Wenchy, the packaged frozen might have some additives, where I would assume (though not sure) that fresh would be free of those additives. You'd have to look at ingredients to be sure, or check with your butcher.
I get ground turkey at it is 93% lean, like the beef I usually get, but I buy it fresh. It was 2 for 1 at the store in comparison to the ground beef (Because it was on sale)
