在莫罗戈罗市进行了一项调查，以评估屠宰牛的可能性，这对公共卫生构成了感染嗜热弯曲杆菌污染身体的风险。就屠宰牛的来源、动物和身体的运输方法、屠体处理、肉类储存设施、清洁水的获取和食品卫生做法等问题与屠宰者和肉店店主进行了面谈。从107头屠宰牛身上采集了粪便样本，并在屠宰后采集了去脏的四个不同部分(即火腿、颈部、骨盆和大腿肌肉)的粪便样本。此外，还在不同的肉店采集了107份用于弯曲杆菌培养的牛肉样品。样本按Skirrow方案进行标准细菌学检查。调查发现，肉店在不卫生的情况下进行屠宰、调味和处理肉类。屠宰牛中嗜热弯曲杆菌的感染率为5.6%，屠宰后屠体和商店牛肉的污染率分别为9.3%和1.9%。分离出的嗜热弯曲菌以空肠弯曲菌为主(88.9%)，大肠埃希菌为11.1%。这项研究的结果表明，人类有可能从牛肉中感染人畜共患弯曲杆菌，特别是在肉类准备和加工不正确的情况下。需要更多的工作来确定人畜共患肠道弯曲杆菌病在人类中的规模以及研究地区牛和其他动物的流行病学作用。
An investigation was conducted in Morogoro municipality to assess the likelihood of slaughter cattle posing public health risk of contaminating carcasses with thermophilic Campylobacter. Butchers and meat shopkeepers were interviewed on source of slaughter cattle, method of animal and carcass transportation, carcass dressing, meat storage facilities, access to clean water and availability of food hygiene practices. Faecal samples were collected from 107 slaughter cattle and after slaughter; four different parts of dressed carcasses (i.e. from ham, neck, pelvis and thigh muscles) were also sampled. In addition 107 cattle meat samples for Campylobacter culture were collected in different meat shops. The samples were subjected to standard bacteriological examination using Skirrows protocol. It was found that cattle slaughter, dressing and meat handling in meatshops was done under unhygienic condition. Thermophilic Campylobacter prevalence in slaughter cattle was 5.6% while contamination rate of dressed carcasses and cattle meat at shops was 9.3% and 1.9%, respectively. The majority of thermophilic Campylobacter isolated were C. jejuni (88.9%) while C. coli was isolated at 11.1%. Findings of this study suggest possibility of humans acquiring zoonotic Campylobacter infections from cattle meat particularly when meat preparation and processing is not done properly. More work is required to establish the magnitude of zoonotic enteric Campylobacteriosis in humans and epidemiological role of cattle and other animals in the study area.
