What Are The Symptoms Of Food Poisoning From Fish

There are two types of food poisoning you can get from eating fish. They are ciguatera poisoning and scombroid poisoning.

Ciguatera poisoning symptoms include abdominal cramps, nausea, vomiting, and diarrhea. Symptoms can progress to headache, muscle aches, and itchy, tingly, or numbness of the skin. One early sign can be numbness of the lips, tongue, or area around the mouth. You may have a metallic taste or feel like your teeth are loose. You may notice a change in your ability to feel hot or cold temperatures. You may think something feels hot when it is actually cold.

Scombroid poisoning symptoms develop 20 to 30 minutes after you eat the affected fish. They include flushing of the face, nausea, vomiting, hives, and abdominal pain. These symptoms are similar to other allergic reactions. Getting scombroid poisoning does not mean you are allergic to fish.

You can reduce your risk of exposure by not eating undercooked shellfish and other seafood. Wash kitchen utensils in hot, soapy water. Wear gloves when handling the fish if you have an open cut. Avoid ocean water until your cut or wound has healed.

Antibiotics are often used to treat the infection. In severe cases, you may need surgery or amputation where a cut or wound was infected with the bacteria.

Could Violent Vomiting Be A Shellfish Allergy

Dear Dr. Roach: I always thought that I had a cast iron stomach however, after a bout of suspected food poisoning about six months ago, I’ve had two incidences of violent vomiting for about a half hour. Both of the preceding two meals included shrimp, which I have eaten often in the past without a problem. The episodes were just a month apart. In trying to find an answer, I was surprised to read that shellfish allergy can develop suddenly in adults. I’m afraid to eat it again, and I’ll follow up with my doctor for an allergy test.

— M.C.W.

Dear M.C.W.: Allergies to fish and shellfish are common, seen in about 3% in U.S. adults. The symptoms vary among different people affected. Of all the shellfish, shrimp is likeliest to cause an allergy.

The usual allergic reaction to shrimp, called the IgE-mediated response, begins within minutes. The skin may show redness or warmth, itching or hives people may notice tingling or swelling in the mouth or lips and severe allergic reactions can cause dizziness, fainting, low blood pressure and confusion. It can sometimes lead to cardiac arrest. Severe allergic reactions can be extremely serious.

Finally, it’s possible that you have had bad luck and have had several episodes of diarrheic shellfish poisoning from contaminated shellfish.

An allergist is the ideal consultant to help sort out whether this really is an allergy. Both blood tests and skin tests may be helpful. I agree with you avoiding shellfish until you get evaluated.

Clinical Presentations Of Shellfish Allergy

Symptoms may be limited to transient oral itching or burning sensation within minutes of eating shellfish . Recently, a case of food protein-induced enterocolitis syndrome to shellfish has been reported in a 6-year-old boy after ingestion of clam . Food-dependent exercise-induced anaphylaxis has also been described to shellfish . In certain subjects, anaphylaxis may result by a synergistic effect of nonsteroidal anti-inflammatory drugs with shellfish intake .

Shellfish protein is a potent allergen and can provoke symptoms by inhalation or skin contact . Airborne allergens are particularly abundant in the vicinity of cooking shellfish by boiling, steaming, or frying. Occupational exposure, such as in snow crab processing plants, not only can cause symptoms in highly allergic subjects, but can also cause de novo sensitization . Symptoms may be limited to the respiratory tract or affect other systems such as the skin or systemic anaphylaxis.

When To See A Doctor

Contact a doctor if you have diarrhea that lasts for more than three days or you experience any of the following:

  • Prolonged vomiting that makes you unable to keep liquids down.
  • Bloody diarrhea
  • A fever higher than 101.5° F.
  • Dehydration symptoms, such as decreased urination, a dry mouth and throat, and overwhelming thirst, or dizziness when you’re standing up.

Your doctor will probably order stool and blood tests to pinpoint the cause. If it turns out that you have listeria or foodborne salmonella that has spread to the bloodstream, he or she will prescribe an antibiotic. The primary treatment is likely to be intravenous fluids to fight dehydration. In severe cases you may need to be hospitalized.

Some people are more vulnerable to foodborne infections than others and get sicker from them. For them, it might be a good idea to err on the side of caution by contacting a doctor when the first symptoms appear rather than waiting for those red flags.

Young children and elderly people who are sickened by shiga-toxin-producing E. coli, such as O157:H7, are at higher risk of developing a complication called hemolytic uremic syndrome, or HUS, which can cause life-threatening kidney damage, for instance. Others in higher-risk groups include pregnant women and infants, as well as anyone who has underlying bowel disease such as ulcerative colitis or whose immune system is weakened by illness or treatments such as chemotherapy or long-term high-dose steroids.

What Is The Treatment For Shellfish Poisoning

There is no specific treatment for shellfish poisoning. However, some health care professionals may induce vomiting or use a stomach pump to remove food if the patient is seen within three hours of ingesting the shellfish.

These actions may reduce the amount of poison that is absorbed through the gastrointestinal tract. In addition, patients are often given IV fluids as they may become dehydrated from vomiting.

The use of oral charcoal may be used in some patients that are seen early after ingestion of large amounts of food likely containing large amounts of shellfish poison. Some health care professionals advise the stomach should be pumped to remove foods before charcoal is administered.

How A Neurotoxin In Crabs Causes Brain Damage

High levels of domoic acid in Dungeness and rock crabs has led to a fishing ban by the California Fish and Game Commission

The California Fish and Game Commission has banned crab fishing until further notice after detecting high levels of a neurotoxin in Dungeness and rock crabs. The toxin, domoic acid, is produced by certain types of planktonic algae, and it becomes concentrated in tissue of crabs and other marine organisms during plankton blooms. People who consume sufficient quantities of the toxin develop amnesic shellfish poisoning, so named because it kills neurons in a part of the brain that is critical for memory. Heres how it works

To most of us it comes as a surprise that crabs can be toxic, but we are all familiar with the rule that oysters should not be eaten except in months that contain the letter R. The mnemonic is a clever way to remember not to eat wild oysters and other shellfish during summer months, because the warm water fuels blooms of phytoplankton that contain toxins. Since the toxins are not broken down readily or rapidly eliminated from the body, they become concentrated in tissue as the shellfish filter feed on microorganisms suspended in the water.
