摘要
对新疆某个具有代表性的传统屠宰场刚宰杀完毕的23头牛胴体和宰杀后1~2 h间的17头牛胴体及羊屠宰车间入口处、中间过道处、出口处三个区间的36头羊胴体表面进行采样。按照GB/T4789.2—2003和GB/T4789.3—2003分别进行了菌落总数和大肠菌群两项微生物指标的测定。同时,还调查了各个车间不同位置空气的污染状况。以NY 5044—2008《无公害食品牛肉》和NY 5147—2008《无公害食品羊肉》作为参考。结果表明,传统牛羊屠宰场屠宰的牛羊胴体表面微生物污染程度较高,屠宰车间空气质量状况较差,影响了牛羊肉肉品的卫生质量。
To get the message of the hygienic quality in the process of traditional cattle and sheep slaugh- ter in Xinjiang, the present study was conducted to investigate 23 cattle carcasses just after slaughter, 17 cattle carcasses between 1 to 2 h after slaughter and 36 sheep carcasses at different position in the house-- the entrance passageway, the middle passageway and the exit of workshop. According to GB/T4789.2-- 2003 and GB/T4789.3 2003 the total numbers of colony and the coli group were determined. The present study was also carried out to investigate the microbial contamination of the air at different position in dif- ferent houses at the same time. NY 5044--2008((Non-public disruption food beef)) and NY 5147--2008 ((Non-public disruption food mutton)) were used as reference. The results showed that the status of micro- bial contamination in the process of traditional cattle and sheep slaughter was more serious,the air condi- tion was worse, and all of these influenced the quality of beef and mutton.
