Abstract
Abstract A mastitis controlling method and composition based upon anionic surfactants of the formula R-AOx-M+ which generally includes organic sulfonates, sulfonic acids, phosphonates and phosphates, the composition being maintained in a pH range of 2.0 to 5.0 (preferably 2.1 to 4.0, and most preferably 2.5 to 3.5). Rapid kill of mastitis-causing gram positive and gram negative microorganisms is achieved in the practice of the instant method.
