Detection of foodborne pathogens using DNA probes and a dipstick format

The detection of foodborne microorganisms has traditionally been done using microbiologically based methods. Such “gold standard” methods are generally reliable but have the disadvantages of being labor intensive, subjective, and time consuming. Over the last several years, the development of DNA probe-based methods has simplified the methods used to detect organisms such asSalmonella, Listeria, andE. coli by targeting the unique DNA or RNA sequences of these organisms using DNA probes and nonradioactive detection.
