Preventive efforts include not eating reef fish, not eating high-risk fish such as barracuda, and not eating fish liver, roe, or fish heads. (wikipedia.org)
[ 1 ] It is caused by consumption of reef fish contaminated with ciguatoxin, which originates with certain dinoflagellates (ie, algae) associated with coral reef systems and accumulates up the food chain from small herbivorous fish to larger carnivorous fish, such as barracuda (see the image below) and grouper. (medscape.com)

Although the symptoms may resolve with basic treatment commonly used for an acute allergic reaction, they instead may have been caused by an excess amount of histamine in the fish, 4 known as scombroid poisoning. (medicalcases.eu)
As fish consumption has increased over the past three to four decades, so has the number of histamine fish poisonings. (medicalcases.eu)
The poisoning is the result of histamine in the flesh of the fish, and is usually self-limited and of short duration. (medicalcases.eu)
Reports of scombroid poisoning started in 1968, but histamine was not proven to be the culprit until 1991. (medicalcases.eu)
During scombroid poisoning, your body is not producing the histamine, but is rather poisoned by the amount of histamine in the flesh of the fish. (medicalcases.eu)
Bacteria normally inside of these fish, including Escherichia coli, Proteus, Klebsiella, Clostridium and Salmonella, contain an enzyme that converts histidine to histamine. (medicalcases.eu)
The bacteria are unable to convert histidine to histamine when the fish is kept at a temperature of 32 degrees Fahrenheit (0 degrees Celcius) or lower. (medicalcases.eu)
However, when the fish is stored at temperatures above 68 F (20 C), it only takes a few hours for enough histamine to be created to cause problems. (medicalcases.eu)
Histamine food poisoning from gram-negative bacteria in fin-fish products is also common, and Morganella morganii and M psychrotolerans are particularly strong histamine producers. (medscape.com)
