过去 20 年来，全球养殖鲑鱼的年产量增加了 40 倍。来自北欧、北美和智利农场的三文鱼现在全年都能以相对较低的价格买到。三文鱼养殖场因其生态影响而受到批评，但养殖三文鱼消费对人类健康的潜在风险尚未经过严格审查。通过分析来自世界各地超过 2 吨的养殖和野生鲑鱼的有机氯污染物，我们发现养殖鲑鱼中这些污染物的浓度明显高于野生鲑鱼。欧洲饲养的鲑鱼的污染物含量明显高于北美和南美饲养的鲑鱼，表明需要进一步调查污染源。风险分析表明，食用养殖的大西洋鲑鱼可能会带来健康风险，从而损害食用鱼类的有益效果。
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.
