There are approximately 30 cases of poisoning caused by Marine Toxins.


To best prevent poisoning:

  • Keep fresh tuna, mackerel, grouper, and mahi mahi refrigerated to prevent development of histamine. Don't believe that cooking spoiled or toxic seafood will keep you safe. These toxins are not destroyed by cooking.
  • Do not eat finfish or shellfish sold as bait.
  • Check with officials before eating local shellfish
