EFSA clarifies aim of 90-day GMO feed tests
The European Food Safety Authority (EFSA) has clarified the objectives of 90-day feeding studies on whole genetically modified food and feed, and provided instructions on how to apply its existing guidance on study design and analysis. The statement comes as a separate EU research project on GM maize feeding trials concluded that its results validate the EFSA’s guidance in this area. Since 2013, 90-day feeding trials have been mandatory for the authorisation of GM plants. The EFSA outlines two possible scenarios, depending on whether a preceding analysis has identified a potential risk or not. Its advice includes preparation and analysis of diets, dose levels for various crops, sample sizes, endpoint selection, and interpretation of results.
