摘要

There is a definite and disturbing pattern here. Hie danger is a potentially lethal bacterium with an uncanny knack for surviving with a vengeance in processed foods, and recently in fruits. It defies routine refrigeration practices. To demonstrate its versatility, from 1999 to 2004, there were 4 outbreaks of Listeria infection from sandwiches purchased at hospitals in the United Kingdom.What makes this "bug" so hardy in conditions that seem to eradicate other bacteria? Agents proven to kill foodborne pathogens fare less successfully against Listeria. For instance, nitrite provides the color of cured meats and is an effective antimicrobial, killing diverse bacteria including Clostridium botulinum.
