Two hundred and sixty nine beef, 230 sheep and 165 pig carcase surface were examined bacteriologically. Direct and indirect contact examination techniques were utilised. Colony counts per cm2 were expressed in geometric progression. Counting procedures, direct and indirect contact examinations, and effects of chilling were considered. Subsequently, results from an additional 489 beef, 520 sheep, and 408 pig carcases were employed to illustrate a count classification arrangement against which bacteriological monitoring assessments could be measured.
对269头牛、230只羊和165头猪的胴体表面进行了细菌学检查。采用了直接和间接接触检查技术。每平方厘米的菌落数用几何级数表示。考虑了计数程序、直接和间接接触检查以及冷藏的影响。随后,采用另外489头牛、520只羊和408头猪胴体的结果来说明一种计数分类安排,可据此对细菌学监测评估进行衡量。
