Surprisingly enough, they hold most beef processing plants to higher standards than the rest of the industry (they're still buying cheap trimmings, don't get me wrong), because they do so much volume, basic probability tells us that most food poisoning outbreaks would hit them otherwise.
Sure, you could find a farmer that raises cows and butchers them on site, but that's rare, and the easiest way to actually achieve that is to buy a whole or half cow at a time.
Most small farms don't bother with that: they raise it from calf to adult on grazing land, then send it to a feed lot where the miracles of modern science significantly increase the cow's weight before slaughter. Cows that are still producing calves get retained to grow the herd next year.
If you want to pay extra for this, look for "grass-fed, grain-finished" beef. Most unlabeled stuff in the US goes through that funnel though.
So they developed standards and demanded that all their hamburgers be formed, frozen, and packaged by the processor and kept frozen until cooking. It's really the safest way to handle that volume of ground beef through the distribution chain.
Apparently their 1/4 lb burgers now use fresh beef, not frozen. Not sure how that's handled but it sounds more risky.
Perhaps you're anticipating this:

There are farmers everywhere who will sell you a cow. There are small butcher shops that will process it.
This is a solution in search of a problem, in my opinion. It will only benefit already massive corporation farms.
I'm all for breaking the stranglehold of those big 4 meatpacking companies, but make it an actual law, not something that won't hold up in court.
