fence corner carcass and the butcher shop carcass. Both are swarming with colon germs and redolent with putrefaction.“
— John Harvey Kellogg
