Britax Child Safety has announced a recall of approximately 60,000 car seats.  The company discovered that children can bite off a piece of the harness pad and choke.

The recall covers Boulevard 70-G3, Advocate 70-G3 and Pavilion 70-G3 models.  Approximately 55,455 were sold in the U.S., while about 4,822 were sold in Canada.  The car seats were manufactured between June 11, 2012 and August 31 2012.
