Abstract：
The meat industry has received great attention in Mongolia, having over 70 million livestock, and is important to the nation\'s economy. Systematic microbiological testing of carcasses has not been mandatorily regulated in all abattoir premises, and the efficacy of the introduction of the Good Hygiene Practice and Hazard Analysis Critical Control Points (HACCP) to some plants has not yet been tested microbiologically in Mongolia. Therefore, samples were collected from two establishments: plant A with an HACCP certificate from a third party and plant B without an HACCP certificate. The rates and levels of the total bacterial count (TBC) as overall hygiene indicators, the Enterobacteriaceae count (EBC) as fecal contamination indicators, and the Staphylococcus spp. count (SC) as personal hygiene indicators were determined on different parts of beef carcasses. The contamination rates in most parts were lower in plant A than in plant B (e.g., TBC in the rump and flank: 103-105 and 105-107, in plant A vs. 104-106 and 105-108 in plant B, respectively). Plant A also had a lower EBC and SC (p < 0.001). Furthermore, 2 out of 100 beef carcasses (2%) were positive for enterohemorrhagic Escherichia coli as a foodborne pathogen indicator in plant A.
摘要：
肉类工业在蒙古受到了极大的关注,拥有超过七千万头牲畜，对国家经济很重要。没有在所有屠宰场强制监管尸体的系统微生物测试，在蒙古，尚未对某些植物引入良好卫生实践和危害分析关键控制点（HACCP）的功效进行微生物测试。因此,样品从两个机构收集:具有来自第三方的HACCP证书的植物A和没有HACCP证书的植物B。总细菌计数（TBC）的比率和水平作为总体卫生指标，肠杆菌科细菌计数（EBC）作为粪便污染指标，和葡萄球菌属。在牛肉尸体的不同部位确定了作为个人卫生指标的计数（SC）。A厂大部分地区的污染率低于B厂(例如，臀部和侧翼的TBC：103-105和105-107，在植物A与工厂B中的104-106和105-108，分别)。植物A也具有较低的EBC和SC(p<0.001)。此外，100个牛肉屠中有2个（2％）对肠出血性大肠杆菌呈阳性，作为植物A中的食源性病原体指标。
