Bacteria in the genus Vibrio can cause illness to people through eating of contaminated seafood, or exposure to contaminated water. Vibrios occur naturally in the Chesapeake Bay, but their abundance varies with water temperature, salinity and other factors. We assessed the potential effects of climate change on the future abundance of three Vibrios in the Chesapeake Bay using outputs from four statistically downscaled climate models. We show that abundance of Vibrios in the water column, and in oysters, may increase as temperatures warm and flow regimes change. In addition, the seasons of highest risk may last longer, compared to the present day. This suggests that Vibrio-related illnesses in the Chesapeake Bay region may increase in the future, unless current management measures can adapt.
