Which is still better than their chicken--look at the frequency of the presence of campylobacter in raw chicken in the UK. It's absurd to think that they're doing anything better.
We’re vaccinating our chickens. That seems better - we get to eat raw eggs. We also seem to be doing animal welfare better [1]. It seems that the US has essentially no animal welfare regulation for poultry [2].
> In the USA, there are currently no federal regulations to control or safeguard the welfare of animals used in agriculture. An Animal Welfare Act is in place but it applies only to animals kept for non-farming purposes. State laws govern animal welfare in some parts of the country but currently no such legislation applies to poultry in any of the three major poultry-producing states considered here (Georgia, Alabama and Arkansas).
The noises from the UK are that it won't [0]. But in reality let's see.
We won't really know what happens until the ink has dried on the trade deal with the US and it has been published.
> The UK will not lower food standards to secure a post-Brexit trade deal with the US, the government says.
