The data does not support your thesis. US ranks 3rd in Quality and Safety of foods [1]. USDA Prime beef ribeye will have similar quality from variety of stores, USDA Choice will be similar across multiple stores as well.

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).
