The Canadian Food Inspection Agency says Shoppers Drug Mart is recalling certain Abbott brand powdered infant formula products from the marketplace.

The warning indicates that several powdered infant formula products could be tainted with salmonella or possibly some other microbial contamination.

The products had been previously recalled on February 17th but some of it was sold in error, online.

The recall involves four Similac products, including the iron-fortified powder, hypoallergenic infant formula, and iron-fortified and calcium-enriched powder.
