The data on salmonella is not super solid, but points to higher levels in the U.S. https://www.bbc.com/news/uk-47440562
Well...if you stop and think about it for a second - of course it is. If our, European farmers have to abide by certain animal welfare standards and the American ones don't, then of course American meat will be cheaper. Equally, I wouldn't want to eat chicken meat from China or Vietnam - their animal standards are nowhere near ours, so why should they be sold here? If Americans improve their standards then they are welcome to our markets.
The chicken that many US commenters see as intact wings and breasts are probably higher quality than the exports (unless they go specifically to a discount store specializing in low quality foods).
Of course its gonna be mostly packaged, mass produced crap....
Well not really, especially when it comes to Beef. Pork has has a rather diverse selection from both side, but generally I think they are about the same.
Don't even get me started on trying to get unsmoked ham but that's a cultural thing.
That's a long way from "all sort of meats are worse in quality", though.
Do you have any data on rates of salmonella from chicken, specifically, in both regions?
Edit:
"Chicken, beef and pork account for just 33% of salmonella poisonings in the United States, according to the U.S. Department of Agriculture"
