Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information):
negative

EDTA-CaNa2 did not induce mutagenicity in the Ames test using strains TA97 and TA102
Executive summary:

A mutagenicity test was carried out with 28 food additives including EDTA-CaNa2 using Salmonella typhimurium strains TA97 and TA102 with and without metabolic activation. No mutagenicity was observed.
