The annual global production of farmed salmon has increased by a factor of 40 during the past two decades. Salmon from farms in northern Europe, North America, and Chile are now available widely year-round at relatively low prices. Salmon farms have been criticized for their ecological effects, but the potential human health risks of farmed salmon consumption have not been examined rigorously. Having analyzed over 2 metric tons of farmed and wild salmon from around the world for organochlorine contaminants, we show that concentrations of these contaminants are significantly higher in farmed salmon than in wild. European-raised salmon have significantly greater contaminant loads than those raised in North and South America, indicating the need for further investigation into the sources of contamination. Risk analysis indicates that consumption of farmed Atlantic salmon may pose health risks that detract from the beneficial effects of fish consumption.
在过去二十年中，全球养殖三文鱼的年产量增长了40倍。来自北欧、北美和智利养殖场的三文鱼如今全年都能以相对较低的价格广泛供应。三文鱼养殖场因其对生态的影响而受到批评，但食用养殖三文鱼对人类健康的潜在风险尚未得到严格审查。在分析了来自世界各地的2公吨以上养殖三文鱼和野生三文鱼的有机氯污染物后，我们发现这些污染物在养殖三文鱼中的浓度显著高于野生三文鱼。欧洲养殖的三文鱼污染物含量明显高于在北美和南美养殖的三文鱼，这表明有必要进一步调查污染来源。风险分析表明，食用养殖大西洋三文鱼可能带来健康风险，这抵消了食用鱼类的有益影响。
