A stroller manufacturer issued a recall on Tuesday for thousands of baby strollers, citing concerns that a detachable handle in two of the models could lead to falling or choking hazards.

In cooperation with the U.S. Consumer Product Safety Commission and Health Canada, Bugaboo recalled models of its strollers named Chameleon and Donkey after receiving reports that their handles could be disengaged, although no injuries have been reported.

Nearly 50,000 units in the U.S. and nearly 5,000 in Canada have been recalled. Chameleon and Donkey strollers have been available at stores such as Best Buy, Neiman Marcus, Toys R Us and other baby product stores since September 2009. Customers can remove the carry handle and order a replacement handle for free from Bugaboo.
