Like I said, you're lucky if you can get away with it up there, but I didn't want anyone else who might read that to think it was OK to even have a dog around cleaning fish. Just licking any of the blood is enough to make them very sick, and die without treatment.
It's only a problem in dogs, not cats, and it's only a problem with raw fish, not cooked. But it's not something to mess around with :~\
I've been following your conversation about feeding raw salmon to dogs. When we moved to Alaska years ago, I learned that what my father told me was true....that Alaskans feed raw salmon to their dogs and the dogs thrive on it and do not get sick. I found that to be amazing as we suffered the tragic loss of a golden retriever when we lived in the Northwest. My husband and a friend were cleaning salmon in our driveway and somehow, one of our beloved golden retrievers got ahold of either a small piece or perhaps licked up some blood.
She became very sick and our vet was the one who figured out what was wrong with her...that she had eaten some raw salmon. The parasites in raw salmon laid eggs (fluke eggs) in her internal organ (liver?). Well, in spite of the best medical care in the doggy hospital, she died.
When I asked our vet why it is that dogs in Alaska do not get sick, he thought that perhaps it is because the dogs are fed salmon from the time they are pups and they could develop an immunity of sorts to the parasites. Or, that our salmon up here does not have these parasites.
I'll have to go read up on the links you posted, HairOfTheDog.
Anybody that's a fish keeper would be horrified at the thought of sushi anything. Fish come down with stuff that thinks penacillin is a snack. For example piscine pseudomonas is one vile and nasty bug. Psuedomonas in general is some bad news. Piscine tuberculosis is another bad bug. It makes antibiotic resistant TB in people look like a 95 pound weakling going up against Mike Tyson. Fish also carry some pretty nasty parasites too (that need another species to complete the cycle). I don't want to be an alarmist, but porcine trichinosis is the sniffles in comparison (that being some pretty nasty stuff in its own right). There's a big problem with that in Mexico.
The problem with trich is that it depends where the larvae germinate, e.g., brain tissue. This leads to some really interesting sympoms.
