6. Parasitic cysts in your bluefish or freshwater herring.
If “20% of the fish examined are infested” with parasitic cysts per 100 lbs of fish, then they are considered unsafe and will be discarded.
Parasites can infest your body upon entering through contaminated fish. They then continue to populate until you kill and expel them.
If you have eaten your fair share of fish over the years, it may be a good idea to do a parasite cleanse.
