Abbott [baby formula manufacturer] voluntarily recalled several of its baby formula products after four infants reportedly got sick. The powder formulas were distributed across the country, and possibly exported to other countries, the Food and Drug Administration said.

The powder formulas impacted by the recall include Similac, Alimentum and EleCare. To identify if you have a package affected by the recall, check the number on the bottom of the container. If it starts with digits 22 through 37 and contains K8, SH or Z2, and has an expiration of April 1, 2022, or later, it should be thrown out. All of the recalled formula was produced at the company's Sturgis, Michigan, facility, the company said.

Abbott has set up a web page where you can check if your powder formula's lot number is included in the recall: https://www.similacrecall.com/us/en/product-lookup.html. Consumers can get more information at www.similacrecall.com on how to obtain a refund or replacement, or call Similac customer service at 1-800-986-8540.
