Abstract Mycobacteriosis is an important bacterial disease of freshwater, brackish‐water, and marine fishes. In addition to affecting many species of wild and cultured fish, the aquatic mycobacterial species present a potentially important zoonotic risk to humans. Reduction or elimination of the causative pathogen from an aquarium or aquaculture facility is therefore paramount. This study examined a variety of commercially available disinfectants for their efficacy in reducing or eliminating Mycobacterium marinum . In this study, ethyl alcohol (50% and 70%), benzyl‐4‐chlorophenol/phenylphenol (1%), and sodium chlorite (mixed as 1:5:1 or 1:18:1 [base : water : activator]) were the most effective disinfectants evaluated; each reduced or eliminated the number of detectable M. marinum within 1 min of contact time. Sodium hypochlorite (50,000 mg/L) was moderately effective but required a minimum contact time of 10 min to reduce bacterial counts. Ethyl alcohol (30%), N ‐alkyl dimethyl benzyl ammonium chloride (1:256; two formulations), and potassium peroxymonosulfate– sodium chloride (1%) did not substantially reduce bacterial counts even after 60 min of contact time.
