Scombroid food poisoning, also known as simply scombroid, is a

irregular heartbeat may occur.[2][5]

Scombroid occurs from eating fish high in

bacterial growth occurs during improper storage.[2] Subsequent cooking, smoking, or freezing does not eliminate the histamine.[2] Diagnosis is typically based on the symptoms and may be supported by a normal blood tryptase.[2][1] If a number of people who eat the same fish develop symptoms, the diagnosis is more likely.[2]

Prevention is by refrigerating or freezing fish right after it is caught.

tropical waters.[2] Only one death has been reported.[3] The condition was first described in 1799.[1]

Signs and symptoms

Symptoms typically occur within 10–30 minutes of ingesting the fish and generally are self-limited. People with

wheezing or bronchospasms
. However, symptoms may show over two hours after eating a spoiled dish. They usually last for about 10 to 14 hours, and rarely exceed one to two days.

Initial

The first signs of poisoning suggest an allergic reaction with these symptoms:

  • facial flushing/sweating
  • burning-peppery taste sensations in the mouth and throat
  • dizziness
  • nausea
  • headache
  • tachycardia
  • cold-like symptoms

Additional symptoms

The above symptoms can advance to:

  • facial rash (intense itching may accompany the rash)
  • torso or body rash: The rash associated with scombroid poisoning is a form of
    urticaria, but most commonly does not include wheals (patchy areas of skin-swelling also known as hives) that may be seen in true allergies.[7]
  • edema (generalized if it occurs at all)
  • short-term diarrhea
  • abdominal
    cramps

Severe

In the worst cases, the poisoning may cause:

  • blurred vision
  • respiratory distress
  • swelling of the tongue

In rare cases, the poisoning may result in death.

Causes

Unlike many types of food poisoning, scombroid form is not brought about by ingestion of a

symbiotic bacteria such as Morganella morganii (this is one reason why fish should be stored in the freezer). Histamine is not destroyed by normal cooking temperatures, so even properly cooked fish can still result in poisoning.[9] Histamine is the main natural chemical responsible for true allergic reactions, so the symptoms produced are almost identical to a food allergy.[10][11] Rarely, cheese may be involved.[3]

Diagnosis

Differentiating scombroid from a fish allergy can be difficult, as both present with similar symptoms.[1] In scombroid, blood tryptase is generally normal, while in an allergic reaction, it is elevated.[1]

Prevention

Cooking, smoking, canning, or freezing will not destroy histamine in contaminated fish.[2] Antihistamines may also be taken before eating seafood.[3]

Treatment

Treatment is in the form of supportive care. If light-headedness occurs, a person should lie with feet partly elevated.

Epinephrine combined with a steroid may be used for severe symptoms.[3]

Epidemiology

Isolated reports of scombroid food poisoning in humans caused by histamine present in the tissues of stale or rotten scombroid fish, usually tuna, have occurred over the years. In September 2016, authorities in Singapore intercepted canned tuna imported from Thailand after finding high levels of histamine.

Guangdong province in China.[13] In August 2013, 26 people in Shenzhen were poisoned after eating stale mackerel. Several people became ill after eating tuna sandwiches at a cafe in Edinburgh in Scotland in 2013.[14] The tuna had come from Ghana. In 2011, 20 reports of food poisoning at a Stockholm restaurant were thought to be histamine poisoning in tuna from Senegal. In 2012, UK environmental health authorities in north east Lincolnshire intercepted and destroyed a shipment of tuna from Vietnam after four crew members were reported to have developed symptoms of histamine poisoning.[15] Commercially canned tuna was determined to be the cause of the poisoning of 232 persons in the north-central United States in 1973.[16]

History

The syndrome is named after the fish family Scombridae, which includes mackerels, tunas, and bonitos, because early descriptions of the illness noted an association with those species, although nonscombroid fish such as mahi-mahi and amberjack may also cause the condition.[citation needed]
