The poultry industry plays a key role in developing socio-economic and health sectors in Bangladesh. Poultry waste is a potential environmental threat as untreated poultry waste is used in vegetable gardens. The study aimed to investigate the current situation of small-scale poultry farms and their waste management practices in selected areas of Bangladesh and detect and in vegetables from farms using untreated poultry waste as fertilizer.
A structured questionnaire-based survey was conducted in 86 small-scale poultry farms from different upazilas of Mymensingh and Khulna districts. 104 samples, including vegetables, poultry litter, water, and soil, were collected from vegetable gardens, ponds, fields, and wet markets in Mymensingh district to detect microbial contamination. Bacteria were identified based on their growth and colony morphology on selective media and motility tests. The presence of and was confirmed by polymerase chain reaction (PCR) using a commercial PCR kit.
The survey revealed that mostly middle-aged males were involved in poultry farming. Most of the farmers had primary education and engaged in farming for about 5 years without training. In the study area, 37% of farmers collected droppings daily in the morning and used them as organic fertilizer. About 58% of farmers did not know the hygienic handlings of droppings and faced health problems. In PCR, either or or both were confirmed in vegetables, litter, soil, and pond water.
Appropriate poultry waste management practices can reduce the possible contamination of microbial agents in the human food chain.
家禽产业在孟加拉国社会经济和卫生部门发展中发挥着关键作用。家禽粪便若未经处理就用于菜园，会对环境构成潜在威胁。本研究旨在调查孟加拉国选定地区小型家禽养殖场的现状及其粪便管理做法，并检测使用未经处理的家禽粪便作为肥料的农场蔬菜中的[具体微生物名称1]和[具体微生物名称2]。
在迈门辛和库尔纳地区不同乌帕齐拉的86个小型家禽养殖场开展了一项基于结构化问卷的调查。从迈门辛地区的菜园、池塘、田地和湿货市场采集了104份样本，包括蔬菜、家禽粪便、水和土壤，以检测微生物污染。根据细菌在选择性培养基上的生长情况、菌落形态和运动性试验对细菌进行鉴定。使用商用PCR试剂盒通过聚合酶链反应（PCR）确认[具体微生物名称1]和[具体微生物名称2]的存在。
调查显示，从事家禽养殖的大多是中年男性。大多数农民只有小学文化程度，在未接受培训的情况下从事养殖约5年。在研究区域，37%的农民每天早上收集粪便并将其用作有机肥料。约58%的农民不知道粪便的卫生处理方法，且面临健康问题。在PCR检测中，在蔬菜、粪便、土壤和池塘水中均确认存在[具体微生物名称1]或[具体微生物名称2]或两者都有。
适当的家禽粪便管理做法可减少人类食物链中微生物制剂的可能污染。
