The Oregon Department of Fish and Wildlife has reported that several dogs were sickened by salmon poisoning in the Newport area. Salmon poisoning disease (fish disease) is a potentially fatal condition seen in dogs who have ingested certain types of raw fish found in the Pacific Northwest from San Francisco to the coast of Alaska. It is most prevalent from northern California to the Puget Sound. It is also seen inland along the rivers of fish migration.
Salmon, trout, and other fish such as the lamprey, sculpin, redside shiner, shad, sturgeon, candlefish and the large-scale sucker who spend their lives in coastal streams and rivers in the Pacific Northwest can be infected with the organism Neorickettsia helmonthoeca.
Symptoms To Watch For
If not treated, salmon poisoning disease is usually fatal within 2 weeks after exposure. The symptoms of salmon poisoning disease are similar to other gastrointestinal diseases such as canine parvovirus. If infected, your dog would likely show some or all of the following symptoms about 6 to 10 days after ingesting fish which were carrying the bacteria. Symptoms may be of variable severity but generally consist of:
* Fever, often greater than 104 F
* Depression
* Anorexia
* Vomiting
* Diarrhea
* Nasal or eye discharge
* Weight loss
If you know your dog has ingested raw fish and it exhibits any of the symptoms listed above, notify your veterinarian immediately. If identified in time, salmon poisoning disease is treatable. A helpful part of the diagnosis is telling your veterinarian that your dog ate raw fish, even if you only suspect that may be the case.
Prevention
* Control what your dog eats while on fishing trips.
* Leash your dog at the beach or river so that you can monitor its activities.
* Wrap garbage, especially fish entrails, and dispose in well-secured cans.
* Don't feed raw fish to your dog. Cook fish thoroughly or deep-freeze it for a minimum of 2 weeks to destroy the parasite before feeding it to your dog.
