采集样品的包装和运输要求

在样品采集、运输、储存等过程中,应采取必要的措施防止交叉污染和环境污染及食品中微生物的数量和生长能力发生变化。

样品应在接近原有储存温度的条件下传送,冷冻、冷藏的样品应能达到规定温度,样品送到实验室应越快越好,如果路途遥远,应将不需冷冻的样品都保存在2℃-5℃环境中;

冷冻产品可以冷冻运输或者在允许解冻的情况下冷藏运输,但样品温度不得超过 8℃,一旦解冻不得再次冷冻,保持冷却即可。


2.采集样品的包装和运输要求

   定型包装的产品应采集待销的、包装完好的、在保质期内的而且要有完整的标识信息(包括生产厂家、批号、保质期、储存温度等)

每个样品的包装上贴标签以便识别样品,标签内容包括样品名称、样品批号/生产日期、采样地点、采样时间、采样人等。


3.采样过程中对人员的要求

   采样人员应经过采样、微生物技术培训,具有独立工作能力;

   采样人员至少2名,认真填写采样单,2人签字确认;
