The Canadian Food Inspection Agency is warning people not to consume a certain brand of milk that may be contaminated with cleaning products.

Neilson Trutaste 2% Microfiltered Partly Skimmed Milk, with a best before date of Feb. 12, 2012, is being recalled by manufacturer Saputo Inc. of Montreal, Que.

The milk is sold in 4 litre bags and was distributed in Ontario and Alymer, Que.

One reaction has been reported so far.

Any milk contaminated with the cleaning product won't necessarily look or smell spoiled, the agency said.

Consuming it could cause nausea, upset stomach or vomiting.

Affected products have the UPC code 066800 00404 4 and the best before code of 1590 FE12 H7.
