December 7, 2018 — The 2018 Oceana Canada study was only the most recent of a series of similar studies published by Oceana (see my earlier piece here). In 2016, Oceana released a report that summarized and mapped seafood fraud from, “more than 200 published studies covering 55 different countries, on every continent except Antarctica, in order to reveal the global scope of seafood fraud.” Oceana found relevant studies by searching Google Scholar and Google News with relevant search terms. Further, legal cases involving seafood fraud in the United States were collected in NOAA Law Enforcement or Department of Justice press releases and archives. The final collection was displayed on this map.
In this post, I will attempt to contextualize Oceana’s findings in the US specifically. I aim to challenge the report title that this map study “reveal[ed] the global scale of seafood swapping”, and instead suggest that it provided an unrepresentative view of mislabeling in the context of actual seafood consumption trends in the U.S.
The vast majority of the studies collected by Oceana (>75%) were from Europe or the US and, “the bulk of the studies [were] conducted after 2005.” Globally, Oceana reported the weighted average mislabeling rate was 19%, but in the U.S., it was 28%. The most commonly mislabeled species in the US studies referenced were snapper, grouper, and salmon. Across all studies referenced (US and abroad) Oceana reported mislabeling in “all 200+ studies reviewed except one.”
Pins were placed on the world map to indicate the location of each mislabeling study collected for this report. The pins were color coded to indicate the extent of mislabeling, and to indicate if the study was an Oceana study or a study from another source like news media or peer reviewed literature. Dark red indicated studies showing mislabeling rates from 75%-100%; lighter red indicated mislabeling rates from 50%-75%; dark pink indicated rates from 25%-50%; light pink indicated rates from 0%-25%; a white pin with black pinstripes indicated a study featuring “other examples of fraud”; and a blue Oceana logo pin indicated an Oceana study.
