I found this in the K9 Kitchen Yahoo group, and thought it may be of some interest!
Salmon Poisoning in Dogs
The fluke Nanophyetus salmincola is host to a rickettsia (a microorganism)called Neorickettsia helminthoeca that can cause a disease commonly known assalmon poisoning disease (SPD). The organism develops in snails (Oxytremaplicifer), infect and develop into cysts in fish, are ingested by dogs wherethey infect the intestinal tract. The dogs excrete eggs in their stool, theorganism reenters the water, infects snails and the cycle begins again.
SNAIL ==> FISH ===> DOG ===> SNAIL
This microorganism is found in salmon, steelhead, trout, Pacific giantsalamanders and fresh water fish found in and around the Pacific Ocean fromNorthern California to Seattle. The geographical limitations are likely causedby the limited habitats of infected snails.The onset of symptoms is usually sudden, usually 5-7 days after ingestionbut can be delayed up to a month. Symptoms last for 7-10 days and can be fatalin a majority (up to 90%)of untreated dogs. The dog's temperature can peaksuddenly and then return to normal or even below normal. There can be severeand bloody diarrhea, dehydration, severe weight loss and complete loss ofappetite. Symptoms can look like parvo or distemper. Diagnosis is made byfinding fluke eggs in the stool.Death is generally caused by the toll the symptoms take on the dog's body.These include electrolyte imbalance, anemia and dehydration. Treatmentsinclude hydration and nutrition, blood transfusions as well as antibiotics andrelated medications prescribed by a veterinarian. Dogs that have been infected and recovered can develop an immunity.This potentially fatal disease can be prevented by not feeding raw orpartially cooked (possibly even cold-smoked) fish to your dog. Since fish canalso have tiny bones that can become lodged in your dog's throat or intestinal tract, it may be best to avoid fresh fish altogether.
