Abbott recalls beetle-tainted Similac baby formula

Brotz said fewer than 5 million units of Similac are being recalled in the United States, Guam, Puerto Rico and other Caribbean markets.

"When we identified this, we did extensive testing of every product on the (factory) line, and more than 99.8 percent of the product was negative" for beetle contamination, Brotz said. She noted that liquid forms of Similac have not been affected or recalled.

But all powdered product made on the Michigan factory line is being recalled due to the remote possibility of contamination, said Brotz. She described the pest as a common beetle indigenous to houses, office buildings and grocery stores.
