Evaluation of contaminative status and safety of prevalent pathogenic organisms in edible raw aquatic products

  Objective   To know the contaminative status of prevalent pathogenic organisms in edible raw aquatics and their breeding environmentin pearl river delta region of Guang dong.

  Methods   325 samples were collected during two and half years and detected pathogenic organisms by the national hygienic standards and typical methods.Measures for controlling food safety were studied by sanitation standard operating procedure, disinfection measure, ultra-pressure ster ilization, radiation sterilization, etc.

  Results   79 prevalent pathogenic microorganisms were detected, including 7 biologial species.The accumulative positive rate was 24.31% in all samples and 50% in Luoshi shrimp; There were clonorchis endemicusin 5 samples among 25 raw fishes.The incidence of pathogenic microor ganisms was 14.46% for firs-tclass restaurants and 34.59% for other restaurants.Ultra-pressure and radiation technique could help to sterilize those pathogenic or ganisms in edible raw aquatics.

  Conclusion   Edible raw aquatics were contaminated by prevalent pathogenic organisms in pearl river delta region of Guangdong.It was necessary to strengthen the management of food hygienic and promulgate safe practices foredible raw aquatics.
