Abstract
Diseases caused by food-borne pathogens constitute a major burden to consumers, food business operators, and national governments. Bacterial and viral pathogens are the major biotic factors influencing food safety. A vast array of culture dependent analytical methods and protocols have been developed. Recently, nucleic acid-based methods have begun to replace or complement culture-based methods for routine use in food control laboratories. Basic advantages provided by nucleic acid-based technologies are faster speed and more information, such as sub-species identification, antibiotic resistance, and food microbiology. In particular, PCR and alternative methods have been developed to a stage that provides good speed, sensitivity, specificity, and reproducibility with minimized risk of carryover contamination. This review briefly summarizes currently available and developing molecular technologies that may be candidates for involvement in microbiological molecular diagnostic methods in the next decade.
