Abstract: Products derived from modern biotechnology, and in particular when issued from
transgenesis technique (often called ‘genetically-modified organisms’– GMOs), are rigorously
assessed by governments to ensure high safety standards for the environment, human food, and animal feed. Over the last forty years, the Organisation for Economic Co-operation and
Development (OECD) has developed tools and guidance for assisting countries in their
risk/safety assessment of transgenic plants, animals and micro-organisms. The new challenges raised by genome-edited products regarding their safety regulation are also discussed at OECD.
