You are correct, but the difference is that companies doing that in Europe are breaking the law if they treat cattle with banned compounds, while in USA farmers do this legally and at scale. This is why in this particular case I believe that generalizing is reasonable, because the fundamental approach differs so much.
Speaking also as an European, not they would not. There's a pretty big difference in the quality of the meant across the board between shops and brands(suppliers) of meat depending how the animals were raised, fed and cared for.
Here in Austria there's been plenty of scandals covering the poor conditions of animals in meat factories (living in feces, infections with puss, etc) yet the meat cuts receive the AMA seal of approval. I also did some work for the farm tech sector and the conditions of animals in some (most) EU countries I saw were indeed as appalling as those in the stories. It almost made me go vegan.
Sure, it's all(probably) technically safe to eat due to all the antibiotics they pump in those animals, just like in the US, but quality varies a lot.
And like sibling said, there's also a big difference between the quality of fruits and vegetables you find in supermarkets depending on where they come from and the conditions under which they were farmed.
That's why I dislike these over generalist "In Europe it's like this and that" blanket statements. No it isn't, it's just one point on the graph, but in reality it varies A LOT, it's a friggin continent ffs.
