Conclusions:
Interpretation of results (migrated information): negative
Executive summary:

In conclusion, it can be stated that during the study described and under the experimental

conditions reported, the test item did not induce micronuclei as determined by the

micronucleus test with bone marrow cells of the mouse.

Therefore, FAT 40'576/A is considered to be non-mutagenic in this micronucleus assay.
