Abstract
The ability of Listeria monocytogenes to survive and grow in fish at refrigerated condition
was studied. Fresh, white sardine (Kowala coval) were washed and inoculated with
L monocytogenes (NCTC 1994) at a level of 104 cfu.g"1. The inoculated fish were kept at
room temperature (28±20C) for 6 h and then stored at refrigerated condition (4±10C). The
fish was found to have a load of 105 cfu.g"1 of L. monocytogenes after the temperature abuse.
Though there was a minimal increase in the count during the first two days of refrigerated
storage, a slight reduction in counts was observed on the 4th day of chilled storage and
thereafter the counts did not show appreciable change. The results suggest that chilling
does not have a significant effect on the control of L. monocytogenes in fish and there is
a possibility of contaminated seafood acting as a vehicle of infection.
