大肠菌群广泛存在于人畜粪便中,作为卫生检验的指示菌,已应用多年。但迄今为止,仍沿用繁琐的三步法(即初发酵、平板分离和复发酵),给部队贯彻食品卫生法、普及食品卫生检验带来经费、设备和技术上的许多困难,也影响及时对食品实施卫生监督。为使基层单位能开展食品卫生检验工作,我们就目前有关文献的快速方法中选择红四氮唑快速显色法,并在其冷饮检查基础上对餐食具及冷荤小菜进行了实验研究,同时对培养基的配制和使用上加以观察改进,现报告如下。材料和方法 Coliform bacteria are widely found in human and livestock excrement, and have been used for many years as indicator bacteria for hygiene inspection. So far, however, complicated tedious three-step methods (ie, initial fermentation, plate separation and re-fermentation) are still in use, which have caused difficulties for troops in implementing the Food Sanitation Law and popularizing food hygiene inspection, as well as many difficulties in equipment and technology. Food hygiene supervision. In order to enable the grass-roots units to carry out food hygiene inspection, we select the rapid method for rapid reference colorimetric analysis of the literature, and in its cold drinks on the basis of inspection of food dishes and cold meat dishes were studied, at the same time On the preparation and use of medium to be observed and improved, are as follows.
