Rapid detection of Listeria monocytogenes, Salmonella, Campylobacter spp., and Escherichia coli in food using biosensors

Listeria, Campylobacter, Salmonella and Escherichia coli are among the most common causes of foodborne disease in humans, causing death and hospitalization with high costs. Their presence in different foods and environments, and their ability to adapt to varying conditions make early and rapid detection essential to ensure food safety. As food regulations and consumer expectations continue to advance around the world, biosensors that require little or no sample preparation to provide fast and sensitive foodborne bacterial detection attracted much attention. This review presents recently reported biosensors for Listeria, Campylobacter, Salmonella and E. coli detection which application in foods was superior to conventional microbiological methods in terms of rapidity, selectivity, sensitivity and affordability.

Automated summary

Listeria, Campylobacter, Salmonella, and Escherichia coli are common causes of foodborne disease in humans, making early and rapid detection crucial for food safety. Recently reported biosensors have shown superior performance in terms of speed, selectivity, sensitivity, and affordability compared to conventional microbiological methods for detecting these bacteria in food.
