Some illnesses have been reported from people eating veggie trays from Kwik Trip stores in Minnesota and Wisconsin.

Kiwk Trip has voluntarily pulled the items. Health officials say they issued a warning after investigating an increase of infections from Cyclospora, a parasite commonly found in developing countries. Officials say 11 people in Wisconsin and three in Minnesota reported buying vegetable trays at Kwik Trip prior to getting sick.

The Associated Press reported that officials say the Del Monte vegetable trays included broccoli, cauliflower, carrots and dill dip.

Health officials say it can take up to a week to develop symptoms, which can include diarrhea, loss of appetite, nausea, cramping, bloating, increased gas, fatigue and low-grade fever.

Kwik Trip owns more than 600 convenience stores in Wisconsin, Minnesota, and Iowa.
