冻藏时间对海产品中霍乱弧菌检出率的影响

Eeffect of refrigeration time on positive rate of vibrio cholerae in marine products

目的:探寻不同的冻藏时间对海产品中霍乱弧菌的检出率的影响。方法:对已被染菌的冻秋刀鱼在不同的冻藏时间内,进行检测霍乱弧菌的实验。结果:已染菌的秋刀鱼样本,在冻藏期为25d以内时,其霍乱弧菌的检出率能达到100%;而当冻藏时间延长至60d时,其霍乱弧菌的检出率为91.43%;当冻藏时间达到90d时,霍乱弧菌的检出率为83.33%;当冻藏时间增加至120d时,其霍乱弧菌的检出率仅为53.33%。结论:水产品的冻藏期在25d内,对霍乱弧菌的检出率无影响,而当冻藏期超过25d时,霍乱弧菌的检出率则随时间的增加而降低。

Objective： Try to find out the effect of different refrigeration time on positive rate of vibrio cholerae in marine products. Methods： In different refrigeration time, the samples which were taken vibro cholerae will be tested. Results： When the refrigeration time less than 25 days, the positive rate was 100%; When the refrigeration time was added to 60 days, the positive rate was 91.43%; When the refrigeration time arrived at 60 days, the positive rate was 83.33%; The same as, when the refrigeration time increased to 120 days, the positive rate was 53.33%. Conclusions： the positive rate was unacted on refrigeration time within 25 days. And that, when the refrigeration was more than 25 days, the positive rate decreased with increasing the refrigeration time.
