A leading producer of children's products is recalling about 2 million baby strollers sold before 2008 at major U.S. retailers, after four infants died of strangulation.

The news of the recall by Graco Children's Products Inc, of the China-made strollers, comes less than three weeks after Mattel Inc's Fisher-Price recalled some 10 million toys and other items, renewing concerns about safety standards of infant products -- a good chunk of which is made in low-cost centers like China.

The latest recall, made along with the U.S. Consumer Product Safety Commission, applies to Graco Quattro Tour and MetroLite strollers sold at retailers including Babies R Us, Sears, Target and Wal-Mart between November 2000 and December 2007.

In addition to the four deaths, the CPSC said it was also aware of reports of five infants becoming entrapped, resulting in cuts and bruises, and one having difficulty breathing.

"This recall involves strollers sold as long as 10 years ago, demonstrating the ongoing need for families to remain vigilant about hazardous products lurking in their homes," said Dan Verakis, founder and CEO of SafetyBook.org, which runs a recall-monitoring service for consumers.

Earlier this year, Graco recalled another 1.5 million strollers after the CPSC received reports of children's fingertips being amputated.
