Instead of butterfish consumers have been eating escolar an oily fish that can cause diarrhea, hence known as “diarrhea of the sea”.
Halibut sold as haddock and wild salmon sold as farmed Atlantic salmon
Mislabeling was highest in restaurants and fish prices were much higher than what was actually sold.

But fraud rates have dropped due to these tracking policies.
