Integration of National Chemical Hazards Monitoring, Total Diet Study, and Human Biomonitoring Programmes for Food Safety Exposure Assessment in Singapore

Abstract

Food safety and food security can impact the quality of human life, and these two aspects are interrelated alongside many influencing external factors. Global stressors such as climate change, recent pandemic, and geopolitical tensions have demonstrated tangible impacts on food security and safety. Food and food system innovation is a key strategy towards feeding the world in a more sustainable and climate-resilient manner. This paper highlights the use of a science-based risk assessment and management in Singapore’s food safety system, specifically in the integration of exposure assessment approaches to support evidence-based food safety risk analysis and decision-making. The use of complementary top-down and bottom-up exposure assessment approaches through the market monitoring programme, total diet study and human biomonitoring forms a comprehensive integrated exposure assessment strategy which can ultimately inform policy and measures in ensuring and securing a supply of safe food. The discussion on such application for chemical food safety in Singapore offers additional insights into the synergistic inter-relationships contributing to the exposure assessment associated with chemicals in food.
