The US Food and Drug Administration and the US Department of Agriculture (USDA) have announced a new action plan aimed at helping consumers reduce their risk of listeria monocytogenes, a bacteria that can lurk in uncooked food and on unclean surfaces and cause listeriosis.  Advice given to consumers to lower their risk of contracting the potentially deadly food borne illness includes avoiding unpasteurized foods, cooking food to temperatures high enough to kill the bacteria and cleaning kitchen counters and cutting boards thoroughly.
