Quirky World ... Cheese factory workers bathe in milk vats

A criminal investigation has been launched into breaches of hygiene at a cheese factory after footage of bare-chested workers bathing in vats of milk went viral on the internet.

The Investigative Committee announced it was probing the factory in the Siberian city of Omsk for producing food that could cause harm to health, after photographs of grinning workers bathing in foaming milk horrified Russians.

“It has already been established that the liquid that the factory workers were bathing in was the raw milk that was used for making the cheese,” the investigators said in a statement.
