Summary: Foodborne pathogens have significant effects on human health and the economy. Various foodborne pathogens, including Salmonella spp., Escherichia coli, Staphylococcus aureus, Shigella spp., Campylobacter spp., and Listeria monocytogenes, are found in agricultural products, dairy products, animal-derived foods, and the environment. These pathogens in different types of food and water can cause life-threatening diseases and develop resistance to antibiotics. Traditional detection methods are time-consuming, labor-intensive, and expensive, necessitating the urgent need for fast detection methods. Electrochemical biosensors provide accurate and reproducible results for the quick detection of foodborne pathogens in food and the environment. This paper provides a comprehensive overview of electrochemical biosensors for the detection of foodborne pathogens, discusses risk analysis methods and control measures, and highlights recent research progress and future possibilities.
