A total of 212 laboratory-confirmed cases of Cyclospora infection have been linked to people who consumed pre-packaged Del Monte Fresh Produce vegetable trays containing broccoli, cauliflower, carrots and dill dip from four states, according to a report from the Centers for Disease Control and Prevention.

The C.D.C. in a July 5 update said the incidents were reported in Iowa, Michigan, Minnesota and Wisconsin, and were associated with vegetable trays sold at Kwik Trip and Kwik Star locations. Seven people have been hospitalized in connection with the outbreak, but no deaths have been reported, the C.D.C. said.

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. Cyclospora infects the small intestine and usually causes diarrhea. Other common symptoms include loss of appetite, weight loss, stomach cramps/pain, bloating, increased gas, nausea and fatigue. Vomiting, body aches, headache, fever and other flu-like symptoms may be noted.

On June 15, Del Monte Fresh Produce recalled 6-oz, 12-oz and 28-oz vegetable trays sold in clear, plastic clamshell containers. The company said the recalled products were distributed to the following stores: Kwik Trip, Kwik Star, Demond’s, Sentry, Potash, Meehan’s, Country Market, FoodMax Supermarket, and Peapod.

Del Monte has not commented on the outbreak.
