Perrigo Co. said it discovered the metal bits during quality-control checks. The company passed 70 million pills through a metal detector and discovered the metal in about 200 caplets, according to the Food and Drug Administration. The fragments ranged in size from "microdots" to portions of wire one-third of an inch long.

The recall affects bottles containing various amounts of 500-milligram caplets.

Perrigo bills itself as the world's largest manufacturer of store-brand nonprescription drugs. The Allegan, Mich., company did not disclose the chains for which it manufactures the store-brand acetaminophen. A list of batch numbers and store brands affected by the recall was forthcoming, the FDA said.

Wal-Mart Stores Inc. (WMT), CVS Corp. (CVS), Walgreen Co. (WAG) and Costco Wholesale Corp. (COST) are among the companies Perrigo supplies with health care products, according to company Securities and Exchange Commission filings.

Perrigo (PRGO) said the pills contained raw material purchased from a third-party supplier and affected 383 batches.

Acetaminophen is best known as the drug in products sold under the Tylenol brand, but is widely available in generic versions. The recall does not affect Tylenol. The recall should not cause a shortage of acetaminophen, the FDA said.

The voluntary recall is considered a Class II recall since it covers products that might cause a temporary health problem or pose only a slight threat of a serious nature, according to the FDA.

Consumers with questions can call Perrigo toll free at (877) 546-0454.

Consumers who swallow any of the contaminated pills could suffer minor stomach discomfort or possible cuts to the mouth and throat, the FDA said, adding that the risk of serious injury was remote. Anyone who suspects they have been injured should contact their doctor, the agency said.

The FDA said Perrigo began investigating after realizing the equipment it uses to make pills was wearing down prematurely.
