A father in Davis County, Utah, claims he needed to be taken to the hospital after drinking an unidentified liquid that was inside a bottle of chocolate milk he purchased from McDonald's.

Seadur Kopczuk bought his family food from a McDonald’s location in Farmington, KSL reports. But before handing his son the chocolate milk, Kopczuk decided to take a drink of it himself, and he alleges that he immediately noticed something was wrong with it.

At first, he claims he thought the milk may have been rotten, but the family says they found a clear, foul-smelling liquid inside the container. When Kopczuk started to complain that his chest felt like it was burning, his family decided to take him to the hospital. He reportedly recieved treatment for poisoning but was released after a few hours, and claimed he still didn’t feel right.
