The residual levels of antibiotics in Vietnamese eggs were monitored from 2014 to 2015. A total of 111 egg packages, distributed by 11 different companies, were collected from supermarkets in Ho Chi Minh City and the levels of 28 antibiotics were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) screening method. Sixteen samples tested positive for antibiotics; a total of eight compounds (enrofloxacin, ciprofloxacin, norfloxacin, sulfadimethoxine, sulfamethazine, sulfamonomethoxine, tilmicosin and trimethoprim) were detected. Enrofloxacin was detected in eight samples, with two samples exhibiting concentrations exceeding 1,000 µg kg. Tilmicosin was detected in three samples at a range of 49-568 µg kg. We observed that two of the 11 companies frequently sold antibiotic-contaminated eggs (detection rates of 56 and 60%), suggesting that a number of companies do not regulate the use of antibiotics in egg-laying hens. Our findings indicate that livestock farmers require instruction regarding antibiotic use and that continual antibiotic monitoring is essential in Vietnam.
2014年至2015年期间对越南鸡蛋中的抗生素残留水平进行了监测。从胡志明市的超市收集了由11家不同公司分销的总共111包鸡蛋，并使用液相色谱-串联质谱（LC-MS/MS）筛查方法分析了28种抗生素的水平。16个样本的抗生素检测呈阳性；共检测到8种化合物（恩诺沙星、环丙沙星、诺氟沙星、磺胺二甲氧嘧啶、磺胺甲嘧啶、磺胺间甲氧嘧啶、替米考星和甲氧苄啶）。在8个样本中检测到恩诺沙星，其中2个样本的浓度超过1000 μg/kg。在3个样本中检测到替米考星，浓度范围为49 - 568 μg/kg。我们观察到11家公司中有2家经常销售受抗生素污染的鸡蛋（检出率分别为56%和60%），这表明一些公司没有对产蛋母鸡的抗生素使用进行规范。我们的研究结果表明，养殖户需要接受抗生素使用方面的指导，并且在越南持续进行抗生素监测至关重要。
