Bagged salad mix is the apparent cause of an intestinal parasite outbreak that has sickened more than 370 people in 16 states, including one case in Minnesota.
"The evidence points to a salad mix containing iceberg and romaine lettuce, as well as carrots and red cabbage as the source of the outbreak reported in Iowa and Nebraska," said Steven Mandernach, chief of the Food and Consumer Safety Bureau of the Iowa Department of Inspections and Appeals.
Two cases of cyclosporiasis were reported in Iowa on June 28. The illness is caused by an intestinal parasite that comes from contaminated food or water.
Iowa health officials didn't specify a brand or source of the bagged salad, but said it is no longer in the food supply chain.
The time between becoming infected with cyclosporiasis and becoming sick is usually about one week. Cyclospora usually causes watery diarrhea, with frequent and sometimes explosive episodes.
Other common symptoms include loss of appetite, weight loss, stomach cramps, bloating, increased gas, nausea and fatigue. Vomiting, body aches, headache, fever and other flu-like symptoms may be noted.
If not treated, the illness may last from a few days to a month or longer. Symptoms may seem to go away and then return one or more times Some people who are infected with Cyclospora do not have any symptoms.
