On July 4, 1850, President Zachary Taylor was diagnosed by his physicians with cholera morbus, a term that included diarrhea and dysentery but not true cholera. Cholera, typhoid fever, and food poisoning have all been indicated as the source of the president’s ultimately fatal gastroenteritis. More specifically, a hasty snack of iced milk, cold cherries and pickled cugreat timesbers consumed at an Independence Day celebration might have been the culprit.
