The FDA, CDC, along with state and local officials are investigating a multi-state outbreak of cyclosporiasis illnesses likely linked to salads from McDonald’s restaurants.
The CDC reports that 163 people in 10 states have become ill. There have been 3 hospitalizations and no deaths.
As this is an ongoing investigation, the FDA will update this page as more information becomes available, such as product information, epidemiological results, and recalls.
The FDA is working with McDonald’s to identify the common ingredients in the salads identified by those who became sick and to trace back those ingredients through the supply chain.
As of July 13, 2018, McDonald’s has decided to voluntarily stop selling salads at impacted restaurants in IL, IA, IN, WI, MI, OH, MN, NE, SD, MT, ND, KY, WV, and MO until they are able to switch to another salad supplier. More information can be found in McDonald’s Statement.
Consumers who have symptoms of cyclosporiasis should contact their health care provider to report their symptoms and receive care. Most people infected with Cyclospora develop diarrhea, with frequent, sometimes explosive, bowel movements. 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. Some people who are infected with Cyclospora do not have any symptoms. 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 (relapse).
