Federal health officials on August 2 confirmed an additional 109 cases of cyclospora infection involved in an ongoing outbreak linked to McDonald's salads, according to CNN.
The total number of laboratory-confirmed cases of cyclosporiasis from the outbreak, which started in May, is now 395, according to an August 2 update from the FDA. At least 16 people have been hospitalized.
So far, illnesses have been reported across 15 states: Connecticut, Florida, Iowa, Illinois, Indiana, Kentucky, Michigan, Minnesota, Montana, Nebraska, Ohio, South Dakota, Tennessee, Virginia and Wisconsin.
The FDA tested an unused package of Fresh Express salad mix distributed to McDonald's and confirmed the presence of Cyclospora, although the lettuce was tested past its expiration date.
"Epidemiologic evidence indicates that salads purchased from McDonald's restaurants are one likely source of these infections. The investigation is ongoing, and FDA is working to determine the sources of the ingredients that were in common to the salads served at McDonald's," the CDC said in an August 3 outbreak update.
Fresh Express recalled the salad mix July 27, and McDonald's swapped out the product for lettuce from a different supplier.
