Evaluation of four disinfectants under poultry grow-out conditions using contact agar sampling technique
Abstract:
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.
Insights
Four commercial disinfectants were tested for poultry house sanitation. Cresylic acid proved most effective overall for reducing both bacteria and mold colony counts on various surfaces.
Area of Science:
- Veterinary Science
- Microbiology
- Environmental Hygiene
Background:
- Poultry house sanitation is crucial for disease prevention and animal welfare.
- Effective disinfectants are needed to control microbial contamination in poultry environments.
Purpose of the Study:
- To evaluate the efficacy of four commercial disinfectants against bacteria and mold on poultry house surfaces.
- To determine the overall best disinfectant for poultry facility sanitation.
Main Methods:
- Contact sampling using Rodac plates on various poultry house surfaces.
- Testing two types of culture media for bacteria and mold enumeration.
- Collecting pre- and post-disinfection samples after high-pressure spray application.
Main Results:
- Glutaraldehyde-based disinfectant was most effective against bacteria.
- Cresylic acid-based disinfectant showed the highest efficacy against mold.
- The cresylic acid product was the most effective overall disinfectant.
Conclusions:
- Disinfectant choice significantly impacts microbial load reduction in poultry houses.
- Cresylic acid demonstrates superior broad-spectrum antimicrobial activity for poultry sanitation.
- Targeted disinfectant selection is essential for effective poultry farm hygiene.
