Ocean warming and climate change will be the possible factors which can impact on food contamination and foodborne diseases. And the comprehensive strategies are required in consideration of changes in the nature and occurrence of food safety hazards which are being provoked by climate change and its variability.

Long term data from the sanitary survey and monitoring for various hazardous elements in seafood and its surrounding marine environment for several decades were analysed to evaluate the effect of climatic factors on various food safety risks to suggest their counter measures and supplementary element for the national level safety control strategy in Korea.

Level of pathogenic bacteria such as Vibrio vulnificus and occurrence of marine biotoxin in seafood are easily affected by climate changes and seafood safety especially for raw consumption is greatly relevant to these alterations in Korea. The period of PSP toxins occurrence extended from 15 weeks to 31 weeks in the south coast of Korea and the affected area has also expanded since 2000. Vibrio vulnificus was also affected by these changes in infections ratio and period. In addition the various changes may interact with other stressor factors to impact on food hazard elements.

The issue of vulnerability of seafood to climate change is considered at national level but the effective strategy is not well established due to the limited scientific data availability and collaboration in Korea. Country should respond promptly to requirements to solve the inter-related issues, which includes updating good hygiene practice guidance and monitoring and surveillance programmes to address emerging hazards arising from climate change, collaboration for the global approach to epidemiological surveillance and risk assessment, strengthened communication with the public, investment in scientific and technical capacities and sharing of data coming out of monitoring and surveillance.
