Over a dozen Michigan stores, including a Kroger and Whole Foods Market around Ann Arbor, Midland, Birch Run, and Saline, are believed to have suffered attacks by a man who sprayed a mixture of hand cleaner and rat poison in vegetable displays throughout the stores. Thus far the Washtenaw County Public Health Department says there have been no deaths but dozens of reports of vomiting and diarrhea are believed to be related to the attack.
