Results of recent research support the continuous use of quaternary ammonium compounds as antimicrobial agents in poultry processing facilities, when and where needed, while avoiding any negative impacts on biological treatment systems and the environment.

The research focused on the assessment of biological nitrogen removal in poultry processing treatment, and the results will help design BNR systems for efficient treatment of wastewater containing QACs.

The outcome of the study, conducted at the Georgia Institute of Technology and funded by the U.S. Poultry & Egg Association, lends support to the idea that the effectiveness of biological processes for the degradation of QACs should be further evaluated in order to capture process variability across the entire poultry processing industry, according to the researchers.
