    “However, the issue of toxic chemical contamination in fish dates back decades with investigations demonstrating high levels of persistent organic pollutants (POPs), including polybrominated diphenyl ethers (PBDEs) flame retardants restricted or banned in the U.S. and U.K., polychlorinated biphenyl (PCBs), dioxin (a by-product of pesticide manufacturing), and ethoxyquin (a pesticide preservative in fish feed). The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides in local marine ecosystems has induced coastal habitat loss and increased genetic and health risks to wild marine populations. Moreover, insecticides used to kill salmon parasites (e.g., fish lice) has led to widespread disease persistence and pest resistance. Marine species biodiversity is rapidly declining due to overfishing, global warming, pathogens, and pollution. Thus, further biodiversity loss can change aquatic and terrestrial ecosystem functions and reduce ecosystem services.

    Food analysis results find the consumption of farmed salmon fillets contributes to higher rates of metabolic disorders, including diabetes and obesity. These farmed salmon also contain levels of toxins, including PCBs and dioxin, that are five times higher than levels in other tested foods. The report suggests the primary causes of farmed salmon toxicity stem from the toxicants in fish feed, like ethoxyquin, and environmental concentrations of the chemicals, whether from terrestrial sources or farmed fish itself.

    Farmed fish, like salmon, use one of the most high-risk aquaculture practices, open-net pens in coastal and offshore regions. These pens allow easy exchange of waste (i.e., feces), chemicals (i.e., pesticides and pharmaceuticals), and parasites/diseases (i.e., sea lice) between the farm and the surrounding ocean environment. The discharge of waste, chemicals, and parasites/pathogens can have a disastrous impact on marine organisms and plants, disrupting ecosystem services. Generally, these pens are in relatively remote areas, somewhat “hidden” from public view. However, these fish live in very crowded conditions, unlike wild-caught fish. The fish consume food that may contain various pharmaceuticals (e.g., antibiotics) or insecticides to control diseases and pest infestations that frequently occur in these conditions. Furthermore, the farm pens can attract predators, such as marine mammals, that can tangle and drown in fish farm nets.

    The U.S. permits the use of the pesticide ethoxyquin on fruit, vegetables, and meat meant for animal feed, with no intended uses on fish. However, fish feed manufacturing companies fail to address the use of ethoxyquin as a preservative to prevent oxidization/spoilage of fatty tissue. Farmed salmon testing reveals levels of ethoxyquin are up to 20 times higher than levels allowed in fruits, vegetables, and meats. Despite there being no intended uses of ethoxyquin on food for human consumption, the chemical can pass to humans from contaminated food sources. Although claims suggest ethoxyquin has no human health effects, scientific evidence establishes that the chemical can induce DNA damage in human lymphocyte cells and chromosome aberrations.“
