Ensuring the safety of the food supply relies upon an understanding of the relationships between the components of the supply and their interaction with, and influence on hazards present in food. Clients need to consolidate, evaluate, and interpret the diversity of data and information available from the perspective of safety and risk. The complexity of the food supply makes this process almost impossible without the application of quantitative modelling to describe the relationships in the food chain that determine the risks to the consumer from contaminated food (whether that be microbial or chemical contamination). Clients need to leverage to power of models to explore relationships not readily observable, and to determine cost-effective risk-mitigation options that benefit consumers.

Our team brings a rare combination of expertise in microbiology, toxicology, statistics, computer modeling, engineering analysis, software development, and decision-support tool design. RSI also has a strong track record in creating risk assessment tools for use by others, helping to extend and share risk assessment capabilities across the food sector.
Why RSI is trusted to deliver
RSI is recognised as leaders in food safety risk assessment. RSI has worked with clienst around the world and has developed over 200 (?) food safety risk assessments for regulators and food industry. RSI has worked with UN FAO and WHO for over a decade supporting them in their pursuit of a safe food supply for all, and continues to provide risk assessment expertise to this important endeavour. RSI are the main developers, and continue to support tools available to the food safety risk assessment community including FDA-iRISK, and the FSTools.com suite presented by FAO/WHO.
Understanding, managing, and communicating risk

Why this image?
Food safety assessment ensures that what reaches our kitchens is not only nourishing, but also safe. The image of fresh fruits, vegetables, and bread neatly arranged on a kitchen counter beside a brown paper bag reflects the quiet confidence people place in the food they buy and prepare. It’s a reminder that safety is assumed—not questioned—thanks to the behind-the-scenes work of rigorous scientific evaluation, risk analysis, and regulatory oversight. RSI supports this essential trust by providing the evidence and expertise that underpin every safe meal.
