What is a common symptom of Scombroid poisoning?

Scombroid poisoning is primarily caused by the consumption of fish that contains high levels of histamine due to improper handling or storage. When certain types of fish, such as tuna or mackerel, are not refrigerated adequately, bacteria can convert the naturally occurring amino acid histidine in the fish into histamine. The symptoms of scombroid poisoning are a result of a histamine reaction in the body, which can lead to flushing, sweating, headache, and gastrointestinal symptoms.

The correct choice reflects this connection to histamine and the nature of the poisoning. Individuals experiencing scombroid poisoning typically present with symptoms that are directly related to the histamine response, thus making a histamine reaction the most characteristic symptom associated with this type of food poisoning. Understanding this link is vital for food safety practices and recognizing the signs of foodborne illness related to fish consumption.
