WASHINGTON — Drugmaker Abbott Laboratories said Wednesday it is recalling millions of containers of its Similac infant formula that may be contaminated with insect parts, The Associated Press reported.

The recall affects up to 5 million Similac-brand powder formulas sold in the U.S., Puerto Rico, Guam and some Caribbean countries. The company said the products may contain a small beetle or larvae, which could cause stomach ache and digestion problems. The recall does not affect any liquid formulas or other Abbott-brand products.

The Defense Commissary Agency has pulled all Similac powdered formula from its shelves, a DECA official said Thursday. Customers who have recently purchased such products can return them to their local commissaries for full refunds.

The Army and Air Force Exchange service has also removed the products from shelves, an AAFES official in Europe said. AAFES recommends that customers visit the to find out if the product they have was included in the recall. AAFES customers can return the product to their nearest exchange.
