1. Imported Catfish
Catfish can grow to a relatively large size. Unfortunately, many fish farmers feed them hormones to accelerate their growth, particularly the imported fish that comes from Asian countries. This puts the health of all consumers in danger, leading to countless new health problems.
When buying this kind of seafood, you should opt for free-grown catfish, as they have greater nutritional value and are much less dangerous. Otherwise, just avoid it altogether.
