Doubling Times for Vibrio parahaemolyticus in Delaware Bay Oysters

Doubling Time of Vibrio parahaemolyticus (Vp) in Oysters from Delaware Bay

Vibro parahaemolyticus has one of the fastest growth rates of all estuarine bacteria, and the population can replace itself, or double every hour at 90°F. This product uses local NWS gridded forecasts of air temperature from the National Digital Forecast Database to force a statistical growth rate equation (USFDA 2005) for Vp. The spatially explicit graphical display allows users to determine where and when the highest doubling times will occur every hour, out to 7 days in advance to plan harvest and refrigeration strategies.
