Although fish that is unsafe to eat sometimes announces itself with an unpleasantly fishy, ammonia-heavy aroma and limp appearance, some harmful species containing dangerous toxins can appear perfectly fresh and appetizing.
Ciguatera poisoning is the scourge of tropical waters in the Caribbean, Florida and even Hawaii. Numerous species of dark-meat fish, such as tuna, mackerel and mahi mahi, start to produce histamine in significant quantities once the fish dies.
The most fearsome form of food poisoning from fish comes from the puffer fish, also known as the fugu or blowfish in Japan, where it is a delicacy. Fish poisoning has recently been brought to attention by the media, in particular, scombroid poisoning. It is important to note that cooking the fish thoroughly will not destroy the histamine toxin. Scombroid fish poisoning is often missed because it resembles an allergic reaction. The symptoms of poisoning can show within just minutes of eating the spoiled fish.
H1 and H2 receptor (histamine receptors) blocking medications can also be given with some success. The symptoms can be extremely uncomfortable but generally are not fatal and resolve within 12 hours [1]. To prevent contamination, fish must be adequately chilled, immediately after catching – this will inhibit the production of histamine.

Knowledge of a fish’s origin, and proper storage and serving, are the best guarantees against a dose of food poisoning. The poisoning comes from a toxin produced by algae on coral reefs, which then travels up the food chain until it is concentrated at dangerously high levels in around 400 species of larger predatory fish, such as barracuda, jack, grouper and snapper. The risk of poisoning is most elevated in catch that has been exposed to air or water temperatures above 83 degrees Fahrenheit.
Symptoms usually appear within 12 hours and include muscle weakness, blurred vision and, at worst, breathing failure. The fish contains a lethal tetrodotoxin in the liver and skin that first causes numbness or tingling around the mouth, but soon leads to twitching, paralysis and suffocation, with death coming in as little as 20 minutes.
It is still uncertain whether the case in question was caused by scombroid poisoning, none the less, it is good to raise awareness of the importance of food safety to avoid any serious consequences. These fish contain the chemical histadine and when incorrectly stored, bacteria within the fish breakdown the histadine into histamine. Physical signs may include a diffuse blanching erythema, tachycardia, wheezing and hypotension or hypertension. The fish should be promptly submerged in ice, refrigerated or frozen and kept below 5°C until cooked.

In particular, Belinda has a broad range of experience with weight management, diabetes, oncology, high cholesterol, malnutrition, childhood nutrition and gastrointestinal disorders. Transmitting fish display no visible signs, and cooking or freezing does not destroy the toxin, which is concentrated in the fish’s liver and kidneys.
As a result, puffer fish must be prepared by a specially licensed chef in Japan and is banned in the U.S. Some potential signs of contamination may be expressed as a bubbly, salty or sharp feel of the fish [2].


However, the Centers for Disease Control and Prevention (CDC) have largely associated poisoning with non-scombroid fish as well e.g.
People with asthma are more vulnerable to respiratory problems such as wheezing or bronchospasm.
Passionate about health and wellbeing, we write about issues relevant to our clinical practice.
Symptoms appear as early as two hours after having eaten a ciguatera-infected fish, but typically take 12 to develop.
The danger with scombroid food poisoning, which is also referred to as histamine poisoning, is that the bacteria are heat-stable, so cooking will not eliminate the danger.
Spread by poor sanitation practices, the bacteria can survive in salt or fresh water, and cause cramps, fever and vomiting within four hours, with the danger particularly elevated for infants, the elderly and those with a weakened immune system.
In Florida, however, several native species of puffer fish that feed on toxic algae can cause poisoning in cases where the fish is mistaken for a safer species. We’ve never had ciguatera (cross our fingers) and tend to avoid any fresh fish caught in reef areas.
At first, the poisoning resembles conventional food poisoning with cramps, vomiting and diarrhea, but ciguatera is the likely culprit once the victim complains of confusion between hot and cold temperatures, a metallic taste and the feeling that the teeth are falling out. Symptoms occur very quickly after eating the fish, but do not usually last longer than 24 hours. Most harmful bacteria on fish grow quickly at temperatures above 40 F, so fish should be refrigerated immediately before and after cooking. The FDA also warns that some species of fish can contain trace elements of mercury, a possible risk to pregnant women, who should avoid shark, swordfish and king mackerel accordingly. With that in mind though, a cruising friend bought some fresh fish at a market in Vanuatu and was deathly ill with it. Telltale signs include hives, red skin on the face and body, flushes, nausea, vomiting and difficulty breathing.
Cooking to at least 145 F, or up to 165 for stuffed fish, will also neutralize bacteria, but not toxins.
Luckily, our good friend and naturopathic physician, Alan Profke, was in the anchorage at the time and was able to treat Isolde and help her recuperate.
Poisoning does not usually last for longer than a few hours, but could lead to hospital treatment in the elderly or those with low immune systems. Bacteria also spread easily when cross-contamination between raw and cooked fish and meats is allowed to occur, and pregnant women are advised against eating refrigerated smoked fish, such as salmon, whitefish and mackerel pates. Captain James Cook himself suffered with this malady twice whilst in the New Hebrides, or Vanuatu as it is now known. The toxins that produce ciguatera come from a group of organisms called dinoflagellates that proliferate in tropical and subtropical waters. Dinoflagellates adhere to coral, algae, and seaweed where they are eaten by herbivorous fish who are in turn eaten by larger fish and so on.
Gamberdiscus toxicus is the primary dinoflagellate responsible for the production of a number of toxins that bring on ciguatera. Ciguatera is odourless, tasteless and heat resistant, so the toxin cannot be eliminated by cooking.Which fish carry ciguatera?The fish that affected Captain Cook was thought to be a red bass, however there are many fish that carry the toxins.
In fact, up to 400 species of reef fish have been identified so far that are affected by these toxins.
The fish that are most likely to be affected are RED BASS, WRASSE, TRIGGER FISH, SNAPPER, SPANISH MACKEREL, QUEEN FISH, MORAY EELS, CORAL TROUT, BARRACUDAS, PARROT FISH,GROUPERS, AND AMBERJACK. The symptoms can last for weeks, or in more severe cases, can take months or even years to finally be gone. In some cases, the poisoning has led to long term disability, but this is not generally the norm. Many patients that have had severe cases of fish poisoning have told me of repeated symptoms months or years later after eating fish, even when the fish has not affected anyone else who has eaten it. It has been reported that symptoms can also be triggered by nuts, seeds, alcohol, products containing fish, chicken, eggs and even exposure to bleach and other chemicals.
This, I have only found in the worst cases.The major symptoms in humans are gastrointestinal and neurological.


