September 9, 2020 — LSU researchers have launched a project that aims to give Louisiana oyster harvesters a way of detecting whether waters contain viruses or bacteria that can cause some people to get sick when they eat the shellfish raw or undercooked.
“This project is meant to decrease the number of people getting sick and also decrease oyster recalls,” civil and environmental engineering professor Zhiqiang Deng said in a news release. “The project will aid in the economic development of Louisiana by reducing costly oyster ground closures and recalls, thereby increasing oyster production.”
One-third to 40% of the oysters harvested in the U.S. come from Louisiana waters, more than any other state. The industry employs about 4,000 people in the state, with an economic impact of $317 million annually, according to the Louisiana Seafood Promotion & Marketing Board.
About a fifth of all oysters harvested in Louisiana come from the Terrebonne Basin, an area that includes all of Terrebonne and parts of Lafourche and several other parishes between the Acthafalaya River and Bayou Lafourche, state figures show.
