You can eat, even poisonous mushrooms can be eaten. but only once. Look. Let's say the meat passed the control and went along the chain to the store. It was transported, stored, butchered ... Maybe it even lay there for three days and at what temperature. What other life could have originated on this meat is a big question. So better heat it well.
No, I strongly discourage eating raw meat that is bought in the store. As we sometimes "pass", I imagine sanitary-hygienic and veterinary control at the border. I don't think the store is better. Those. there is no guarantee that the control was passed as it should be.
Yes and no. In theory, the products should arrive on the shelves after passing control and be absolutely safe. But, as they say, it is also written on the fence, and behind it there is firewood.
So, it is better not to do this.
