You're not even allowed to know which country meat comes from, let alone how it was slaughtered, or how it was treated when alive. If the seller doesn't make special claims about it, all they have to put on the packet is the last country in which a "significant process" was carried out. That could be just putting plastic wrapping on it. We are also likely to be deprived of the right to that it hasn't been pumped up with hormones, or genetically modified, all in the name of free trade.

As Leveller pointed out, if you use any animal product, eggs, milk, cheese, leather, wool, and so on, apart from naturally moulted wild wool perhaps, animals have to die. Not least because 50% of their offspring are male and therefore useless unless killed young. Agriculture would quickly become impossible if the surplus males were allowed to roam about, fighting for leadership and disrupting the herds, and selective breeding would be undone within a very few generations.
