Canadian Government Cover-Up Threatens Your Health, and the Entire Ecosystem

In British Columbia, pacific salmon are an essential species for the ecosystem. They fill hundreds of streams and rivers, feeding hundreds of species, including humans. Since the early 1990’s, salmon numbers have rapidly dwindled, coinciding with the introduction of farmed salmon pens.
Fish farms breed pathogens that can spread like wildfire and contaminate any wild fish swimming past. Wild salmon that died before spawning have tested positive for a number of salmon viruses, including the highly lethal “salmon influenza”.
Farmed fish, purchased in stores around British Columbia have tested positive for at least three lethal fish viruses, including the dreaded ISA virus (aka salmon flu), salmon alpha viruses, and Piscine reovirus, which causes the salmon to have a heart attack, preventing them from swimming upriver.
Dr Mercola recommends buying locally-grown foods, and wild fish only. Fish farms are a breeding ground for disease and toxic waste, and produce fish of inferior quality. Due to the dramatically increased disease risk—a natural side effect of crowding—these animals are further contaminated with drugs, and in the case of salmon, synthetic astaxanthin, which is made from petrochemicals that are not approved for human consumption.
