I have just posted this question on the test forum but realise that I may not get much of a response there so posted it here also.
I know that you cannot feed pigs any food that has come from the kitchen or even passed through it. Can you get veg from the supermarket and prepare it somewhere other than the kitchen e.g. shed, garage, workshop, and then use the veg for the kitchen and scraps/peelings for the pigs?
