Reducing levels of Listeria monocytogenes contamination on raw salmon with acidified sodium chlorite.

摘要: The antimicrobial activity of acidified sodium chlorite (ASC) against Listeria monocytogenes in salmon was studied. Raw (whole fish and fillets) inoculated with L. (10(3) CFU/cm2 or 10(4) CFU/g) were washed ASC solution (50 ppm) for 1 min stored at -18 degrees C month salmon) ice 7 days (fillets). populations determined whole after frozen storage fillets on 1, 3, 5, storage. A wash followed by glazing did not reduce the skin during However, resulted an reduction 0.5 log CFU/g fillets. increased slowly storage, but growth these retarded ice. By day 7, 0.25 units smaller 0.62 that had been than control Treatment also reduced total plate counts (TPCs) 0.43 0.31 TPCs decreased gradually 5 ASC-treated samples lower those controls any point study.
