中国波阳湖附近的密集畜牧业通过粪肥将抗生素抗药性和重金属传播到土壤中,增加健康风险。 Intensive animal farming near China's Poyang Lake spreads antibiotic resistance and heavy metals into soil via manure, increasing health risks.

一项新研究发现,在中国波阳湖附近密集养猪和养鸡正在将抗生素抗药性基因(ARGs)和重金属传播到农用土壤中。 Intensive pig and chicken farming near China's Poyang Lake is spreading antibiotic resistance genes (ARGs) and heavy metals into agricultural soils, a new study finds. 尽管被标为低风险，但干家禽粪便使ARG健康风险增加了超过16,000倍，四环素和磺胺类的耐药基因显著上升。 Despite being labeled low-risk, dried poultry manure increased ARG health risks by over 16,000 times, with resistance genes for tetracycline and sulfonamides rising sharply. 用于动物饲料的锌和铜等重金属通过促进移动遗传元素,而不是直接产生抗药性,使基因转移恶化。 Heavy metals like zinc and copper, used in animal feed, worsened gene transfer by boosting mobile genetic elements, not by causing resistance directly. 细菌群Firmicutes是其中一个关键的载体. The bacterial group Firmicutes was a key carrier. 调查结果对食品作物加工肥料的安全提出了挑战,呼吁采用更好的处理方法和对动物饲料中的抗生素和金属进行更严格的控制。 The findings challenge the safety of processed manure on food crops and call for better treatment methods and stricter controls on antibiotics and metals in animal feed.
