The Canadian Food Inspection Agency is advising consumers to inspect infant formula containers before buying them, following complains that some bottles were tampered with in stores west of Toronto.

Bottles of Enfamil A+ Ready-to-Feed Infant Formula sold in Wal-Mart were found with the tamper-proof seal broken and blue tape applied in its place, CFIA said in a food safety warning advisory.

The bottles that were tampered with contained water and some formula residue instead of infant formula, CFIA said.

Three complaints have been reported in Brampton and Mississauga. There have been no confirmed illnesses related to the product.

Wal-Mart immediately removed the product from sale in a number of stores in the Halton and Peel regions, CFIA said. It did not find any additional product that had been altered.

CFIA advises consumers to examine the containers to make sure that the security seal is intact and has not been altered. The agency says people should not use the product if it appears to have been altered, but instead throw it out or return it to the store where it was purchased.

CFIA said it is working closely with Walmart Canada Corporation and Mead Johnson Nutrition (Canada) Company and is investigating.