Nausea, vomiting, cramping in the abdomen, metallic taste, aching teeth, and diarrhea are often followed by neurological symptoms, such as headaches, myalgia (muscle aches), paraesthesia, numbness, vertigo, hallucinations and ataxia. Excessive sweating may be the first sign, however tingling or altered sensation around the lips, mouth, tongue and throat are the most common first signs. There may be numbness, tingling or extreme sensitivity or even reversed feelings of heat and cold.
It has been reported that healthy partners of a ciguatera-affected person can suffer some of the symptoms after sexual intercourse, signifying that the toxin may be transmitted sexually as well. Facial rashes and diarrhea have been reported in infants being breastfed when the mother has been poisoned, so this may be another route for secondary poisoning. In the most severe cases, breathing can be affected, so the person who is affected needs to be monitored closely.How do I know if a fish is poisoned?First of all, when you are near an island check with the locals.
They may point out certain areas that are affected, so the advice is steer clear of fishing in that area or even close to it.There have been many suggestions made and theories put forth as to how one can tell if a fish is affected or not. I will list some of these here, but must stress that none of these is scientifically validated.Take a tiny piece of the raw fish flesh and hold it in your mouth, preferably under your tongue. If you perceive any numbness or a tingling sensation, then ditch the fish.If you have any tingling, numbness or a stinging sensation on your hands or skin whilst filleting the fish, ditch it. This one I know personally is incorrect having lost my dearly loved moggie on a trip to the Great Barrier Reef.
The toxin affected him within two hours and despite our most heroic efforts to save him, he died shortly thereafter. He had eaten part of the liver of a mackerel that I had filleted.Try putting a piece of fish on the ground to see if the ants will touch it. If ants continue to walk on the fish and not die, then it is considered safe.None of these methods has any scientific validity, so I would not place a lot of faith in any of them.
I personally use the sub-lingual method and to date have not suffered any effects of ciguatera. It is vitally important that the affected person be resting and drink absolutely no alcohol. I personally use a product from the USA called Trenev Trio or Healthy Trinity (Natren is the company in the US).
In the first stages, take one capsule before morning and evening meals and, as you improve, reduce to one capsule only before the evening meal.Liver support is vitally important, so in this regard, I use a homeopathic medication from a company called Heel (Germany). This is very effective for treating the nausea and assisting both phase 1 and 2 in detoxifying of these toxins.To treat the diarrhea, I use Saccharomyces Boulardi. This is available in 250 mg capsules and can be used in the acute phase at two capsules, three times per day.
Again, as you improve, lessen the dose to one capsule three times per day and then down to one capsule twice per day until totally recovered.Calcium channel blocker drugs have been used to reduce the severity of the symptoms of ciguatera. It is imperative that the magnesium is either a citrate or a diglycinate, so as not to exacerbate the diarrhea. In the case of the homeopathic medicines recommended, you can break the tablet into two.A drug called Questran has also been used to assist in ridding the body of ciguatera toxins.
This drug combines with bile acids and prevents them being reabsorbed, thereby excreting the toxin through the bowel movement. A good liver support that assists phase one and two detoxification is vital along with the probiotics that assist bowel detoxification. To that end, I always suggest a least a good daily multi-vitamin that contains high doses of Vitamin B along with a good probiotic and a healthy diet.Many cruising yachties do ocean passages and suffer sleep deprivation and, in some cases, dehydration .
To assist the body in its recovery and to support good health, the minimum I would suggest would be the good multi-vitamin and a probiotic. In my clinic in Australia, I seldom see ciguatera, but I often see it in Vanuatu where I also have a clinic. I have had very good results using the above to assist the many native patients I see on our island home and some of the cruisers who visit us from time to time.
