NY State Attorney General has issued a report about mislabeled fish in NY State–the highest percentage being in NYC. Appendix A and B lists the stores that were found to be mislabeling. Most of these are chains (including Whole Foods and Wegmans.) Interestingly, places associated with high quality (Citarella, Lobster Place, etc) do not appear. Also doesn’t look like they went to ethnic neighborhoods (no mention of Chinatown, etc) so it seems they targeted large chains.
