It’s easy to avoid any product you don’t wish to eat - read the label. I only buy Scottish meat and as far as possible, I buy locally produced meat. It’s a bit more expensive but we now go days without eating any meat at all, so it balances out.
I did get caught out with a local butcher, though, which is why reading the label or asking questions is important. I bought some bacon and when I got home, found it was Dutch. I was quite cross about that, even though it was my own fault for not checking, because it’s a much-eulogised local business who I assumed would only sell Scottish/British produce.
