Bacterial food-borne illness outbreaks in northern Taiwan, 1995–2001

Introduction:This research aimed to identify and quantify potentially pathogenic Vibrio from different cultivations of bivalve shellfi sh in the State of Santa Catarina, Brazil, and water regions in the South Bay, as well as correlate the incidence of these microorganisms with the physicochemical parameters of marine waters. Methods: Between October 2008 and March 2009, 60 oyster and seawater samples were collected from six regions of bivalve mollusk cultivation, and these samples were submitted for Vibrio counts. Results: Twenty-nine (48.3%) oyster samples were revealed to be contaminated with one or more Vibrio species. The Vibrio parahaemolyticus and Vibrio vulnifi cus counts in the samples ranged from < 0.5 log 10 Most Probable Number (MPN) g -1 to 2.3 log 10 MPN g -1 oyster and from < 0.5 log 10 MPN g -1 to 2.1 log 10 MPN g -1 oyster, respectively. Of the 60 seawater samples analyzed, 44 (73.3%) showed signs of contamination with one or more vibrio species. The counts of V. parahaemolyticus and V. vulnifi cus in the samples ranged from < 0.3 log 10 MPN·100mL -1 to 1.7 log 10 MPN·100mL -1 seawater and from < 0.3 log 10 MPN·100mL -1 to 2.0 log 10 MPN·100mL -1 seawater, respectively. A positive correlation between V. vulnifi cus counts and the seawater temperature as well as a negative correlation between the V. parahaemolyticus counts and salinity were observed. Conclusions:The results suggest the need to implement strategies to prevent vibrio diseases from being transmitted by the consumption of contaminated bivalve shellfi sh.

“…At least 12 species of the Vibrio genus are potentially pathogenic to humans [1]. Particularly Vibrio parahaemolyticus and Vibrio vulnificus, but also Vibrio alginolyticus and Vibrio cholerae are known as causative agents of seawater-related illnesses, such as seafood poisoning in association with gastrointestinal infections [2][3][4] and infections of wounds and mucous membranes [5][6][7][8][9][10][11].…”

The number of reported Vibrio-related wound infections associated with recreational bathing in Northern Europe has increased within the last decades. In order to study the health risk from potentially pathogenic Vibrio spp. in the central Wadden Sea, the seasonal and spatial distribution of Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio alginolyticus and Vibrio cholerae were investigated at ten recreational beaches in this area over a 2-year period. V. alginolyticus and V. parahaemolyticus were found to be omnipresent all year round in the study area, while V. vulnificus occurrence was restricted to summer months in the estuaries of the rivers Ems and Weser. Multiple linear regression models revealed that water temperature is the most important determinant of Vibrio spp. occurrence in the area. Differentiated regression models showed a species-specific response to water temperature and revealed a particularly strong effect of even minor temperature increases on the probability of detecting V. vulnificus in summer. In sediments, Vibrio spp. concentrations were up to three orders of magnitude higher than in water. Also, V. alginolyticus and V. parahaemolyticus were found to be less susceptible towards winter temperatures in the benthic environment than in the water, indicating an important role of sediments for Vibrio ecology. While only a very small percentage of tested V. parahaemolyticus proved to be potentially pathogenic, the presence of V. vulnificus during the summer months should be regarded with care.

“…Most importantly, however, food contamination from these bacteria causes foodborne illness in consumers. The foodborne disease outbreaks due to these bacteria in Taiwan and other countries have been well reported [4,9]. Therefore, the development and application of a proper agent with antibacterial activity would be helpful in ensuring food safety.…”
