What is incredibly irritating with the whole thing is that, assuming you wash up occasionally(!), it is perfectly possible to work in such a way as to prepare pig food in your kitchen without it coming into contact with any meat. And, to be honest, even if it did come into contact with the odd dirty knife it is hardly in the same league as feeding diseased sheep to cows, a practice which allegedly caused BSE, and was sanctioned by those in charge (thinking about it, I would hope meat sold for human consumpion was disease free!!). Since most of these rules tend to make it difficult to feed your pigs anything but manufactured pig food one does tend to wonder if there is not some ulterior motive involved.
