I don't know what grocery stores are like where you live, but where I live, raw meat comes pre-packaged in plastic, and it is conventional to put it in a 2nd plastic bag before it is bagged with other groceries. Also, I don't know where you live, but it's generally a good idea to wash raw fruits and vegetables before you eat them, whether or not you put them in bags that also contain meat. For all of those reasons and more, I would not bother washing grocery bags.
