Comprehending the risk of foodborne and waterborne disease outbreaks: Current situation and control measures with Special reference to the Indian Scenario.

Background: Foodborne and waterborne diseases and outbreaks are a neglected public health issue worldwide. In developing countries, diarrheal disease caused by foodborne and waterborne infections is a major cause of ill health. There is a lack of information on foodborne pathogens, their transmission routes, outbreaks, and related mortalities, due to the absence of a robust disease surveillance system and adequately equipped laboratories. Although hygiene practices are much better in Western countries, the widespread use of preserved and raw food items is a cause of concern. Consequently, the occurrence of foodborne diseases is not rare in these countries either. WHO has recently released the 'Global Strategy for Food Safety 2022-2030', addressing the emerging challenges, new technologies, and innovative approaches to strengthen food safety systems and enhance laboratory capacity for foodborne disease surveillance. Foodborne outbreaks are a huge challenge in India. Malnutrition, anemia, hookworm and enteric infections, are the predominant cryptic health conditions among children in rural and tribal areas, leading to severe consequences, including death, and posing a substantial threat to public health. Combating such events with adequate food safety and hygiene practices is achievable. Systematic collection of data can help to develop food safety policies that could reduce the burden of foodborne diseases. Objective: This review aims to examine the current situation of foodborne and waterborne diseases, identification of the factors contributing to their occurrence and outbreaks, and defining the gaps in control measures, challenges, and potential solutions in improving the public health system. Methods: Strengths, weaknesses, opportunities, and threats (SWOT) analysis was made based on the literature review of foodborne and waterborne infections to assess the current situation and to identify knowledge gaps. Finding: SWOT analysis showed the strength and gaps in the different national initiatives analogous to the global programs. Though, Integrated Disease Surveillance Programme (IDSP), Food Safety and Standards Authority of India (FSSAI), the core Government missions, independently generate substantial information, sporadic and outbreak cases of diarrhea still prevail in the country due to the absence of a systematic national surveillance system. Recently, many government initiatives have been made through Sustainable Development Goals (SDGs), G20 goals, etc. However, potential threats such as risk of zoonotic disease transmission to humans, emerging infections and antimicrobial resistance (AMR), and unauthorized activities in the food sector pose a big challenge in safeguarding the public health. Conclusion: Maintenance of global food safety requires a systematic analysis of present situations, identification of existing shortcomings, and targeted efforts toward prevention of infections. The ongoing G20 mission and the SDGs for 2030 represent significant strides in this direction. To have pathogen-free animals and supply of contamination-free raw foods is impractical, but, mitigating the prevalence of zoonotic diseases can be accomplished by rigorously enforcing hygiene standards throughout the food production chain. A crucial requirement at present is the implementation of integrated laboratory surveillance for foodborne and waterborne infections, as this will provide policymakers and stakeholders all the evidence based scientific information. This system will facilitate efforts in minimizing the risks associated with foodborne and waterborne infections.
