SN标准法和3M Petrifilm法检测水产品中 细菌总数的比较

目的 比较用3M Petrifilm法与用SN标准法对水产品中细菌总数的检测结果。方法 采用3M Petrifilm法和SN标准法同时对水产品（鱿鱼、螺肉、虾、蟹肉等）中细菌总数进行检测比对。结果 两种方法的检测结果比较，差异无统计学意义（P﹥0.05），且3M Petrifilm法具有操作简便、灵敏度高的优点。结论 3M Petrifilm法可作为水产品中细菌总数检测的新方法 。结论 3M Petrifilm法可用于水产品中细菌总数的检测。

Comparison SN standard method and 3M Petrifilm method for determination of bacterial count in aquatic products

Objective To compare the determination of bacterial count for aquatic products by 3M Petrifilm method and SN standard method. Methods Samples were taken and detected by 3M Petrifilm method and SN standard method. Results There was no significant difference(P>0.05)in using these two methods to determine bacterial count in aquatic products. 3M Petrifilm method has higher sensitivity and simpler opera-tion than SN standard method. Conclusion 3M Petrifilm method can be used to detect bacterial count in aquatic products as SN standard method.
