The Canadian Food Inspection Agency says the cereals have been distributed nationally and there is one reported illness linked to eating them.
All of the Mixed Grains, Oat Cereal and Wheat Cereal products are sold in 227 gram green and white packages.
The CFIA says if the cereal has an unusual odour or smells "off ," it should not be used.
And, if an infant has been fed any of the products, parents should stop using the cereal and monitor the child for symptoms.
Eating rancid food may cause symptoms such as nausea, vomiting and diarrhea.
Loblaw Companies is voluntarily recalling the affected products from stories and the CFIA is monitoring the effectiveness of the recall.
