There have been a lot of articles written about the recent Oceana study that claims that more than 30% of the fish in South Florida is mislabeled. I had a problem with the study because they wouldn't disclose the venues or the distribution of the results. The questions such is "is every restaurant doing it"? or "Can I trust the fish in the supermarket"? couldn't be answered, and those are the answers we want.
I investigated a bit, and I found that there is a voluntary random testing program that tests fish, and that most of the major centers in our area are members. Sysco is also a member of the voluntary testing lineup. So I concluded that it's not really that big a problem generally; it's probably just unsavory restaurant owners who are trying to rip people off. Such behavior is almost expected at "some" places.
Florida's records are all available to the public, so I compiled lists of all of the restaurants that have been caught by State inspectors selling food that is not what the restaurant is claiming.
