Saputo is warning the public not to consume some 4-litre bags of Neilson Trutaste 2% Microfiltered Partly Skimmed Milk, because it might contain a cleaning solution.

The affected product has a best before date of February 12, 2012. The Best Before code 1590 FE12 H7 appears on the bag closure tab. No other codes are affected.

The product has been distributed in Ontario and in Aylmer, Quebec.

The milk should not be consumed, Saputo says. Milk containing this cleaning solution may not look or smell spoiled, but drinking the milk could cause symptoms such as nausea, upset stomach or vomiting, the company warns.

The Canadian Food Inspection Agency says there has been one reaction associated with using this product.
