  Food Partner Network News The hygiene of tableware is under the Food Safety Law Basic requirements are also an important part of the management of the catering industry. The microbiological index of tableware is an important indicator for evaluating the sanitary condition of tableware. It is closely related to the occurrence of food-borne diseases. It is also an important part of the routine health supervision and special random inspection carried out by the health supervision department. The National Food Safety Standard for Disinfecting Meal (Drinking) Utensils (GB14934-2016) stipulates two microbial limits for coliforms and Salmonella for catering service providers, group meal delivery units, and centralized cleaning and disinfection service units for tableware, which are often used for evaluation. Important indicators of sanitary conditions such as food and tableware are often used as an important indicator of the actual implementation effect of good hygiene practices. The Beijing Food and Drug Safety Enterprise Alliance compiled data on the microbiological test results of documents on CNKI in the past five years when the standard was released with the subject word”disinfection of tableware”, and a total of 33 documents were selected and included. The authors of the documents were mainly related health departments in various regions. .

  一. Provincial administrative area

   From the perspective of provincial administrative regions, 19 of my country’s 34 provincial administrative regions are involved, and the total number of tableware samples involved is 38267 pieces/batch, including Shanghai , Yunnan, Beijing, Jilin, Sichuan, Tianjin, Shandong, Shanxi, Guangdong, Jiangsu, Jiangxi, Hebei, Zhejiang, Gansu, Fujian, Liaoning, Shaanxi, Anhui, Guangxi, basically covering several large areas in my country’s southeast, northwest. The publishers of the data are mainly local health departments. Therefore, the data results are representative and authoritative.

  Second, detection of coliform bacteria

   From the results of coliform testing, 38,267 pieces/batch of tableware samples were involved. All samples were tested for coliforms, including 29,957 qualified samples. /Batch, 8310 unqualified pieces/batch. In terms of provincial administrative regions, the pass rate of coliforms is 82.95%, the highest pass rate is 94.44%, the lowest pass rate is 57.24%; the unqualified rate is 17.05%, the highest unqualified rate is 42.76%, and the smallest is 5.56%. Among the 19 provincial administrative regions, 6 have a pass rate higher than 90%, 7 have a pass rate of 80-90%, 3 have a pass rate of 70-80%, and a pass rate of less than 70%There are 3 of them. Taking into account the convenience and economy of coliform detection and the high indication of the sanitary condition of tableware, in general, the sanitary condition of tableware disinfection in my country’s catering industry is relatively good, but there is still room for further improvement. Further strengthen the process specification and management of tableware disinfection, and supervise the implementation of various disinfection systems and measures.

   3. Salmonella detection

   From the results of Salmonella detection, 11522 samples/batch of 38,267 tableware samples were tested for Salmonella, with a detection rate of 30.11%. The Salmonella qualification rate of samples that have been tested for Salmonella is 100%. Among the 19 provincial administrative regions, 5 salmonella were detected with a 100%detection rate, 8 were partially tested, and 5 were not tested. According to the test results, 11522 samples/batch of Salmonella tests carried out in the literature did not detect Salmonella. In addition, considering that the detection method of Salmonella is relatively complicated with larger intestinal flora, the proportion of samples actually tested during the daily supervision and sampling of tableware is relatively low. Therefore, first, it is recommended that the market supervision department further explore the application scenarios of further refinement of Salmonella detection in the process of daily sanitation supervision and random inspection, and improve the cost-effectiveness of detection to help improve the sanitation level of catering; Second, it is necessary to carry out the prevention and control of Salmonella in tableware The simple and economical detection technology and equipment research and development of indicators increase the detection rate.
