This is pretty much the same argument I see when people are trying to discourage us from drinking raw milk. Salmonella, disease, dirty cows, all sorts of scary stories. Now that commercial milk is pasteurized, they don't care if some bad germs get in there, because it will be killed by pasteurization. Brings the standard of cleanliness down if there are "corrections" for dirty milk. Folks who produce raw milk are very cognizant of that. We who drink it are just glad to be able to get it, despite the best efforts of "big brother".
