Foodborne Pathogens & Public Health

Foodborne pathogens continue to pose significant global public health challenges, causing millions of illnesses annually and imposing major economic burdens. Research in this area focuses on emerging and re-emerging pathogens, antimicrobial resistance, transmission dynamics, and innovative detection technologies. Traditional hazards such as Salmonella, Listeria, E. coli, and Campylobacter remain priorities, while viral and parasitic pathogens are gaining increased attention. Advances in molecular diagnostics, including whole-genome sequencing, biosensors, and rapid point-of-care assays, are transforming outbreak investigation and source-tracking capabilities. Public health measures, including improved surveillance systems and integrated One Health approaches, are crucial for preventing foodborne infections across agriculture, food processing, and retail sectors. The field also explores risk communication, regulatory frameworks, and consumer behavior, recognizing that prevention requires coordinated action across the entire food chain. As global trade, climate change, and population growth continue to influence pathogen distribution, new strategies—such as predictive analytics, blockchain traceability, and smart packaging—are essential for maintaining safe and resilient food systems.
