Lethal Virus Found in Farmed Salmon

Lethal Virus Found in Farmed Salmon
  • 1 of 2

Two companies, three salmon farms and a whole lot of uncertainty — that’s the situation in British Columbia’s salmon farming industry these days. The Canadian Food Inspection Agency (CFIA) has placed three farms under quarantine because of tests that showed evidence of the IHN (haematopoietic necrosis) virus.

While IHN is not harmful to humans, it can be particularly lethal for Atlantic salmon. Finfish such as sockeye, chinook, coho, and rainbow trout can also contract it, though wild populations have, to date, been more resistant.

According to CFIA, the virus is found in the Pacific Ocean watershed of B.C. On occasion, it has also popped up among farmed fish. It can be spread by contaminated equipment and contaminated water, as well as by infected fish, both alive and dead. A vaccine to prevent the virus is available, but the BC Salmon Farmers Association say Mainstream was not using it.

As of this writing, 30 B.C. fish farms have been cleared after being tested for the virus. “Weak positive” results have been found on two Mainstream Canada farms north of Tofino as well as on a Grieg Seafood coho farm near Sechelt. All three farms are under quarantine.

The virus has also cropped up in Washington among Atlantic salmon at a Bainbridge fish farm, leading to destruction of more than a million pounds of Atlantic salmon. In an interview with the Kitsap Sun, John Kerwin, Department of Fish and Wildlife fish health supervisor, said, “Any first time it occurs, you don’t fully understand the impact to wild fish. We know it can impact (farm) fish. If we move fast, we can try to minimize the amplification.”

So what's new the human race are always messing with nature. In England they want to cull badgers because of foot and mouth disease but the badgers caught it from the cattle in the first place by living on dirty farms that were not cleaned and disinfected properly. It is always natures fault according to humans!!!

I've found the name of a vegetable that might reduce the demand for wild salmon - purslane.
It supplies the same EPA and DHA forms of omega-3 that are found in wild salmon. Since farmed salmon often have little omega-3 in their diets (as opposed to the large amounts from their natural diets), it also seems worthwhile to try adding purslane to their diets and see if that improves their health. Not very well known as food in the US; it is often considered a weed instead in the US. More popular in Europe, where it grows wild. Sometimes available as an ingredient in mesclun salads.

Salmon fish farms need to be removed from the ocean. They are putting wild salmon at risk.

Dresia V. Fish has been contaminated for a long time, especially in the oceans around Asia, where they are highly contaminated with mercury.

To me this old news. We have been told to buy only wild salmon.
Of course anything for money, otherwise our wild fish, chicken, pork, beef and Produce would be as nature intended. No offence to vegetarians - I have two in my family and am thinking of changing my whole diet to vegetarian, but husband still ls a meat and potatoes man.
