摘要

尽管波哥大河受到生活和工业废水的严重污染,但它仍然是各种用途的重要水源,包括 La Ramada 灌区的农业用水。本研究旨在估算食用用波哥大河水灌溉的莴苣引起沙门氏菌相关疾病的风险。我们从 4 个不同地点采集了生菜样本,所有样本均使用拉玛达河水灌溉。研究方法包括从莴苣叶片上分离沙门氏菌,通过 SS 琼脂上的平板计数进行定量,以及通过在添加了氨苄西林或环丙沙星的培养基上生长来确定抗生素耐药菌的浓度。结果显示,1、2 和 3 号地点的沙门氏菌浓度分别为 103.59、102.66 和 104.56 CFU/克生菜,1、2 和 3 号地点的耐氨苄西林沙门氏菌浓度分别为 101.93、101.31 和 102.07 CFU/克生菜。从 4 号地点采集的生菜样本中没有发现菌落。值得注意的是,我们在所有地点都没有检测到对环丙沙星有抗药性的分离菌株。不同采样点的沙门氏菌浓度差异很大。沙门氏菌属的浓度可用于预测每日发病概率,沙门氏菌属的发病概率为 0.59(0.33 至 0.78,CI 95%),耐氨苄西林沙门氏菌属的发病概率为 0.3(0.03 至 0.53,CI 95%)。

Risk of Illness with Salmonella Spp. and Antibiotic-Resistant Salmonella sp. due to Consumption of Lettuce Irrigated with Water from La Ramada Irrigation District.

Despite heavy contamination of the Bogotá River with domestic and industrial waste, it remains vital for various purposes, including agricultural use at La Ramada Irrigation District. There are important concerns regarding pathogen concentrations in irrigation water at La Ramada, including the presence of antibiotic-resistant Salmonella spp. This study aimed to estimate the risk of Salmonella-related illness from consuming lettuce irrigated with Bogotá River water at La Ramada. We collected lettuce samples from 4 different sites, all irrigated with water from La Ramada. The methodology involved a process to detach Salmonella spp. from lettuce leaves, quantification through plate counts on SS agar, and establishment of antibiotic-resistant bacteria concentrations through growth on media supplemented with ampicillin or ciprofloxacin. The results showed concentrations of Salmonella spp. of 103.59,102.66, and 104.56 CFU/g lettuce at sites 1, 2, and 3, respectively, and ampicillin-resistant Salmonella spp. of 101.93, 101.31, and 102.07 CFU/g lettuce at sites 1, 2, and 3, respectively. No colonies were obtained from lettuce samples collected from site 4. Notably, we detected no isolates resistant to ciprofloxacin at any of the sites. Salmonella spp. concentrations varied greatly among sampling sites. Salmonella spp. concentrations were used to predict the daily probability of illness, with a probability of 0.59 (0.33 to 0.78, CI 95%) for Salmonella spp. and 0.3 (0.03 to 0.53, CI 95%) for ampicillin-resistant Salmonella spp.

期刊介绍: Foodborne Pathogens and Disease is one of the most inclusive scientific publications on the many disciplines that contribute to food safety. Spanning an array of issues from "farm-to-fork," the Journal bridges the gap between science and policy to reduce the burden of foodborne illness worldwide. Foodborne Pathogens and Disease coverage includes: Agroterrorism Safety of organically grown and genetically modified foods Emerging pathogens Emergence of drug resistance Methods and technology for rapid and accurate detection Strategies to destroy or control foodborne pathogens Novel strategies for the prevention and control of plant and animal diseases that impact food safety Biosecurity issues and the implications of new regulatory guidelines Impact of changing lifestyles and consumer demands on food safety.
