The study by Hites et al. examines the levels of organic contaminants in farmed salmon compared to wild salmon, highlighting significant differences in contaminant loads. The research analyzed over 2 metric tons of farmed and wild salmon from various regions, finding that farmed salmon, particularly those from Europe, have much higher concentrations of organochlorine contaminants than wild salmon. The study also suggests that the diet of farmed salmon, which is high in fish oils and fish meal, is a major factor in the higher contaminant levels. The human health risks associated with consuming contaminated farmed salmon are discussed, with the authors noting that the risks may outweigh the benefits of fish consumption. The study emphasizes the need for better labeling and further investigation into the sources of contamination, especially in the feeds used for farmed carnivorous species like salmon.The study by Hites et al. examines the levels of organic contaminants in farmed salmon compared to wild salmon, highlighting significant differences in contaminant loads.
