Earlier quoted context omitted.
Empirically, Giant Eagle (the crap chain supermarket in PA) beef tastes like crap, and local butcher beef tastes really good. Locality is a good proxy for people caring about food tasting good, and for not going through enormous horrible disease-ridden meat-packing plants. The latter tends to produce meat that tastes bad and periodically makes you sick.
AFAIK, there are only 4 cattle slaughterhouses in PA: http://www.aphis.usda.gov/import_export/downloads/slaughter_... Only one of the 4 is not owned by Cargill or JBS. Unless your beef vendor is taking delivery on whole carcasses and then packing it themselves, the beef is probably packed at the slaughterhouse, as well.
But really, I don't know if the goodness in non-Giant-Eagle meat has anything to do with the meat packing industry. I just was trying to convince ars that food people aren't being totally dumb when they say that local is often better than GEagle equivalents.
