TOPEKA, Kan. (AP) – Kansas health officials say two additional cases of listeria have been linked to tainted cantaloupes from Colorado, bringing the total to seven.

The Kansas Department of Health and Environment said Tuesday the seven cases include two resulting in deaths. The agency did not say when or where the cases occurred.

The federal Centers for Disease Control and Prevention reports 100 confirmed illnesses and 18 deaths nationwide linked to bacteria in cantaloupes from a single Colorado farm.

Symptoms of a listeria infection include fever, muscle aches, diarrhea and vomiting and can show up two months after the tainted fruit has been consumed.
