Efficacy of a washer-pasteurizer for disinfection of respiratory-care equipment.
We evaluated the efficacy of a commercial washer-pasteurizer. Carriers were inoculated with 10(4) to 10(6) test organisms and pasteurized at 170 degrees F for 30 minutes. Pasteurization eliminated all test organisms with the exception of Bacillus subtilis spores. Pasteurization appears efficacious for the disinfection of respiratory-care equipment and could result in a cost savings of approximately $30,000 per year.
