Scombrotoxic

 

Scombrotoxic food poisoning usually results from improper food handling or storage. While most often associated with fish (tuna and mackerel), any food (such as certain cheeses) that contains the appropriate amino acids and is subjected to certain bacterial contamination and growth may lead to scombroid poisoning when ingested. 

 
 
Reservoir
Fish, certain cheeses
 
 
Incubation period
10 mins - 2 hours.
 
 
Signs and Symptoms

Diagnosis
Diagnosis is usually based on a person showing the characteristic symptoms and is confirmed by detection of histamine in epidemiologically implicated fish.

Symptoms usually resolve spontaneously. In severe cases, antihistamines may be effective in relieving symptoms.
