What fish gives you diarrhea after eating?

Answered by Antonio Sutton

Consuming escolar and oilfish can lead to a specific type of food poisoning known as keriorrhoea, which is characterized by oily diarrhoea. These fish are known for their high oil content, which can have a laxative effect on the human digestive system.

Escolar, also known as white tuna or butterfish, is a deep-sea fish that contains a naturally occurring wax ester called gempylotoxin. This compound is not easily digested by the human body and can cause gastrointestinal symptoms such as diarrhoea, abdominal cramps, and nausea when consumed in large quantities. The oily nature of escolar’s flesh is often considered to be the cause of keriorrhoea.

Similarly, oilfish, also known as snake mackerel or butterfish, contains a high amount of wax esters, particularly gempylotoxin. When consumed, these compounds can have a similar laxative effect on the digestive system, leading to oily diarrhoea.

It is important for both consumers and food businesses to be aware of the risks associated with consuming escolar and oilfish. While these fish may be marketed as a delicacy due to their rich flavor and texture, their high oil content can cause unpleasant gastrointestinal symptoms.

Consumers should exercise caution when consuming escolar and oilfish, especially in large quantities. It is recommended to consume these fish in moderation and be aware of the potential side effects. If symptoms such as oily diarrhoea occur after consuming these fish, it is advisable to seek medical attention.

Food businesses should also be mindful of the risks associated with serving escolar and oilfish. Proper labeling and disclosure of the potential side effects should be implemented to inform consumers about the possible gastrointestinal effects. Additionally, food establishments should ensure that these fish are sourced from reputable suppliers and handled and cooked properly to minimize the risk of food poisoning outbreaks.
