Summary

Standard methods for the removal or inactivation of disinfectants from reaction mixtures are often unsatisfactory when dealing with high concentrations of particulate organic matter. A method employing freeze-drying was developed to eliminate residual disinfectant activity from reaction mixtures. Following the addition of volatile chemicals to sterilized cattle slurry, samples were removed from the mixture, freeze-dried and the dried material was reconstituted with diluent containing Escherichia coli as the test microorganism to determined if the volatile chemicals had been removed. Twelve chemicals and one commercial disinfectant (Virkon S) were evaluated at different concentrations.
