Our FSA does not say anything that suggests our product is inferior quality. Yes, hormones are used in a minority share of Australia's beef (40%) because they're safe and effective. Yes, sow stalls are used because they're safe and effective (also necessary to reduce piglet mortality rates).
I'm personally opposed to mulesing and high concentration battery hen farms, I think they're cruel and unnecessary. I also oppose the live meat export trade. But none of this changes the fact that the quality of our meat is not only high, but high enough to meet EU standards.
If the UK wants to import some of our lower quality stuff, that's the UK's choice. After all, dumping EU standards was one of the reasons for Brexit, wasn't it? That's what the British people wanted, so that's what they're getting.
