McDonald's Cyclospora Outbreak


The FDA and CDC announced an investigation into a Cyclospora outbreak linked to McDonald's locations in Iowa, Illinois, Kentucky, Minnesota, Missouri, Nebraska, Ohio, South Dakota, and Wisconsin. To date, there are 476 confirmed cases of cyclosporiasis across 15 states. 21 people were hospitalized. Sick people reported consuming salad products from the McDonald's locations. 

On August 1, the CDC reported that the FDA had linked the outbreak to romaine lettuce and carrot mix distributed to McDonald's by the Fresh Express processor in Steamwood, Illinois. 

The romaine lettuce was from the same lot that was positive for Cyclospora that was distributed in pre-made salads and wraps by Caito Foods LLC. On July 30, FSIS issued a public health alert about pre-made salads and wraps produced by Caito Foods LLC. The pre-made salads and wraps were produced between July 15 to July 18, 2018, with either a “Best By,” “Enjoy by,” Best if Sold By,” or “Sell By” date ranging from July 18 through July 23, 2018.

There is no evidence that this cluster is related to the Del Monte vegetable tray Cyclospora outbreak
