Please read the important notice below from our state Veterinarian Dr. Emilio Debess regarding dogs getting salmon poisoning:
After several dogs were sickened from salmon poisoning around Newport, Oregon authorities warned people to keep pets away from dead fish on Thursday.
According to the Oregon Department of Fish and Wildlife, salmon and trout carcasses may harbor the bacteria Neorickettsia helminthoeca in their blood which can kill dogs without treatment. The bacteria is transmitted through a parasitic flatworm or “fluke” and can infect a dog after it eats, bites or even licks an infected fish carcass.
The highest risk of salmon poisoning is usually in September when salmon gather in rivers to spawn and die, so cases early in the year are unusual, according to ODFW.
Pet owners are advised to keep their dogs on a leash and in sight to keep them away from fish carcasses. People are asked to collect and bag up all garbage associated with cleaning fish and to clean coolers and gear.
According to ODFW, the highest risk of salmon poisoning is usually in September when salmon gather in rivers to spawn and die, so cases early in the year are unusual.
Symptoms may begin five to seven days after exposure, which can include severe vomiting and diarrhea.
What are the clinical signs of salmon poisoning?
Signs of salmon poisoning are typically seen within a week of the dog eating infected raw or undercooked fish or salamanders. Common signs include lack of appetite, vomiting, diarrhea (which may include blood), fever, weakness, enlarged lymph nodes, weight loss, discharge from the eyes or nose, increased respiratory rate, increased heart rate, muscle tremors, and seizures. If the infection is not treated, most dogs will die within two weeks. Fortunately, treatment significantly improves the chances of survival.
Treatment of choice is doxycycline(10 mg/kg, twice daily for 7 days
Animals usually succumb because of dehydration, electrolyte and acid-base imbalances, and anemia. Therefore, general supportive therapy to maintain hydration and acid-base balance, while meeting nutritional requirements and controlling diarrhea, is often essential. Judicious use of whole blood transfusions may be helpful.
Currently, the only means of prevention is to restrict the ingestion of uncooked salmon, trout, steelhead, and similar freshwater fish.
