Precautions for amberjacks, barracudas, snapper, grouper, and other carnivorous tropical fish:

Ciguatoxin

Carnivorous tropical fish may eat smaller fish that have eaten algae carrying ciguatoxin. Ciguatoxin is a natural toxin produced by microscopic plants living in tropical waters. Ciguatera is a disease caused by eating the fish, which have accumulated levels of ciguatoxin. Larger fish can be thusly more toxic, from eating more fish that have this toxin. Ciguatoxin is not destroyed by cooking. Mussels, clams and oysters are also susceptible. Avoid eating viscera including liver, intestines and roe of all tropical fish.

Symptoms include:

  • vomiting
  • itching
  • nausea
  • dizziness
  • hot/cold flashes
  • temporary blindness
  • hallucinations
  • other central nervous system dysfunction

Remember these are only guidelines or basic information. Contact your local extension service for more detailed information or the latest recommendations, or a seafood governmental agency.
