Abstract

The purpose of this study was planned out to evaluate the effectiveness of Acidified SodiumChlorite (ASC) on the viability of L. monocytogenes by contaminating Salmon fish sampleswith 1x108 cfu/g of L. monocytogenes, followed by dipping the contaminated samples indifferent concentrations of ASC 250, 500 and 1000 ppm. The samples were stored inrefrigerator at ° 4c to be examined for L. monocytogenes count at Zero day ,First, third, fifthand seventh day of refrigeration storage. The results revealed that the counts ofL.monocytogenes in salmon fish samples dipped in different ASC concentrations of 250, 500and 1000 ppm in zero (treatment day), were 1x107,3.8x106 and 1x106 cfu/g respectively, andin the first day after storage the counts were 8x106,1x106 and 1x105 cfu/g respectively while inthe third ,fifth and seventh day the counts were reduced to be <10 cfu/g.
