Cases of people infected by the Cyclospora parasite, believed to have originated from ingesting lettuce in McDonald’s salads, have spread to another four states—Wisconsin, Nebraska, South Dakota, and Minnesota.
The numbers are limited so far, according to health officials, who say each state has two cases, with the exception of Minnesota, which has three, reported USA Today.
The Iowa and Illinois health departments said on Thursday that they were investigating Cyclospora infections linked to salads at McDonald’s restaurants. The Illinois Department of Public Health said it had recorded about 90 cases since mid-May, and the Iowa Department of Public Health said it had recorded 15 cases since late June.
