As this page says, it depends quite a bit on where the oil is from. It’s easy enough (if a bit expensive) to find great oil from small producers.
That's an hilarious statement given the horse meat scandal.
As you say, it was a scandal and we did not accept it.
That's a fair point. Although I feel like if the same thing happened in the states, head would roll just for the fact a lot of people see horses as pets, not cattle. It would be akin to people learning they've been fed dog meat against their will. I would literally expect people to get murdered over that.
