Apparently, the cows (these are milk cows at the end of their useful life) are conveyed in on a belt where they cannot see what is happening to the cows in front of them. If they become aware they produce hormones that are bad for the final product. Anyway here they come down the gangway (you can imagine some ehuge industrial building with dwarves banging hammers in the background and huge pots of flaming stuff) where something is shot through their brain. They are then dumped, whole, into the processing vat where they are liquified and heated to some kiln-like temperature as if they were clay pots being fired, or iron ingots bing forged. Hair, guts, fecal matter, brains, nervous system, the whole kit and kaboodle. Some gelatinous filler is added so it will all stick together in the end, the end being about 25% meat or so. (Does high heat deactivate prions?) Well, it certainly sounds efficient. But I will never eat there again, healthy food or no. Urban legend? I cannot say but he swears by it. Good god.
