【摘要】：目的 了解荊門市學(xué)生餐生產(chǎn)加工過程中微生物污染情況,為指導(dǎo)食品加工單位改善衛(wèi)生條件提供參考。方法 2015年4—9月方便抽取4所市級中學(xué),對學(xué)生餐加工過程各環(huán)節(jié)的236份樣本進(jìn)行微生物指標(biāo)檢測。結(jié)果 學(xué)生餐制作環(huán)節(jié)中30%的樣本大腸菌群計(jì)數(shù)10 cfu/m L,大腸菌群計(jì)數(shù)最大值為7.0×105cfu/m L。金黃色葡萄球菌的檢出率為2%(4/228),陽性樣本為2份環(huán)境(豆制品操作臺(tái)面、盛放炒菜的方盆)和2份原輔料(鯽魚、雞肉)樣本。生活用水、物表環(huán)境樣本和成品學(xué)生餐微生物指標(biāo)不合格率分別為75%(6/8),79%(50/63)和53%(21/40),差異有統(tǒng)計(jì)學(xué)意義(χ2=8.439,P=0.014)。結(jié)論 荊門市學(xué)生餐生產(chǎn)加工過程各環(huán)節(jié)樣本大腸菌群污染普遍,環(huán)境和原輔料樣本致病菌風(fēng)險(xiǎn)隱患突出。建議加強(qiáng)對學(xué)生餐生產(chǎn)加工各環(huán)節(jié)衛(wèi)生的監(jiān)管力度。
[Abstract]:Objective to investigate the microbial contamination in the course of student meal production and processing in Jingmen City, and to provide reference for improving hygienic conditions in food processing units. Methods from April to September 2015, 236 samples of students' meal processing were collected from 4 municipal middle schools and tested for microbiological indexes. Results the coliform count of 30% sample was 10 cfu/m / L and the maximum of coliform count was 7.0 脳 105cfu/m L. The detection rate of Staphylococcus aureus was 2X / 228g, and the positive samples were 2 samples of environment (bean products operating table, roasted dish) and 2 samples of raw and auxiliary materials (crucian carp, chicken). The unqualified rates of microbial indexes in domestic water, surface environment samples and finished student meals were 75 / 6 / 8 / 79 / 50 / 63 and 53 / 21 / 40 respectively. The difference was statistically significant (蠂 ~ 2 = 8.439) and P ~ (0. 014) ~ 0. 014% (蠂 ~ 2 = 8. 439%, P < 0. 014). Conclusion the contamination of coliform bacteria in the samples of Jingmen students' meal production and processing process is widespread, and the risks of pathogenic bacteria in the samples of environment and raw and auxiliary materials are obvious. It is suggested to strengthen the supervision of the hygiene in the production and processing of student meals.
