There's all kinds of articles out now reporting this. Here is a random one from Google.
The FDA is allowing imported fish from China where the farms are using more economical food sources for tilapia, shrimp and other farmed fish. the foods include pig, cow and poultry feces. They are also constantly dosed with antibiotics.
I haven't eaten tilapia in some time and refuse to do so. Too easy to catch my own fish to eat and feed to my fishes.
With the FDA recently removing the requirement of informing consumers of country of origin when selling meats, you have no clue where your meat comes from. And IF they choose to label country of origin there is no regulation requiring them to do so. Thus, they can put whatever country on that label they want, whether it's the truth or not, likely without consequence.
Your fish Probably don't sense that the tilapia is full of crap ( literally) they Probably aren't used to the texture or taste. Just being picky. Either way, no one in my family, fish included, are eating that stuff anymore.
