虽然出口导向型虾类养殖已成为发展中国家许多小规模养殖户的重要收入来源，但产品在发达国家港口的拒收率仍然很高，主要原因是抗生素的过度使用。为了揭示抗生素滥用的原因，我们于2015年采访了越南201名虾农，并从每户池塘采集虾样本进行药物残留筛查。这些测试显示，40名农民的样本中发现残留药物超过日本标准可接受的限度。我们进行了横截面 Logit 和 Tobit 回归，以检验残留测试的结果是否与农民的特征和管理实践显着相关。本研究发现：（1）接受BMP培训对减少药物残留有显着且积极的作用； （2）如果农民认识多个推广人员，这些关系对减少残留药物有显着的积极作用； (3)有过虾病爆发经验的养殖户减少抗生素的使用。总体而言，本研究有助于从多个（社会、经济和心理）维度揭示对虾养殖中兽药残留检测的决定因素。
While export-oriented shrimp farming has become an important source of income for many small-scale farmers in developing countries, the rate at which products are rejected at the ports of developed countries has remained high mainly due to the overuse of antibiotics. To reveal what determines the overuse of antibiotics, we interviewed 201 shrimp farmers in Viet Nam in 2015 and collected shrimp samples from each household’s pond for the screening of residual drugs. These tests revealed that residual drugs exceeding acceptable limits by Japanese standards were found in the samples of 40 farmers. We conducted cross-sectional Logit and Tobit regressions to examine whether results of the residue tests are significantly associated with farmers’ characteristics and management practices. This study finds that: (1) receiving BMP training has a significant and positive effect on reducing residual drugs; (2) if farmers know multiple extension officers, these relationships have significant and positive effects on reducing residual drugs; and (3) farmers with experience of shrimp disease outbreaks reduce use of antibiotics. Overall, this study contributes to revealing the determinants of detecting veterinary drug residues in shrimp farming in multiple (social, economic and psychological) dimensions.
