The impact of zoonotic diseases on the food production chain: A review of key challenges and prevention strategies

Abstract

Zoonotic diseases pose a major challenge to public health and the safety of food production systems, as pathogens can be transmitted from animals to humans through direct contact, consumption of animal products, or exposure to contaminated environments. The impacts of zoonoses are broad, including increased morbidity and mortality in humans, reduced livestock performance and productivity, economic losses, and social and environmental implications. The complex relationship between humans, animals, and ecosystems demands integrated, comprehensive, and evidence-based control efforts. This review aimed to synthesize recent scientific findings on the impacts of zoonotic diseases along the food production chain, identify risk factors contributing to pathogen spread, and assess various prevention strategies that have been implemented in various contexts. The literature review covers human health, animal welfare, economic, social, and environmental dimensions, with an emphasis on biosecurity, vaccination and animal health interventions, food safety regulations, and the use of technological innovations such as early detection systems and product traceability. The analysis shows that consistent implementation of biosecurity, appropriate veterinary medical interventions, hygienic food processing practices, and technology-based monitoring systems can significantly reduce the risk of zoonotic transmission. A cross-sectoral approach that adopts the One Health principle has been proven to enhance synergy between human health, animal health, and the environment, making risk mitigation efforts more effective and sustainable. Going forward, research is recommended to focus on developing adaptive vaccines, innovating disease detection technologies, improving education for livestock farmers and food workers, and evaluating regulatory policies to strengthen production chain security. This comprehensive approach is expected to strengthen zoonotic control systems, reduce health and economic impacts, and support global food security.
