The symptoms that United States President Zachary Taylor began showing five days before his death are consistent with arsenic poisoning  Recent examination of Taylor' s bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor' s contemporaries
These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal dose of the poison
Taylor's death was not the result of any kind of poisoning.
