Author(s): Benjamin R. Robinson, Dennis J. D’Amico Hydrogen peroxide (H2O2) has a long history of use as an antimicrobial in the dairy industry to preserve raw milk. The effect of H2O2 on the survival of Listeria monocytogenes on the surface of Queso Fresco (QF) and the degradation of H2O2 on cheese during storage and in dip solutions following successive treatments were determined. Treatment of...
