microbiological quality of randomly selected ready-to-eat foods sampled between 2003 and 2005 in wales, uk.since 1995, the publicly funded ready-to-eat food sampling and examination activities in wales have been coordinated and structured, using a novel approach for the identification of samples and premises. the latest set of data from this surveillance system reports the results from 3391 ready-to-eat foods sampled between november 2003 and march 2005. during this seventeen-month period all samples were examined for aerobic colony count, escherichia coli, listeria spp., bacillus cereus, salmonella, ...200616503065
microbiological quality of ready-to-eat foods: results from a long-term surveillance program (1995 through 2003).the coordination of food sampling activities across wales, a part of the united kingdom with a population of approximately 3 million, led to the establishment in 1995 of a coordinated food-sampling program designed to monitor on a long-term basis the microbiological quality and safety of specific ready-to-eat products. this surveillance system has been ongoing for 9 years and has generated a database of microbiological and associated demographic results for 15,228 ready-to-eat food samples. the ...200521132974

variation in the annual unsatisfactory rates of selected pathogens and indicators in ready-to-eat food sampled from the point of sale or service in wales, united kingdom.the welsh food microbiological forum "shopping basket" survey is a long running, structured surveillance program examining ready-to-eat food randomly sampled from the point of sale or service in wales, united kingdom. the annual unsatisfactory rates for selected indicators and pathogens for 1998 through 2008 were examined. all the annual unsatisfactory rates for the selected pathogens were <0.5%, and no pattern with the annual rate was observed. there was also no discernible trend observed for t ...201223212024
epidemiological typing of bacillus cereus by amplified fragment length polymorphism.a simple amplified fragment length polymorphism method was developed for the epidemiological typing of bacillus cereus. the method was applied to 21 cultures from seven food poisoning and eight non-food poisoning incidents. results were compared with those obtained by conventional serotyping using flagellar antigens and assessed in relation to epidemiological data. amplified fragment length polymorphism was found to be highly reproducible and 16 different profiles (each unique to the 15 incident ...200010792663
microbiological quality of ready-to-eat food served in schools in wales, united kingdom.a survey of the general microbiological quality of ready-to-eat food served in schools was undertaken across wales, united kingdom. of the 2,351 samples taken, four were identified as containing unsatisfactory counts of escherichia coli, four contained unsatisfactory counts of staphylococcus aureus, and one contained an unacceptable count of bacillus cereus when compared with guidelines for the microbiological quality of ready-to-eat food published by the united kingdom public health laboratory ...200919205487
risk factors for outbreaks of infectious intestinal disease linked to domestic catering.the epidemiology of general outbreaks of infectious intestinal disease associated with domestic catering for large numbers is described and compared with foodborne outbreaks in other settings. from 1 january 1992 to 31 december 1994, the phls communicable disease surveillance centre identified 101 foodborne general outbreaks of infectious intestinal disease associated with domestic catering in england and wales (16% of all foodborne outbreaks). salmonella species were associated with 77 of the 1 ...19968990573
