A man, whose identity has been withheld, is in custody after officials say he admitted to spraying a contaminating mixture on open food bars at multiple Michigan supermarkets.
The mixture is believed to consist of mouse poison, hand sanitizer, and water.
The FBI released a statement on May 1, requesting the public’s assistance to find the man. Agents said the man is “suspected of attempting to contaminate food products” in local stores.
In the statement, the FBI said a preliminary substance tests on the food sprayed by the chemicals came back negative for harmful contaminants.
An FBI spokeswoman confirmed his arrest, saying the bureau received tips about the man’s identity after releasing surveillance images of him.

Michigan state officials believe anyone who ate the food shouldn’t be physically harmed, but they do recommend throwing out food purchased from open food bars, such as salad bars, olive bars, and ready-to-eat hot or cold bars.
“Although most of these types of foods may have already been eaten or disposed of, some may still be in refrigerators or freezers,” said Jamie Clover Adams, director of the Michigan Department of Agriculture and Rural Development.
The known locations are the Whole Foods, Meijer, and Plum Market locations in Ann Arbor—with food contamination stemming from mid-March to the end of April.
Other locations the man is suspected to have visited are food marts within Flint, Midland, Birch Run, and Saline.
