The map visualizes seafood mislabeling prevalence across 14 U.S. metropolitan areas, with rates ranging from 18% in Seattle to 52% in Southern California. Each location highlights specific cases-such as “snapper” substituted for red snapper or “tilapia” sold as higher-value fish-based on DNA barcoding tests conducted by Oceana. Additional samples were collected in Maryland, Minnesota, New York, New Mexico, Virginia, and West Virginia, underscoring national scope.
