Evolving techniques for the detection of Listeria monocytogenes: underlining the electrochemical approach

Foodborne illness is posing major health problems among all world population. Among all pathogens, bacteria are causing more severe infections in food samples. Listeria monocytogenes is most lethal foodborne illness in human, causing approximately 1600 people infected and 260 deaths each year in the USA. In this review, numerous strategies of detection are presented together with discussions about their pros and cons. The primary emphasis has been done on electrochemical detection methods for L.monocytogenes. More than hundred research papers have been critically studied to elucidate the impact of L.monocytogenes on mortality and global socio-economic development. The literature study proves that electrochemical approach is the best among all traditional methods and using aptamers as biological recognition elements offer more advanced features to the diagnosis. Studies concluded that apta-sensors increase the sensitivity and specificity of L.monocytogenes detection.
