The harmful bacteria Vibrio parahaemolyticus is often present in the Chesapeake Bay in the summer. Knowing when and where to expect Vp may help people to avoid a dangerous exposure, especially for those with compromised immune systems. The empirical models relating temperature and salinity to Vp concentration in oysters were developed and provided by the US FDA and represent expected levels at time of harvest. More information on the models may be found here.

These maps are experimental and show a prediction of the concentration of V. parahaemolyticus in Oysters harvested from Chesapeake Bay.
