Oceana, a nonprofit ocean conservation organization, tested seafood sold at U.S. restaurants and retailers and found that roughly 1 in 5 samples was mislabeled. In some species categories — snapper, tuna, grouper — the mislabeling rate exceeded 50%.
This is not primarily a fraud problem at the retail level. It is a traceability problem throughout the chain. When dozens of vessels' catch is commingled at a tender, and then reprocessed and relabeled at a facility handling multiple species, the conditions for substitution are structural.
The solution is not better labeling regulation — though that would help. The solution is shorter chains where accountability is undivided and substitution has nowhere to hide.
