Who's regulating the Seafood Supply System?
The Chinese. 98% of the frozen fish in Kroger is from China. Farm raised (highly polluted) shrimp are from SE Asia and environs. I buy only wild caught shrimp from the gulf. If you saw the conditions of the environment where these shrimp are farmed you would toss your cookies.
My daughter has seen first hand the waters where the "wild caught" Chinese fish comes from. Horrifying.
If you think these chains are not serving Chinese caught fish, you are sorely mistaken.
I eat about a third of that.
