Meanwhile, 15 people in four states have become infected with Listeria from eating cantaloupes from the Rocky Ford region of Colorado.  Other infected persons include "11 people in Colorado, two in Texas, and one person each in Nebraska and Okalahoma," according to CNN.com.  Listeria can cause listeriosis, which can is uncommon, but can be fatal.
