Swine farming generates a large amount of wastes containing various contaminants, resulting in environmental contamination and human health problems. Here we investigated the contamination profiles of antibiotics and antibiotic resistance genes (ARGs) as well as microbial community in groundwater of the two villages with or without swine farms, and then assessed the human exposure risks of antibiotics, ARGs and indicator bacteria through drinking groundwater. The results showed that swine farming could lead to enhanced concentration levels of various veterinary antibiotics and ARGs in the groundwater in comparison to the reference village without swine farming. The microbial diversity of groundwater was significantly decreased with predominance of conditional pathogens Acinetobacter (up to 90%) in some wells of the swine farming village. Meanwhile, the abundance of Acinetobacter was significantly correlated to bacterial abundance, ARGs and integrons. The local residents could ingest various antibiotic residues and ARGs as well as pathogens, with daily intake of Acinetobacter up to approximately 10 billion CFU/resident through drinking groundwater contaminated by swine farming. The findings from this study suggest potential health risks of changing gut microbial community and resistome by drinking contaminated groundwater.

养猪业增加了不动杆菌的繁殖，并增加了地下水中的抗生素抗性基因。
养猪业产生大量含有各种污染物的废物，导致环境污染和人类健康问题。在这里，我们调查了有或没有养猪场的两个村庄的地下水中抗生素和抗生素抗性基因（ARGs）以及微生物群落的污染状况，然后评估了通过饮用地下水对人类暴露于抗生素，ARGs和指示细菌的风险。结果表明，与没有进行养猪的参考村相比，养猪可以提高地下水中各种兽用抗生素和ARGs的浓度水平。在养猪场的一些水井中，由于条件病原菌占主导地位（不超过90％），地下水的微生物多样性显着降低。与此同时，不动杆菌的丰度与细菌的丰度，ARG和整联蛋白显着相关。当地居民可以摄入各种抗生素残留物，ARG和病原体，通过饮用猪场污染的地下水，每人每天摄入不动杆菌的摄入量约为100亿个CFU。这项研究的结果表明，通过饮用受污染的地下水，改变肠道微生物群落和抵抗力组可能存在健康风险。
