Research ArticleOpen accessIn the abstractA Mini Review: Cholera Outbreak via ShellfishR. Suzita, A. S. Abdulamir, Fatimah Abu Bakar, R. SonProblem statement: Food borne illness occurs all over the world. Vibrio cholerae is the etiological agent of cholera which is spread by contaminated food, water or direct fecal contact with food handlers. There are also examples of sporadic outbreaks of illness attributed to raw products eaten unprocessed. Consequently, there was a widespread concern that food in international trade carries pathogenic … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 8,318 accessesView PDFCite
