Rick Barrett of the Journal Sentinel reports that Wisconsin and Minnesota health officials are investigating an increase of Cyclospora infections that may be linked to Del Monte vegetable trays purchased from Kwik Trip stores.

Eleven people in Wisconsin and three in Minnesota have reported becoming ill after eating vegetables from the trays that contained broccoli, cauliflower, carrots and dill dip, according to the Wisconsin Department of Health Services.

Kwik Trip has removed the 6-ounce and 12-ounce trays from its stores and is cooperating with state officials. The trays may also have been available from other businesses, health officials said.
