Tuna mislabeling in LA sushi restaurants

Oceana’s 2013 and 2019 seafood fraud reports found that 33% to 87% of ‘tuna’ samples from US sushi restaurants were mislabeled ^[1][2]. Common substitutions include escolar (often sold as ‘white tuna’) and yellowfin tuna sold as bluefin tuna ^[1][2]. Escolar contains a waxy ester called gempylotoxin that cannot be digested, causing gastrointestinal issues such as diarrhea, oily stools, nausea, and cramping ^[1][2]. The provided sources do not list any Los Angeles omakase restaurants that explicitly disclose species and origin, so this question cannot be answered from the given materials. To answer, a list of LA omakase restaurants with their menu disclosure practices would be needed.
