Dog owners in northern California are reminded to take precautions to protect their pets from Salmon Poisoning Disease. Salmon Poisoning Disease is a potentially fatal condition seen only in dogs after they eat certain types of raw or cold smoked fish like trout and salmon that are infected with a bacteria-like organism, Neorickettsia helminthoeca, which is transmitted by the parasitic flatworm (or “fluke”) Nanophyetes salmincola.
