Worldwide, foodborne illness is often associated with consumption of meats and poultry products sold at retail markets. A cross-sectional retail food study was conducted in Bangkok, Thailand to assess the prevalence of bacterial pathogens on retail food samples. Raw chicken, beef, pork, and chicken eggs were purchased from fresh markets and supermarkets and tested for Salmonella spp., Campylobacter spp., Arcobacter spp., and Enterococcus spp. Suspect bacterial pathogens were isolated by differential culture and Salmonella species were serotyped. A total of 200 samples were collected from 50 markets between May and August 2003. Of the 200 samples tested, 121 (61%) were positive for at least one Salmonella spp. serogroup. A total of 175 Salmonella spp. were isolated. The most common serotype was Salmonella Anatum, followed by S. Corvallis and S. Derby. Campylobacter spp. were found in 31 (15.5%) of 200 samples. C. jejuni was isolated from 15% of fresh market chicken samples and 35% of supermarket chicken samples. Arcobacter spp. were isolated from 42 (21%) samples; fresh market chicken had significantly higher A. butzleri contamination than supermarket chicken. The presence of Enterococcus spp., an indication of fecal contamination, was detected in 188 (94%) samples, including 100% of the beef and pork sources. Few studies have examined retail food contamination in Thailand. In particular, the high prevalence of samples with Arcobacter spp. warrants further study to determine pathogenicity.
在全球范围内，食源性疾病通常与零售市场销售的肉类和家禽产品的消费有关。在泰国曼谷进行了一项横断面零售食品研究，以评估零售食品样本中细菌病原体的流行情况。从新鲜市场和超市购买生鸡肉、牛肉、猪肉和鸡蛋，检测沙门氏菌属、弯曲杆菌属、弓形杆菌属和肠球菌属。通过鉴别培养分离出可疑细菌病原体，并对沙门氏菌进行血清分型。2003年5月至8月期间，从50个市场共采集了200个样本。在检测的200个样本中，121个（61%）至少对一种沙门氏菌血清群呈阳性。共分离出175株沙门氏菌。最常见的血清型是阿纳托姆沙门氏菌，其次是科瓦利斯沙门氏菌和德比沙门氏菌。在200个样本中的31个（15.5%）中发现了弯曲杆菌属。空肠弯曲杆菌从15%的新鲜市场鸡肉样本和35%的超市鸡肉样本中分离出来。从42个（21%）样本中分离出弓形杆菌属；新鲜市场鸡肉的布氏弓形杆菌污染明显高于超市鸡肉。在188个（94%）样本中检测到肠球菌属的存在，这表明存在粪便污染，其中包括100%的牛肉和猪肉来源。很少有研究调查泰国零售食品的污染情况。特别是，弓形杆菌属样本的高流行率值得进一步研究以确定其致病性。
