If its not something that is OK to sit on a shelf for a few months, you won't find it at a Dollar General.
When it comes to actual fresh foods (which can be found if you go to actual grocery stores), those are highly regulated. You'll find fancier varieties at fancier grocery stores, but in the end a yellow onion at Kroger is about the same as a yellow onion in Safeway or Publix or Albertsons or HEB or Whole Foods.
I think it's a combination of having them year-round (they are picked before they ripen for shipping) and the emphasis on color/look being very high. A good tomato tastes much better than most store bought to the point I didn't know I liked tomatoes until I had a garden grown one. Now I eat store bought as well but it's not the same.
I don't find most other fruits/veggies to suffer nearly as much from that though.
It isn't that homegrown tomatoes just taste better, they actually have taste.
Unfortunate that they can be a bit difficult to grow. Very weather dependent.
US does not have a problem with food safety, it has a problem with widely available UPF with many other factors (price, time, distance to fresh produce etc).

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.
