The Publix supermarket chain is not nationwide, so it would be hard to comment on the source of their meat products. You can ask the butchers there about some of the topics you read about on this forum, such as, "Is your beef grass-fed and grass-finished?" Usually, the butcher departments in my area make a big fuss over the fact that their beef is grass-fed. Markets with grain-finished beef do not advertise about it. Another thing I look for in a butcher department is whether they buy their beef whole and butcher it, versus buying primal cuts that a wholesale processor has processed. If they do their own butchering, I think I get better meat.
Eggs are trickier to buy - most say "cage-free" or "organic" but that does not mean that they are eating a natural diet and have a rooster present. I try to get my eggs from small, local farms.
