Infectious diseases associated with molluscan shellfish consumption.
A history of shellfish-vectored illnesses (i.e., those associated with consumption of clams, oysters, mussels, and scallops) occurring in the past nine decades is presented. Typhoid fever was a significant public health problem among consumers of raw molluscan shellfish earlier in this century. The development of more effective sewage treatment procedures and the institution of a national progr...
متن کاملA nested reverse transcriptase PCR assay for detection of small round-structured viruses in environmentally contaminated molluscan shellfish.
We describe the evaluation of a nested reverse transcriptase PCR (RT-PCR) procedure for the detection of small round-structured viruses (SRSVs) in molluscan shellfish and the application of this assay for the detection of SRSVs in commercially produced shellfish and in shellfish implicated in outbreaks of gastroenteritis. The range of virus strains detected and the sensitivity of detection were...
متن کاملDetection and quantification of noroviruses in shellfish.
Noroviruses (NoVs) are the most common viral agents of acute gastroenteritis in humans, and high concentrations of NoVs are discharged into the environment. As these viruses are very resistant to inactivation, the sanitary consequences are contamination of food, including molluscan shellfish. There are four major problems with NoV detection in shellfish samples: low levels of virus contaminatio...
متن کاملFood Safety Impacts from Post-Harvest Processing Procedures of Molluscan Shellfish
Post-harvest Processing (PHP) methods are viable food processing methods employed to reduce human pathogens in molluscan shellfish that would normally be consumed raw, such as raw oysters on the half-shell. Efficacy of human pathogen reduction associated with PHP varies with respect to time, temperature, salinity, pressure, and process exposure. Regulatory requirements and PHP molluscan shellfi...
متن کاملDistribution of human virus contamination in shellfish from different growing areas in Greece, Spain, Sweden, and the United Kingdom.
Viral pollution in shellfish has been analyzed simultaneously across a wide range of geographical regions, with emphasis on the concomitant variations in physicochemical characteristics and social features. The methods for sample treatment and for the detection of human enteric viruses were optimized by the participating laboratories. The second part of this study involves the selection of a pr...
