 Really? Yeah. Oh, it was a colossal amount of money. Routine use of antibiotics has been gradually phased out from the early 2000s onwards. Some are still legal, but only if given by a vet and only if animals are sick, which is good news for them and for us. But while UK birds won't be given antibiotics as a matter of course, that's not the case everywhere in the world. This is what we complain about when we have imports coming in because they can still do all that if you're in Brazil or in other countries.
