Innovative Advances in Polymerase Chain Reaction (Pcr) Techniques for The Enhanced Detection and Identification of Foodborne Pathogens: A Comprehensive Review

Abstract

Background: Microbial pathogens pose significant threats to food safety and public health, with foodborne illnesses affecting millions worldwide. Traditional detection methods often lack the sensitivity and speed required for effective monitoring. Recent advances in Polymerase Chain Reaction (PCR)-based techniques have revolutionized pathogen detection, offering rapid and specific identification of foodborne microorganisms.

Methods: This review synthesizes recent developments in PCR methodologies, including multiplex PCR, Real-Time PCR, Reverse Transcriptase PCR (RT-PCR), and Next Generation Sequencing (NGS). A comprehensive evaluation of these techniques was conducted, focusing on their application in identifying bacterial, fungal, and viral pathogens across various food matrices. The review also discusses the challenges associated with traditional culture-based methods and highlights the benefits of modern molecular techniques.

Results: The findings indicate that PCR-based methods significantly enhance the detection and quantification of foodborne pathogens compared to conventional techniques. Real-Time PCR demonstrated high sensitivity and specificity for pathogens such as Salmonella, Listeria, and E. coli, while NGS provided insights into the microbial composition of food samples, enabling the identification of complex pathogen communities.

Conclusion: The integration of advanced PCR techniques into food safety protocols is essential for mitigating the risks associated with foodborne pathogens. These methodologies not only improve detection rates but also facilitate timely public health responses to outbreaks. Future research should focus on optimizing these techniques for routine use in food safety laboratories and exploring novel approaches for pathogen control.
