ResumoA postmilking teat dip containing chlorous acid-chlorine dioxide was evaluated by experimental challenge and in two herds under natural exposure.The test product had an efficacy of 78.9% against Staphylococcus aureus and 52.5% against Streptococcus agalactiae in the experimental challenge trial.The product was compared with a 1% iodine product in a 15-mo natural exposure study.Postdipping with chlorous acid-chlorine dioxide reduced incidence of udder infection by major mastitis pathogens 36.1 % when data were combined from the two herds.The 1% iodine and the chlorous acidchlorine dioxide products were not equivalent for major mastitis pathogens; the test product was more effective.Incidence of udder infection by environmental mastitis pathogens was reduced 36.8% in both herds combined.Efficacy of the two teat dips was equivalent for environmental pathogens.
