At least 13 people have died in the U.S. from listeria infections linked to cantaloupes grown in Colorado, making it the most deadly U.S. outbreak of food-borne infection since 1998, authorities said.

Seventy-two people in 18 states have become ill with listeriosis traced to contaminated cantaloupe, the Atlanta-based Centers for Disease Control and Prevention said today in a statement posted on its website.

The Food and Drug Administration on Sept. 14 warned consumers not to eat cantaloupes from Colorado’s Rocky Ford region shipped by Jensen Farms. The cantaloupes with the brand name Rocky Ford were distributed from July 29 to Sept. 10 in at least 17 states.
