The gastrointestinal symptoms, called "keriorrhoea", caused by these wax esters may include oily orange diarrhea, discharge, or leakage from the rectum that may smell of mineral oil. The discharge can stain clothing and occur without warning 30 minutes to 36 hours after consuming the fish. The oil may pool in the rectum and cause frequent urges for bowel movements due to its lubricant qualities and may be accidentally discharged by the passing of gas. Symptoms may occur over a period of one or more days. Other symptoms may include stomach cramps, loose bowel movements, diarrhea, headaches, nausea, and vomiting.

Reminds me of Olestra...
From Wiki as well.

Olestra was approved by the Food and Drug Administration for use as a food additive in 1996 and was initially used in potato chips under the WOW brand by Frito Lay. In 1998, which was the first year Olestra products were marketed nationally after the FDA’s Food Advisory Committee confirmed a judgment it made 2 years earlier, sales were over $400 million.[5] However, by 2000 sales slowed to $200 million, largely caused by the unappealing side effects described on the FDA-mandated health warning label:

This Product Contains Olestra. Olestra may cause abdominal cramping and loose stools. Olestra inhibits the absorption of some vitamins and other nutrients. Vitamins A, D, E, and K have been added.

This condition (normally occurring only by excessive consumption in a short period of time) became popularly known as "anal leakage." Sales were so slow that P&G gave up on attempts to widen the uses of Olestra, and even sold off their Cincinnati-based Olestra factory to Twin Rivers Technologies in February 2002.[4]
