dogs don't usually get food borne illness unless they're immune compromised or have intestinal problems already. As for parasites, that's why I don't feed my dogs pork, but other than that,at least if you live in the US, the beef at least is 99% guaranteed to be free of parasites, otherwise nobody would be safe. Basically, if a human wanted to, he could eat fresh raw beef as long as it wasn't ground, and be moderately assured that they won't be hurt by it. On top of that, the heartworm prevantitive all dogs should be getting also usually covers most food borne parasites
