Dole Whip® samples from both the Tiki Bar Lounge in Disneyland and the original manufacturer, Dole®, were tested in a 90-day long toxicological study to test the effects each sample would have on Mickeylius myceus, the model organism for this experiment. Those within the Disneyland group that were treated with Dole Whip™ were diagnosed with lymphoma, which was caused by aspartame, an artificial sweetener.
