    摘要:

    目的 比较不同限量值对我国婴幼儿配方粉中蜡样芽胞杆菌污染带来的风险大小。方法 利用我国零售阶段婴幼儿配方粉中蜡样芽胞杆菌定量监测数据,基于婴幼儿配方粉中蜡样芽胞杆菌的微生物风险暴露评估模型,在澳大利亚新西兰和加拿大设定标准的基础上,假定其他8种限量值,共10种限量值,计算我国婴幼儿配方粉中蜡样芽胞杆菌污染带来的风险大小。结果 婴幼儿配方粉从冲调到喂养的时间分别为2、3和4 h时,婴幼儿配方粉中蜡样芽胞杆菌的限量值所起的作用不同。澳大利亚新西兰采用的限量值[n=5,c=0,m=100 CFU/g]如果应用于我国,在喂养总时间2、3 h时,风险为0;喂养总时间4 h时,相对于其他9种限量值的残留风险,该限量值的残留风险最低,降低了约36%,不合格率为11.28%(1 128/10 000)。在牺牲11.28%市场奶粉的基础上,较好的控制了风险。结论 本研究通过风险大小的比较,可筛选出可能应用于我国婴幼儿配方粉中蜡样芽胞杆菌管理的限量值。

    Abstract:

    Objective To compare the risk of Bacillus cereus contamination in powdered infant formula (PIF) in China under ten different limit levels. Methods The quantitative retail stage monitoring data of Bacillus cereus in PIF in China was used. Based on the microbial risk exposure assessment model of Bacillus cereus in PIF, and the criteria set by Australia, New Zealand and Canada, the other 8 limit levels were assumed. The risk of Bacillus cereus contamination in PIF in China was calculated under the ten limit levels. Results The risks were different under ten limit levels of Bacillus cereus in PIF when the period from preparation to feeding lasts for 2,3 and 4 hours. If the limits adopted in Australia and New Zealand [n=5, c=0, m=100 CFU/g] was applied to China, the total risk was 0 under 2 and 3 hours. Under 4 hours, compare with the other nine limit levels,the standard had the lowest residual risk, which was reduced by more than 36%, and the failure rate was 11.28% (1 128/10 000). Based on the sacrifice of 11.28% of the market milk powder, the risk was better controlled. Conclusion This study screened the limit levels that might be applied to the management of Bacillus cereus in PIF in China through the comparison of risks.
