A disturbing video footage of a mouse running wild inside a bag of McDonald’s burger buns, has emerged.

Karruim Demaio, a former staff member at a Philadelphia branch of Mcdonald’s claims he saw the rodent while on the job and quickly pulled out his mobile phone to record the event.

The shocking video, allegedly shot in a back storage room on November 14, appears to show a mouse scurrying around a bag of hamburger buns making contact with dozens of buns.

Karruim Demaio says he wants to warn customers. He told Fox News: “That wasn’t the first time. That was about the sixth or seventh time. That’s what made me like, I got to get video of this.”

“I was going back there to get something else and I heard some rustling, so I turned around, and I look, I seen a mouse inside the bread. Not on top of the package, but inside of the package,” Karruim Demaio said.

The rodent is clearly visible, with its tail and small feet coming into focus as the mouse wriggles around the buns.

Karruim Demaio, who claims to have worked in the fast food restaurant for more than a year, said the bread was contaminated with droppings on numerous occasions.

The former McDonald’s employee told Fox news: “I was working there from October of 2010 to January of this year. There hasn’t been a time when we couldn’t go in the back and see mouse droppings on the bread.”

Karruim Demaio’s boss allegedly ordered employees to brush off the droppings, and serve the bread to customers.

Another employee confirmed the account, Fox reported. And the second worker says he even saw the general manager brush off the droppings herself.

The manager has denied the accusations, Fox news reported.

Karruim Demaio said he’s worked at two other McDonald’s, and never saw this kind of hygiene issues.

Ken Youngblood, the owner/operator of the McDonalds franchise said: “After viewing the video, we are going to continue to investigate this claim to make certain we have all the facts. I want my customers to know that I am taking this matter seriously and will immediately address any issues that may exist. Therefore, if necessary, we will work with the appropriate authorities to get the facts.”

This particular McDonalds restaurant has a string of health violations dating back at least a year and a half.

According the Philadelphia Health Department, live flies were found in the food prep area; perishable food was not kept cool enough; and refrigeration units were not working correctly.

The report said: “The establishment is not in satisfactory compliance… And current management practices have allowed unacceptable public health or food safety conditions.”
