BROOKLYN, MI -- Columbia Township Police and the FBI are investigating possible food tampering after a syringe was found in a jar of mayonnaise.

A Columbia Township resident bought the of Miracle Whip on Monday, Sept. 16, at the Brooklyn Dollar General, 300 S. Main St., Columbia Township Police Chief David Elwell said.

She came into the police station at 6:15 p.m. that day to report the syringe found in the jar, Elwell said.

The woman told police that after she bought the mayonnaise, she removed the protective seal and placed the jar in the fridge, Elwell said. Her husband removed the jar from the fridge and when he stuck a butter knife in, he felt something hard, he said.

When they looked closer, they discovered the syringe in the jar, Elwell said.

Dollar General removed the remaining jars of the product from its shelves, Elwell said. Columbia Police now have the jars, he said.

The FBI and the U.S. Food and Drug Administration were contacted Monday night, Elwell said. There is ongoing communication between the agencies and the investigation is continuing, he said.
