Description of key information
Mutagenic potential of FAT 40034 was evaluated in two different bacterial reverse mutation assays.
In a key study conducted by Haroz et al. (1978), Salmonella typhimurium strains TA 1535, TA1537, TA 98 and
TA 100 were exposed to the test substance with and without metabolic activation. Under the conditions
employed and using the doubling of the spontaneous reversion rate as a criterion of mutagenicity, FAT 40034/A
did not induce significant reverse mutations with and without metabolic activation. Hence, based on the findings
of the study, it can be concluded that FAT 40034 was not mutagenic in the bacterial reverse mutation assay.
In a supporting study conducted by Arni, P. (1979), FAT 40034/B was tested for mutagenic effects on
histidine-auxotrophic mutants of Salmonella typhimurium which included TA 98, TA 100, TA 1535, TA 15 37
and TA 1538. The investigations were performed with the following concentrations of the trial substance with
and without microsomal activation: 15, 45, 135, 405 and 1215 microg/0.1 ml. A repetition of the experiments
was performed with the concentrations of 25, 75, 225, 675 and 2025 microg/0.1 ml. In these experiments tests
on Strain TA 1538 were included. In the experiments performed with and without microsomal activation,
comparison of the number of back-mutant colonies in the controls and the cultures treated with the various
concentrations of FAT 40034/B revealed no marked deviations. Based on the findings of the study, no evidence
of the induction of point mutations by FAT 40034/B or by the metabolites of the substance formed as a result of
microsomal activation was detectable in the strains of S. typhimurium used in these experiments. Hence, FAT
40034/B was determined to be non-mutagenic in the bacterial reverse mutation assay.

Referenceopen allclose all
Under the experimental conditions defined in the protocol, and employing a doubling of the spontaneous reversion rate as a criterion of mutagenicity, product FAT 40034/A was not mutagenic for Salmonella ty-phimurium strains TA 1535, TA1537, TA 98 and TA 100.
The lack of evidence for mutagenicity existed both in the absence and presence of a liver microsomal enzyme preparation (S9-mix) from male rats pretreated vith Aroclor 1251 and over a concentration range of 0.2 to 2000 µg of product per Petri dish.
