Occurrence of Salmonella in Minimally Processed Vegetables

Vegetables that have been physically altered from its original state but remain in its fresh state are considered minimally processed. These vegetables are subjected to one or more physical changes (processes of washing, peeling, slicing and cutting), which make them ready for consumption. However, in the dicing step occurs the release of internal cellular fluids, rich in nutrients, which allow...

Inactivation of enteric viruses in minimally processed berries and herbs.

Several hepatitis A virus (HAV) and human norovirus (HuNoV) outbreaks due to consumption of contaminated berries and vegetables have recently been reported. Model experiments were performed to determine the effectiveness of freeze-drying, freeze-drying combined with heating, and steam blanching for inactivation of enteric viruses that might be present on the surface of berries and herbs. Inacti...

Biphasic thermal inactivation kinetics in Salmonella enteritidis PT4.

The thermal inactivation kinetics of Salmonella enteritidis PT4 between 49 and 60 degrees C were investigated. Using procedures designed to eliminate methodological artifacts, we found that the death kinetics deviated from the accepted model of first-order inactivation. When we used high-density stationary-phase populations and sensitive enumeration, the survivor curves at 60 degrees C were rep...
