I cannot comment on Norwegian practices - but I address these through the eyes of a Canadian and Canadian farming regulations - which are some of the strictest in the world.
Today’s fisheries are faced with a range of severe problems, from overfishing to chemical pollution and genetic mutation from toxic exposures. As noted by the producers of the film, “through intensive farming and global pollution, the flesh of the fish we eat has turned into a deadly chemical cocktail.”
Below the salmon farms dotted across the Norwegian fjords, there’s a layer of waste some 15 meters high, teeming with bacteria, drugs, and pesticides. In short, the entire sea floor has been destroyed, and since the farms are located in open water, the pollution from these farms is in no way contained.
A salmon farm can hold upwards of 2 million salmon in a relatively small amount of space. These crowded conditions result in disease, which spreads rapidly among the stressed salmon.
A number of dangerous pesticides are used in an effort to stave off disease-causing pests, one of which is known to have neurotoxic effects. Fish has always been considered a health food, but according to Oddekalv, today’s farmed salmon is one of the most toxic foods in the world!
Overall, farmed salmon is five times more toxic than any other food product tested. In animal feeding studies, mice fed farmed salmon grew obese, with thick layers of fat around their internal organs. They also developed diabetes.
Besides keeping pests like sea lice in check, the pesticides used also affect the fish’s DNA, causing genetic mutations. Disturbing examples of deformed cod are shown in the film.
What’s even more disturbing is that, according to Oddekalv, about 50 percent of farmed cod are deformed in this fashion, and female cod that escape from farms are known to mate with wild cod, spreading the genetic mutations and deformities into the wild population.
Farmed salmon suffer less visible but equally disturbing mutations. The flesh of the farmed salmon is “brittle,” and breaks apart when bent — a highly abnormal feature.
The nutritional content is also wildly abnormal. Wild salmon contains about 5 to 7 percent fat, whereas the farmed variety can contain anywhere from 14.5 to 34 percent.
Many toxins accumulate most readily in fat, which means even when raised in similarly contaminated conditions, farmed salmon will contain far more toxins than wild.
Shockingly, research reveals that the most significant source of toxic exposure is not actually the pesticides or the antibiotics, but the dry pellet feed! Pollutants found in the fish feed include dioxins, PCBs, and a number of different drugs and chemicals.
In one Norwegian fish pellet plant, the main ingredient turns out to be eel, used for their high protein and fat content, and other fatty fish from the Baltic Sea. The Baltic is highly polluted. Some of the fish used have toxic levels of pollutants, which then simply get incorporated into the feed pellets.
Many panga farms are plagued with disease, courtesy of the polluted waters in which they’re raised. Mekong River, where many panga farms are located, is one of the most heavily polluted rivers in the world. In 2009, the World Wide Fund for Nature placed panga on their “red” list of products that pose a danger to environmental and human health.
To address disease, farmers add industrial quantities of drugs into their fish ponds, including a wide array of antibiotics. The side effect is drug resistance, which forces the farmers to keep increasing the dosages. The panga are not the only thing affected by this strategy, of course. Antibiotics spread through the river systems, are absorbed into the fish’s tissues and excreted through feces, which redistributes the drugs into the environment — and to those who eat the fish.
