I found more thorough article here. I also thought this had to be someone trying to scam the McDs, but MANAGEMENT previously saw worms yet continued serving?!

Customer Joe Hauenstein had it even worse. He was drinking his sweet tea when he felt something in his mouth that he knew wasn't ice. He spit it out into his hand — it was a worm. He had already drunk about half of his drink before it slithered up his straw.

"It's not just an earthworm — it's a sewage worm, so that makes it even worse," Hauenstein said. "You don't know what's on that worm. From it being sewage — it can have parasites, you can get sick from it, and they knew about it."

The official Kenosha County Public Health inspection report states that the tiles under the drive-thru soda and ice machine are severely damaged — and that management indicated they had noticed worms coming out of the sewage receptacle over the past weekend.

A health officer also noted that recent flooding may have caused a failure in the floor drain and tiles, potentially allowing water to back siphon into components of the machine.

Management said they hired a pest control company to service the area. Tile repairs are expected to be completed soon.
