Efficacy Comparisons of Disinfectants Used by the Commercial Poultry Industry

Abstract

Several commercially available disinfectants used by the poultry industry were evaluated for their effectiveness against selected bacteria and viruses. When tested in the absence of organic matter, most disinfectant products were effective at the manufacturer's recommended level within 10 min of contact time. However, when organic matter was present, longer contact times and/or higher disinfectant dosages were needed to maintain effectiveness. Pseudomona aeruginosa and infectious laryngotracheitis virus were very resistant organisms in the presence of organic matter. Evaluation of disinfectant efficacy against several microbials in the absence or presence of organic matter was highly practical, flexible, and reproducible.
