食具能作为许多传染病、特别是肠道传染病的传播因子,是早已肯定的事实,就部队中食具的带菌检查结果来看,也说明了这一问题。例如,对某部队50份碗、筷的细菌学检查结果,大肠菌阳性者27份;另一部队23份食具,检出大肠菌者14份,即污染者均占食具的半数以上。再举一个对某校一个食堂的炊具的细菌学检查结果的例子,检查对象包括案板、菜墩、菜刀架、勺把、抹布、水龙头等,共检查33份,大肠菌阳性者21份,平均每份含细菌数为108367个,该食堂6份碗、筷中,检出大肠菌者4份,每份平均带有细菌18783个。从以上资料中不难看出,公共食堂中食具与炊具的细菌污染情况是普遍而严重的。大家知道,大肠菌的存在是粪便污染的指标,如
The availability of utensils as a transmission factor for many infectious diseases, particularly gut infections, has long been a fact confirmed, as is the case with regard to the carriage test of utensils in units. For example, a unit of 50 bowls, chopsticks bacteriology test results, 27 were positive for coliform; another unit of 23 utensils, 14 were detected coliform bacteria, that polluters accounted for more than half of the utensils. Another example of the bacteriology test results of a cooker in a canteen of a school, including checkerboard, picker, chopper holder, spoon handle, rag, faucet and the like, were examined in 33 samples and 21 samples of coliform positive samples. The average Each containing 108367 bacteria, the canteen 6 bowls, chopsticks, coliform were detected in 4, each with an average of 18783 bacteria. From the above information is not difficult to see that the public canteens and cooking utensils in the case of bacterial contamination is widespread and serious. We all know that the presence of coliform is an indicator of faecal contamination, such as
