Drugmaker Abbott Laboratories said Wednesday it is recalling millions of containers of its best-selling Similac infant formula that may be contaminated with insect parts.
The voluntary action 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.
A company spokeswoman said Abbott uncovered the insects last week in one section of a manufacturing plant in Sturgis, Michigan.
"We immediately shut down that one area and began an investigation," said Abbott's Melissa Brotz. "We're in the process of resolving it now." Abbott manufactures Similac at several U.S. sites.
