I don't know that I would trust feeding raw meat from the grocery store. This meat has gone thru some pretty nasty, dirty slaughter houses and extremely unsanitary procedures/practices, before it gets packaged. Cooking it shouldn't be a problem, but raw??? - no way I'd chance it. Some of the pieces that have aired on t.v. about slaughter houses and the meat that come out of them, is enough to make you sick just watching it - never mind actually eating it!
