Interpretive Summary:

Technical Abstract: Peracetic acid is a therapeutic agent used for disinfection, but it must be investigated in order to mitigate diseases without harmful effects to the fish. These agents should not leave dangerous residues in the environment in order to successfully contribute to sustainable aquaculture. The aim of our study was to compare the effectiveness of six commercial PAA products with different molecular PAA: H2O2 ratios to reduce bacterial growth of A. salmonicida and Y. ruckeri, and to determine effective concentrations and exposure times. All products reduced CFUs of A. salmonicida and Y. ruckeri. Products with a higher concentration of PAA (versus H2O2) did inhibit growth better than products with lower PAA and higher H2O2 concentrations; H2O2 is not the driving force in the reduction of A. salmonicida and Y. ruckeri growth by PAA in vitro. The practical application of the products with high PAA concentration should be prioritized if these pathogens are diagnosed.
