Recent trends in the utilization of LAMP for the diagnosis of viruses, bacteria, and allergens in food

Foodborne diseases are becoming major scientific struggles for both developing and developed countries. Most foodborne infections are caused by microbial pathogens such as bacteria, viruses, and other food allergens. Hence early and accurate diagnosis of these foodborne pathogens is always preferable. To satisfy these concerns, plenty of isothermal amplification methodologies such as rolling circle amplification (RCA), helicase-dependent amplification (HDA), and recombinase polymerase amplification (RPA) have been developed. Among these, loop-mediated isothermal amplification (LAMP) is a widely usable, potential, and recognizable amplification technique achieved at a constant temperature around 60°C within 30–60 min by using only one kind of enzyme. As a robust gene amplification technique, it can be employed for the detection of bacteria, viruses, and other related food allergens. This technique has its own merits such as cost-effectiveness, facile manufacturing procedure, and consistency. In this chapter, we emphasize recent trends in designing the techniques, challenges, and the future prospects of LAMP in the detection of foodborne pathogens. These effective pathogen detection methods may offer potential benefits compared with existing conventional methods.
