Fish-borne zoonotic diseases, particularly those caused by bacterial and parasitic agents, constitute a serious threat to global health. By focusing on the identification of pathogens shared between fish and humans (including Salmonella spp., Campylobacter spp., and the parasites Sarcocystis and Balantidium), this research underscores the critical role of these agents in the emergence of human disease. The significance of this work is amplified by rising global seafood consumption, the expansion of industrial aquaculture, and the inadequacy of regulatory and surveillance systems in many countries. Understanding these diseases is essential not only for preventing infectious outbreaks, but also for reducing the economic burden associated with treatment costs and disruptions to the food supply chain. Through analysis of epidemiological data, transmission routes (consumption of contaminated fish; direct contact with water or fish), and diagnostic challenges, the study proposes integrated approaches to contain these diseases. Practical measures include strengthening aquaculture surveillance, implementing more rigorous hygiene protocols, educating local communities, and developing rapid diagnostic methods. At the global level, coordination among public health and food-related organizations (e.g., WHO and FAO) to establish international standards, facilitate information exchange, and support developing countries in implementing effective monitoring systems is pivotal to preventing epidemics. Emphasizing the inseparable links among animal health, human health, and aquatic ecosystems, this research highlights the need to translate the “One Health” concept into an operational framework. The findings represent not only a substantive step toward mitigating zoonotic risks, but also a bridge between science, policy-making, and coordinated global action to safeguard future generations. The value of this study lies in providing an evidence-based roadmap that transcends geographic boundaries and policy silos, thereby strengthening humanity’s resilience against emerging threats.
