Minimizing the risks of Vibrio bacteria in farm-raised oysters grown in intertidal elements of the Delaware Bay

New Jersey’s oyster farms are concentrated on the extensive intertidal sand flats of the lower Delaware Bay where they are exposed twice daily during low tide. The project manager conducted a preliminary study to test whether this result applies to mid-Atlantic intertidal environments.

The project did not reveal a significant difference between levels of total and pathogenic Vibrio between subtidal and intertidal oysters, nor was there a significant increase in Vibrio burdens over the time course of low-tide exposure. This initial result suggests that the relationship between grow-out conditions and Vibrio levels in oysters is not as straightforward as previously thought, and highlights the need for locally relevant aquaculture practices to minimize the risk of Vibrio illness.
