title: The effects of contamination on biological monitoring.
abstract: We investigated the frequency and patterns of biological-monitoring-test contamination and the effect of contamination on the growth of test organisms. Overall, the contamination rate was 0.81%, but the rate of contamination varied significantly by sterilization method. Contamination did not appear to inhibit growth of test organisms.
