Fish has always been touted as a healthy food, but when it comes to today’s farmed salmon, experts say that description couldn’t be further from the truth.

During the making of the documentary, “Fillet-Oh-Fish” by director Nicolas Daniels, an investigation among the Norwegian fjords that contain salmon farms found a layer of waste about 15 meters high, consisting of bacteria, drugs, and pesticides. And with the sea farms being situated in open water, it’s impossible to contain the pollution.

Farmed salmon has been proven to be five times more toxic than any other food product tested. In fact, Norwegian environmental activist Kurt Oddekalv claims that today’s farmed salmon is one of the most toxic foods in the world, adding that the farming of salmon is “a disaster both for the environment and for human health.”

Additionally, according to Living Traditionally, eating more than one meal of farm-raised salmon in a month can increase your risk of developing cancer in the future due to the cancer-causing chemicals and high levels of dioxins it contains. It’s also said to provide your body with higher levels of inflammation which leads to many diseases including cancer, diabetes, arthritis, coronary artery disease, and Alzheimer’s.
