The FBI has arrested a man for sprinkling mice poison and other substances on food in Michigan grocery stores.
The man sprayed a mixture of hand cleaner, water and Tomcat mice poison on produce items within the past two weeks, according to FBI officials.
Investigators said the man possibly struck multiple stores in the Ann Arbor area, including a Whole Foods Market.
The perpetrator, who reportedly confessed, was identified by tips from the public, according to investigators.
The investigation is ongoing and the suspect has said he visited other stores in the Ann Arbor area over the last few months, according to officials.
The FBI is working with Michigan state health officials to determine the threat to the public.
No charges have been announced in the case.
The Michigan Department of Agriculture and Rural Development and Health and Human Services are working with the FBI on this investigation. They are urging people to throw away any foods bought from the salad bars at affected stores.
“Out of an abundance of caution and to protect public health and food safety, I encourage consumers to dispose of any foods purchased from salad bars, olive bars and ready-to-eat hot and cold food areas from these stores between mid-March and the end of April,” said Jamie Clover Adams, MDARD director, in a news release. “Although most of these types of foods may have already been eaten or disposed of, some may still be in refrigerators or freezers.”
