Evaluation of four disinfectants under poultry grow-out conditions using contact agar sampling technique.
Four commercial disinfectants used in poultry house sanitation procedures were evaluated for efficacy using a specialized petri dish (Rodac plate) for contact sampling. The samples were taken from a variety of surface materials commonly found in poultry rearing facilities. Two media were used, one for bacteria and one for mold. Predisinfection samples were taken following removal of chickens and litter. Postdisinfection samples were taken 4 hr after room treatment with a high pressure spray apparatus. The most effective disinfectant for reducing bacteria colony counts was a product that contained glutaraldehyde. The other products, ranking in order of efficacy for bacteria, contained cresylic acid, iodophors, and a combination of quaternary ammonium compound and formaldehyde. The most effective disinfectant for reducing mold colony counts was the product containing cresylic acid. The other products, ranking in order of efficacy for mold, contained iodophors, the combination of quaternary ammonium compound and formaldehyde, and glutaraldehyde. The most effective overall disinfectant was the cresylic acid product.
