While the Food and Drug Administration is busy tamping down concern over its oversight of processed foods, an investigation in Chicago has identified another gap in its programs: ensuring fish are accurately labeled. The Chicago Sun Times tested fish labeled as red snapper around the city, and found that most of it was cheaper tilapia. None were red snapper. There's reason to believe the mislabeling is widespread. A recent national survey found 37 percent of fish tested were mislabeled.
