Efficacy of teat dips containing a hypochlorous acid germicide against experimental challenge with Staphylococcus aureus and Streptococcus agalactiae.
Two teat dip formulations containing sodium dichloroisocyanurate, which released hypochlorous acid (2800 ppm) as the active ingredient, were tested for efficacy against new Staphylococcus aureus and Streptococcus agalactiae IMI using an experimental challenge model. Product 1 reduced the number of new Staph. aureus IMI by 73.6% and reduced the number of new Strep. agalactiae IMI by 65.1%. Product 2 reduced the number of new Staph. aureus IMI by 69.0% and reduced the number of new Strep. agalactiae IMI by 63.5%. No adverse effects on teat skin condition were observed over the course of the studies.
