Some two million baby pushchairs are being recalled by baby product maker Graco after reports that four infants died in the strollers.
The US Consumer Product Safety Commission said four babies had been strangled between 2003 and 2005 after becoming trapped in the pushchairs.
The company is recalling Graco Quattro Tour and MetroLite strollers manufactured before 2007.
Those who purchased the product should contact Graco and request a repair kit.
The CPSC says if babies are not strapped properly into the strollers distributed by Graco Children's Products Inc, they could slide through the opening between the stroller tray and the bottom of the seat - an area where they risk being stuck and strangled.
The strollers being recalled by Graco were sold in the US between November 2000 and December 2007.
