Tainted salads from McDonald’s are being blamed for 163 cases of illness in 10 states.

The USDA says the sickness is being caused by the Cyclospora parasite. Usually traced to imported produce, Cyclospora causes were virtually unknown before about 1990, but it has been on the rise across the U.S. ever since. McDonald’s traced the source to a lettuce supplier in Illinois and stopped selling salads at over 3,000 restaurants last week until a new supplier was found.

Most people who become ill due to the bacteria will recover without treatment. In more acute cases, the illness may last a few days to a month or longer. People who have weakened immune systems may be at risk for a more severe, prolonged illness.

Three of the people infected so far have been hospitalized.
