目的了解目前动车快餐盒饭加工车间静态下空气洁净环境现状,为进一步完善其卫生管理措施提供科学数据。方法按照《铁路动车快餐盒饭食品安全控制要求》规定,采用CENTER310温湿度计、AREOTRAK9310计数器等仪器设备,测定动车快餐盒饭加工车间静态下空气洁净环境现状。结果检测数据表明,盒饭包装洁净区:ISO8.2;静态;关注粒径:5μm(48 961个/m~3);M(2 143;≥10μm);光学粒子计数器;沉降菌1个/皿;未检出致病菌。蔬菜加工洁净区:ISO8.3;静态;关注粒径:5μm(59 523个/m~3);M(5 148;≥10μm);光学粒子计数器;沉降菌2个/皿;未检出致病菌。热炒烹调洁净区:ISO8.2;静态;关注粒径:5μm(49 305个/m~3);M(2 418;≥10μm);光学粒子计数器;沉降菌1个/皿;未检出致病菌。米面制品洁净区:ISO8.2;静态;关注粒径:5μm(42 269个/m~3);M(2 059;≥10μm);光学粒子计数器;沉降菌0个/皿;未检出致病菌。结论《铁路动车快餐盒饭食品安全控制要求》中温、湿度及≥10μm粒子浓度指标设置不尽合理,需要及时修订。
Objective To understand the status quo of the static air clean environment under the static condition of the fast food box processing workshop and to provide scientific data for further improving its health management measures. Methods According to the requirements of “Food safety control of railway car fast lunch box food”, the equipment of CENTER310 hygrometer and AREOTRAK9310 counter was used to determine the static air clean status under the static condition. Results The detection data showed that the packing area of the packed lunch box was ISO8.2; static; the particle size of interest was 5μm (48 961 / m ~ 3); M (2 143; ≥10μm); optical particle counter; ; Not detected pathogenic bacteria. Vegetable processing and cleaning area: ISO8.3; static; attention to particle size: 5μm (59 523 / m ~ 3); M (5 148; ≥ 10μm); optical particle counter; sedimentation bacteria 2 / Germs. Thermal cooking area: ISO8.2; static; attention to particle size: 5μm (49305 / m ~ 3); M (2 418; ≥10μm); optical particle counter; sedimentation bacteria 1 / Pathogenic bacteria. Melamine products clean area: ISO8.2; static; attention to particle size: 5μm (42 269 / m ~ 3); M (2 059; ≥ 10μm); optical particle counter; sedimentation bacteria 0 / Germs. Conclusion The requirements of temperature control, humidity and particle index ≥10μm are not reasonable and need to be revised in time.
