2. Fish poisoning causes nausea, vomiting, diarrhea, abdominal pain, dizziness, and headache. Specific types of fish poisoning can cause other signs and symptoms, such as: Ciguatera (caused by toxins in some fish) Pufferfish poisoning Shellfish poisoning 3. Fish and shellfish contain poisonous biotoxins, even if well cooked. Certain fish--groupers, barracudas, moray eel, sturgeon, sea bass, red snapper, amberjack, mackerel, parrot fish, surgeonfish, and triggerfish--can cause ciguatera fish poisoning. 4. Reef fish from the tropical and subtropical waters of the West Indies, the Pacific Ocean, and the Indian Ocean pose the greatest threat. Cases have been reported in the United States in California, Hawaii, Texas, Guam, Puerto Rico, Vermont, U.S. Virgin Islands, and Florida, and a few isolated cases of ciguatera poisoning have even been noted along the eastern seaboard of the United States. 5. Symptoms may include: Nausea Vomiting Watery diarrhea Headache Numbness and tingling about the mouth and extremities In more severe cases, the person may suffer muscle pains, dizziness, and sensations of temperature reversal 6. Treatment for ciguatera poisoning involves relieving the symptoms and treating any complications 7. Tetrodotoxin, also called pufferfish poisoning or fugu poisoning, is a much rarer form of fish poisoning, but it is potentially very serious. 8. Symptoms generally appear between 20 minutes and three hours after eating the poisonous pufferfish Symptoms may include: Numbness of lips and tongue Numbness of face and extremities Sensations of lightness or floating Headache Nausea and vomiting Abdominal pain 9. Diarrhea Slurred speech Difficulty walking Extensive muscle weakness Convulsions Respiratory distress Mental impairment Cardiac arrhythmia Death can occur within four to six hours of poisoning, so it is essential to seek immediate medical attention. 10. Treatment for pufferfish poisoning consists of limiting the body's absorption of the toxin, relieving symptoms, and treating life-threatening complications. There is no known antidote for tetrodotoxin. 11. Scombrotoxin, also called scombroid poisoning or histamine poisoning, occurs after eating fish that contain high levels of histamine due to improper food handling. It remains one of the most common forms of fish poisoning in the U.S. and worldwide. These fish, which include mahi mahi (dolphin fish), albacore tuna, bluefin and yellowfin tuna, bluefish, mackerel, sardines, anchovy, herring, marlin, amberjack, and abalone, have high amounts of histidine. 12. As a result of inadequate refrigeration or preservation, bacteria convert the histidine to histamine, and this leads to scombroid poisoning. This form of fish poisoning occurs worldwide in temperate and tropical waters. 13. Symptoms generally appear within minutes to an hour after eating affected fish. They typically last three hours, but can last several days. The following are the most common symptoms of scombroid poisoning. 14. Tingling or burning sensations in the mouth Rash on the face and upper body Drop in blood pressure Throbbing headache Hives and itching of skin Nausea Vomiting Diarrhea 15. Treatment for scombroid poisoning is generally unnecessary. Symptoms usually resolve within 12 hours and scombroid poisoning is rarely life-threatening. Treatment could include antihistamines, such as diphenhydramine (Benadryl) and cimetidine (Tagamet). 16. keep the fish temperature controlled, and do not allow the fish to grow bacteria where the fish came from and how it was handled All cases should be reported to improve assessment on incidence Increase awareness of disease amongs fish handlers and consumers 17. Fish and shellfish poisonings occur on occasion in the United States. You can protect yourself by avoiding fish and seafood caught in and around the areas of a known red tide, and by avoiding clams, mussels, and oysters during the summer months. If you are poisoned, your long- term outcome is usually quite good. 18. http://www.nlm.nih.gov http://www.hopkinsmedicine.org http://www.cdc.com http://www.wikipedia.com http://www.google.mu http://www.nyc.gov http://umm.edu
