Oyster safety improvement ways to be researched

Auburn University has received a grant from the federal Government to develop a project to help ensure that farmed oysters bound for the premium half-shell market are as safe as possible for human consumption.

The grant, of USD 456,646, is one of 13 competitive food safety awards that USDA’s National Institute for Food and Agriculture has announced as part of its Agriculture and Food Research Initiative. With this aid, a team from Auburn University will conduct a three-year study to determine whether an oyster farm’s geographic location, handling practices and choice of equipment affect Vibrio levels in farm-raised oysters.

These bacteria occur naturally in warm ocean waters, such as the Gulf of Mexico. Certain vibrio species, most notably Vibrio vulnificus, can cause foodborne illnesses in people who eat raw or undercooked shellfish.

Through the project, led by Auburn University marine scientist Bill Walton, valuable data will be generated for Gulf Coast oyster farmers, who focus on producing exceptional oysters for high-end markets, such as upscale restaurants that offer the farmed bivalve mollusks on the half shell.

“Our findings will help farmers understand and manage their preharvest production techniques to minimize the risk of foodborne illness in consumers. These folks absolutely want to provide the safest product they can, so this is critical information for these farmers,” Walton stresses.

To achieve the superior product the market demands, farmers grow their oysters in underwater baskets or cages that float above the ocean floor. Once a week, they raise the baskets out of the water and allow the oysters to air-dry. That practice prevents barnacles, seaweed and other undesirable organisms from attaching to and marring the oysters.

Though the air-drying is process is crucial to product quality, it is not risk-free, said Vicki Pruente, an Auburn doctoral student assisting Walton on the project.

“The frequent handling exposes the oysters to elevated air temperatures and also interrupts filter feeding, and those conditions cause Vibrio levels to rise,” Pruente explains.

Once the baskets are lowered back into the ocean, Vibrio levels gradually subside, but questions remain, Walton says.

“In our trials, we will look at how long after the oysters are resubmerged the Vibrio levels return to naturally occurring levels,” he states. “Our results will help farmers as they evaluate their production techniques.”

To establish the impact of geographic location on Vibrio levels, Walton and Pruente will conduct the research simultaneously at the Auburn University Shellfish Lab’s oyster research farm in Grand Bay, Alabama, and at a farm in Cedar Island, North Carolina.
