Investigation on status of pollution of vibrio cholera in seafood and aquatic products in 12 provinces of China in 2005

Abstract

To understand the pollution rates of vibrio cholera (V. cholera) in different seafood, aquatic products and their circulatory processes, so as to help making measures for cholera control and prevention. Different seafood, aquatic products and breed water specimen collected from 12 provinces of China were tested from July to September in 2005. A total of 12 104 samples of seafood and aquatic products were tested and the average pollution rate of vibrio cholera was 0.52%. The positive isolate rate of turtle sample (1.72%) was the highest among all samples. The second higher isolated rate was 1.14% in water specimen of turtle breed pool. The positive rate of bullfrog was 0.50%. The percentage of toxin strains was 47.54% and 79.31% of them were isolated from turtle and water samples of turtle breed pool. The important sector of the pollution of vibrio cholera was in turtle breed pool (2.38%). The average pollution rate of vibrio cholera in seafood and aquatic products in 12 provinces of China was low. It should be very necessary to supervise the sanitation in turtle breed for controlling and preventing the vibrio cholera.
