General information on Vibrio and DEC’s current Vibrio control plan

Vibrio bacteria naturally live in certain coastal waters and are present in higher concentrations between May and October when water temperatures are warmer. About a dozen Vibrio species can cause human illness, known as vibriosis. Most people become infected by eating raw or undercooked shellfish, particularly oysters.

You can submit your water temperature and salinity reports in the Environmental Health Shellfish Portal.
