Fish poisoning can occur in two ways: ciguatera poisoning from ingested toxins in tropical fish, and scombroid poisoning from improperly cooked fish. Pufferfish can cause serious poisoning, including paralysis and death, even if cooked thoroughly. Symptoms vary but may include abdominal pain, nausea, and muscle weakness. Immediate medical attention is necessary for pufferfish poisoning.
Fish poisoning in humans can be a serious medical problem. There are two basic types of fish poisoning, known as ciguatera poisoning and scombroid poisoning. Ciguatera poisoning occurs when a person eats a fish that has ingested a type of toxin. Scombroid poisoning can occur when a person eats fish that hasn’t been cooked properly. A particular type of fish, known as pufferfish, can cause more serious poisoning problems and requires immediate medical attention.
Ciguatera fish poisoning is possible when someone eats a reef fish or fish from tropical areas that has ingested some sort of harmful toxin. These toxins remain in the fish even after the fish has been frozen or cooked. This type of fish poisoning is not fatal and goes away on its own after a period of time.
Symptoms of ciguatera poisoning typically include abdominal pain or cramping. These symptoms may be accompanied by varying degrees of nausea, vomiting or diarrhea. Muscle aches or headaches may also be present. Some people may experience numbness, tingling, or itchy skin.
Scombroid fish poisoning can occur from eating raw fish or fish that hasn’t been cooked properly or thoroughly. If a fish is allowed to get too warm after being caught, a substance known as histamine could build up inside the fish. If this fish is then improperly prepared for human consumption, a person’s immune system can react negatively to this histamine buildup, leading to an allergic type of reaction.
Symptoms of mackerel poisoning usually occur within minutes of eating the fish and can include abdominal pain, nausea, or vomiting. Facial flushing or a sudden onset of rash or hives may also occur. It is important to note that this type of poisoning does not automatically mean that the infected person is allergic to all fish. An over-the-counter antihistamine is often all that is needed to treat this type of reaction, although it is generally advisable to visit a doctor for a clear and accurate diagnosis.
Pufferfish are a type of poisonous fish that some people around the world choose to eat despite the risks. The poison found in this fish can sometimes remain in the meat even after thorough cooking. This type of fish poisoning can cause permanent paralysis or even death and should be treated as a medical emergency. Early symptoms often include facial numbness, slurred speech, and muscle weakness.
