According to scientific opinion of EFSA’s Scientific Committee (SC), international approaches to risk assessment can also be applied to engineered nano materials (ENM). But in practise due to lack of validated test methodologies make risk assessment of specific nano products very difficult.

According to SC, there are still some specific recommendations like investigating the interaction and stability of ENMs in food and feed, in the gastro-intestinal tract and in biological tissues, developing and validating routine methods to detect, characterise and quantify ENMs in food contact materials, food and feed and developing, improving and validating test methodologies to assess toxicity of ENMs (including reliability and relevance of test methods)

EFSA continue their research about nano foods. Due to it is very new technology, there are severalpoints to research and clarify.
