Canadian dairy products producer Saputo Inc is warning customers not to consume one of its milk products because it could be tainted with a cleaning solution.

Canada's biggest dairy producer said on Friday it is recalling Neilson Trutaste 2% Microfiltered Partly Skimmed Milk, sold in four liter bags, with a best-before date of February 12, 2012.

"Someone drank a bit of the milk and contacted us to let us know that she was suffering from a stomach ache," said Saputo spokeswoman Sandy Vassiadis.

Tests showed that the milk contained a cleaning product used to wash the tanks in the plant where the milk was processed. Vassiadis could not say what the cleaning product was.
