Based on this recommendation, genotoxicity and mutagenicity may be assessed by the micronucleus test and comet assay, which are suitable to evaluate DNA damage [ 94, 127]. Although these methods are not yet validated, authorities such as the EFSA promote them. They suggest including them in test strategies to assess genotoxicity in vivo in an organ other than bone marrow or liver.
