Abstract:

Objective   To find out the sanitary condition and disinfection effects in Jinan Railroad Jurisdiction Area from 2006 to 2010, and to reduce the occurrence and prevalence of infectious diseases. Methods   In compliance with GB 14934-94 hygienic standard for disinfection of dinner and drinking set, disinfected tableware was randomly chosen for an analysis of the sensory index, physicochemical index, colon bacilli and pathogenic bacteria. The obtained data was analyzed by Chi-square test with SPSS 13.0. Results   Over the period from 2006 to 2010, a total of 10,623(96.55%) sets of tableware reached the standard. The pass rate tended to annually rise, with the 1st and 4th quarters higher than the rest (χ2=38.60, P<0.01). It was higher in kindergartens and dining cars than hotels, restaurants and canteens (χ2=163.78, P<0.01). Cups, disposable dining set and other tableware of smaller size had a higher pass rate than plates, bowls and vegetable dishes (χ2=42.70, P<0.01). Conclusion   During the period 2006-2010, Jinan Railway Jurisdiction Area has a relatively high rate in dinner service hygiene. In order to further raise the pass rate, health organizations, centers for disease control(CDC) and departments concerned should maintain the achieved effects and lay more emphasis on hygiene supervision, technical guidance and administration of tableware, especially those of large size frequently used in the 2nd and 3rd quarters.
