The Similac recall includes:

• all lots of Similac formula powder product lines offered in plastic containers, including 1.38-lb, 1.45-lb and 2.12-lb containers
• certain lots of Similac formula powder product lines offered in sizes such as 8-ounce, 12.4-ounce and 12.9-ounce cans
• Similac formula powder in 8-ounce sample cans that could have been given out in doctor's offices and hospitals

The Similac recall does not affect Similac ready-to-feed or concentrated baby formula or any specialty baby formulas, such Similac Expert Care Alimentum or Similac Expert Care Neosure. Up to 5 million Similac-brand powder baby formulas that were sold in the U.S., Puerto Rico, Guam and some Caribbean countries may be affected by the Similac recall though.
