Urine samples from 12 humans receiving oral therapeutic doses of nitrofurantoin for urinary infection were mutagenic for S. typhimurium strain TA 100 and nonmutagenic for strain TA 100-FR1. Mutagenic activity of the urine was not increased by treatment with .beta.-glucuronidase. Spot mutation assay of the chromatogram of urine revealed that the mutagenic activity of the urine was due to unmetabolized nitrofurantoin.
