Abstract
Survival and viability of ten serotypes of salmonella isolated from seafoods at refrierated and frozen srorage temperatures and at different pH values were studied. Salmonella serotypes were inoculated in two concentrations in shrimp, shrimp homogenates, froglegs and frog homogenates. All the serotypes of salmonella survived during refrigerated storage(2 to 5 degree C). Duration of survival was propotional to the initial concentration of inoculation. Heavily inoculated samples showed the presence of salmonella upto five months in the muscle portions of prawns and froglegs, while survival in respective homogenates were upto three months. Lower populatons, S. anatum, S. cubana, S. enteritidis and S. senftenberg survived at 60 degree C by one min heating. Above 80 degree C none survived by five min heating. All the serotypes tested were sensitive to pH below 5.0 and above 7.5.
