Colorado cantaloupes are the latest food to go under the microscope after the melons were linked to four deaths and 16 cases of Listeria, a potentially deadly bacterial infection.

While the FDA has not announced a recall on the fruit, the Centers for Disease Control and Prevention warned of the multi-state outbreak that health officials believe originated from the popular Rocky Ford cantaloupes, which are produced in the Arkansas Valley of Colorado. The cases were reported in five states: Colorado, Texas, Indiana, Nebraska and Oklahoma.
