Cooking kills worms. The only thing it won't kill (AFAIK) is prion disease. Rabies, apparently, is also possibly killed by cooking (or maybe it's something else involved in consumption).

When I was a vet tech in the Air Force, someone told me they'd been working in an AF vet clinic in the Philippines. Someone brought in a dead dog they were sure had had rabies. The vet and the techs went in another room, and when they went back to the dog, it was gone. Well... it WAS meat. Given that there was a lot of rabies in dogs, and people ate dogs, and nobody had ever developed rabies from eating a dog, I came to the conclusion that cooking kills the rabies rhabdovirus. I didn't really look into it, though, as I wasn't planning on eating any rabid rover roasts anytime soon.
