Huffington Post -Oceana, an international ocean advocacy group, has released a report on national seafood fraud, and the results are disconcerting. The report, which is one of the largest on seafood fraud to date, found that one-third of fish was mislabeled.
Oceana performed DNA testing from 2010 to 2012 on 1,215 fish samples
from 674 retail outlets in 21 states. In this study, Oceana found
seafood fraud everywhere it tested, with rates hitting as high as 52
percent in Southern California.
