In a
subsequent study, Hwang and Beuchat (1995) reported
that a lactic acid and sodium benzoate solution enhanced
the rate of inactivation of Salmonella on chicken skin during
refrigerated storage. In addition, Mulder et al. (1987)
found lactic acid (1%) and hydrogen peroxide (0.5%) resulted
in 4-log reductions in Salmonella on experimentally
inoculated carcasses or in naturally occurring Salmonella
infections. Although many reported treatments have been
effective in decreasing bacterial contamination, many of
these procedures used heated water or organic acid immersion
treatments, which result in discoloration and deterioration
of the carcass quality. In addition, some of the
organic acids tested were not generally recognized as safe
(GRAS) and, thus, could not be applied commercially
