UNDATED (WSAU) State health officials say they have not found a link yet between two Wisconsinites who got listeria, and the cantaloupe that caused at least 13 deaths around the country. The U-S Centers for Disease Control said two Badger State residents were among at least 72 people infected with the same listeria that was linked to the Colorado cantaloupe.

Stephanie Smiley of the state health services agency said the two patients were elderly people from Milwaukee and Racine counties. And both were treated at hospitals and later released.

Officials said people in 18 states suffered illnesses traced to Rocky Ford cantaloupes grown in Granada Colorado. It’s the nation’s largest food-borne disease outbreak in over a decade.

The C-D-C and the Food-and-Drug Administration could not say where all the tainted melons went, because they were sold and re-sold to many distributors throughout the country.

Officials said listeria is deadlier than more common food bacteria like salmonella and E-coli. Listeria generally hits the elderly, pregnant women, and those with weakened immune systems.
