摘　　要：目的:为确保食品中蜡样芽孢杆菌检测结果的精确度。方法:依据GB 4789.14-2014中平板计数法对食品中蜡样芽孢杆菌的检测结果进行不确定度的评定。结果:蜡样芽孢杆菌检测结果的扩展不确定度为0.28,当样品中蜡样芽孢杆菌平板计数法的检测结果以平行样对数值的平均值表示时,其取值区间为3.17±0.28。结论:建立的方法评定的不确定度可适用于食品的合格性判断。Objective. To ensure the accuracy of testi According to GB 4789. 14-2014, the uncertainty ng of results of Bacillus cereus in food. Methods： plate count method for detection of Bacillus cereus in food is evaluated. Results： The expanded uncertainty of detection results is 0.28, when the testing result of Bacillus cereus in food by using the plate count method is in parallel to the sample for average value, the value range is 3.17±0.28. Conclusion： The uncertainty evaluation can accurately evaluate the eligibility of food and ensure the safety of food.
