Police have launched an investigation after “human waste” was found in a shipment of Coke cans.

The grim find was made at the Knockmore Hill facility in Lisburn, Ireland — but Coca-Cola has confirmed that none of the products on sale at the moment are affected.

A massive cleanup had to be performed after the shipment arrived from a German supplier the Irish facility had not worked with previously.

A source told the Irish Independent that it was "absolutely horrible, and the machines had to be turned off for about 15 hours to be cleaned.

“It was unusual because normally the cans come from somewhere else in the U.K., but this time they apparently came from Germany.”

The cans reportedly arrived on a truck from Germany where immigrants used the cans as a toilet on the long journey across Europe.

As the source told the paper, “The rumour is that some poor immigrants could have made that long journey in the (truck) and … in their desperation were forced to use the cans instead of a toilet.

“It’s really shocking — and beyond the shock of finding something pretty disgusting in the cans is the thought there could have been poor people in that situation.

“And if they did make that journey, where are they now?”

According to the Police Service of Northern Ireland, “Detectives are investigating an incident at commercial premises in the Lisburn area following reports that a consignment of containers delivered to the premises had been contaminated.

“The investigation is at an early stage and there are no further details available at this time.”

Coca-Cola has since responded to concerns, saying, “The problem was identified immediately through our robust quality procedures and all of the product from the affected production was immediately impounded and will not be sold.

“This is an isolated incident and does not affect any products currently on sale.”

Coca-Cola was the subject of a "Dispatches" investigation on Britain's Channel 4 that looked into the company's plans to fight the U.K. "sugar tax," which will be implemented in 2018. The sugar content of each can was also highlighted in an experiment which went viral last week, after a Youtuber boiled the drink down into a syrupy substance.
