This is definitely not the pause that refreshes.

Police in Northern Ireland are investigating what appears to be human feces in a shipment of empty Coca-Cola cans from Germany. Workers on the night shift at the Coca-Cola bottling facility in Lisburn made the unpleasant discovery when the machines that fill the cans clogged.

"It was absolutely horrible, and the machines had to be turned off for about 15 hours to be cleaned," a source told the Belfast Telegraph. "It was unusual because normally the cans come from somewhere else in the U.K., but this time they apparently came from Germany.

Given the large influx of Muslim migrants pouring into Germany, the dominant theory for the messy mishap is being linked to immigrants, though with more charity than most might muster.

"The rumor is that some poor immigrants could have made that long journey in the lorry and that 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?"

Sanitation problems have indeed gone hand-in-hand with massive migration from the Mideast. Last year a German mayor was ridiculed for admonishing the new arrivals not to relieve themselves in gardens, behind hedges and behind bushes. Many migrants had never seen a Western-style toilet before. One manufacturer reportedly has been developing a "multicultural toilet" that includes elements of a Mideastern squat toilet to help immigrants. And while the myreligionislam.com website lists 20 rules and practices "to be followed when answering the call of nature," it says nothing about using Coke cans in a pinch.

Local official Amanda Grehan called the fecal find "shocking."

"If the drinks cans were to get out into shops then it could be extremely dangerous for people," she said.

"But Coca-Cola are a big business in the area and I'm sure they'll do everything necessary to make sure the affected ones don't get out."

"That illegal immigrants could be involved in some way is worrying too, although we're not sure yet if that's the case."

Like the Telegraph's source, Grehan's primary concern was the plight of the immigrants who might have fouled the cans.

"Rather than condemn anyone who might have found themselves in this situation, I think it's far more important that we help anyone who is that desperate and make sure they're safe," she said.

A statement issued by Coca-Cola assured the public "all of the product from the affected production was immediately impounded and will not be sold," and Northern Ireland's Food Standards Agency said "there is no evidence to suggest that any affected product has reached the market."
