Health effects Escolar's wax ester content can cause keriorrhea (Greek: flow of wax), gempylotoxism or gempylid fish poisoning. Symptoms range from stomach cramps to rapid loose bowel movements, occurring 30 minutes to 36 hours following consumption. This condition may also be referred to as steatorrhea. Two known ways to reduce the likelihood of escolar-induced keriorrhea are to limit portions to six ounces (170 g) or less and to consume portions close to the tail, which typically have a lower wax ester content. Reports conflict on whether deep skinning, freezing or grilling will reduce the likelihood of keriorrhea.
