June 20, 2025 — Last week, the Texas-based firm SeaD Consulting released the results from a study that shook the culinary scene in Charleston, South Carolina. A team of undercover testers had paid visits to randomly selected seafood restaurants around the city and used on-the-spot genetic testing to determine whether the shrimp came from local waters. The results were shocking in a town that prides itself on abundant fresh catch: Forty out of the forty-four restaurants it tested, the company reported, served imported, farm-raised shrimp.
Charleston isn’t the first market the company has scrutinized since ramping up its testing efforts last August. SeaD has also visited New Orleans, Savannah, Tampa–St. Petersburg, and Wilmington, North Carolina, among others. Of those cities, New Orleans fared best, with only 13 percent of restaurants misrepresenting their shrimp (largely due to more stringent food labeling laws in Louisiana, according to SeaD). Savannah and Wilmington each tallied 77 percent inauthenticity. In Tampa, just two restaurants of forty-five were serving Gulf shrimp, the firm reported.
Since the Charleston bombshell dropped, the plot has thickened. Local shrimpers have come forward to vouch for clients who buy from them, since SeaD didn’t reveal the names of the forty establishments that served imported shrimp. And the S.C. Shrimpers Association has announced a lawsuit against those unidentified restaurants (referring to them as “John Doe Restaurants” in the complaint) in which it accused them of false advertising and in violation of South Carolina’s Unfair Trade Practices Act.
With the industry still reeling, we chatted with SeaD founder Dave Willams and his daughter, chief operations officer Erin Williams, to find out exactly how the team conducted its testing, if the Charleston results surprised them, and what changes they hope to see in the shrimping and restaurant industry. And, yes, they know where they’re headed next, but they’re not saying.
