“Consumption by dogs of raw or undercooked salmon from California, Oregon, and Washington can lead to canine death within 7 to 15 days. This is caused by a naturally occurring bacteria, and not by improper handling by fish houses or from an environmental catastrophe.”

“Salmon Poisoning Disease only occurs in the Pacific Northwest because the host snail only lives in the Pacific Northwest. The Oxytrema silicula snail is only found in coastal streams and rivers of northern California, Oregon, and Washington. However, salmon can be found in the ocean outside of this region with the Salmon Poisoning Disease fluke. Salmon can be infected with this fluke at a young age then carry the fluke in its tissue when it migrates to the ocean, therefore, an adult salmon caught in the Pacific Ocean could be a carrier.”

“Most fish used in canned pet foods comes from the decaying leftovers of the seafood industry around the world. It is a mishmash that’s high in phosphorus and magnesium, which can be a serious problem in cats with a history of urinary tract disorders or kidney disease. In practice, I have seen many cats develop urinary tract infections and blockages if they eat fish — even canned tuna. After I shared one meal of halibut with my three cats, within hours two of them had urinary tract flare-ups, and by 6 a.m. I had my boy kitty on the surgery table while I inserted a catheter. It’s even worse if, as is most common, the fish are simply ground up, bones and all. Excess phosphorus is dangerous for kitties with kidney disfunction; there is as much phosphorus as calcium in bones.”

“Whatever combination of evolution and human intelligence produced modern chickens, pigs, and cows, there is no evidence that eating fish was part of their design. In fact, menhaden products offer no real benefit to chickens or chicken producers, they have already lost much of their small share of the poultry feed market to soybeans.”
