"New" food-borne pathogens of public health significance

Abstract

Recent work by epidemiologists and microbiologists has uncovered several hitherto unrecognized food-borne bacterial pathogens of public health significance. One of these, Listeria monocytogenes, has attracted considerable attention because of two major cheese-related outbreaks of listeriosis that were characterized by cases of meningitis, abortion, and perinatal septicemia. Thus far, L. monocytogenes has been responsible for well over 300 reported cases of food-borne listeriosis, including about 100 deaths, and has cost the dairy industry alone more than 66 million dollars as a result of product recalls. The ability of L. monocytogenes to grow at refrigeration temperatures, coupled with appearance of the pathogen in raw and processed meats, as well as poultry, vegetables, and seafood, makes this bacterium a serious threat to susceptible consumers and to the entire food industry. Yersinia enterocolitica, another psychrotrophic food-borne pathogen of recent concern, was linked to several outbreaks of yersiniosis associated with consumption of both raw and pasteurized milk, as well as contaminated water. Food-borne infections involving Y. enterocolitica typically result in enterocolitis, which may be mistaken for acute appendiciti...Continue Reading
