Abbott said parents can identify the recalled products by examining the number on the bottom of each container. The affected formulas have a number starting with 22 through 37, contain K8, SH, or Z2 and have an expiration date of April 1, 2022 or later. The company has also setup a website where parents can check if their products have been recalled:

Abbott, one of the country's largest infant formula makers, said it is recalling all potentially affected products manufactured at the facility. The recall affects certain lots of Similac, Alimentum and EleCare with expiration dates of April 1, 2022, or later. The product was distributed throughout the U.S. and overseas, the company said in a statement.
