WASHINGTON — L.L. Bean began recalling two lines of children’s overalls Tuesday after determining that children could choke on the overalls’ snaps.

The Consumer Product Safety Commission said the snaps could be pulled free of the garment in the 7,700 pairs of overalls recalled.

The recall covers L.L. Bean’s traditional blue denim overall, sold in sizes 6 months through 4T, and the company’s cotton twill woodland overalls, lined with red flannel and sold in sizes 6 months through 3T.

Customers can identify the traditional style by a full snap crotch, pockets and a sewn-in label reading “0DB48.” The woodland overalls have a full snap crotch, a front zipper, pockets and a sewn-in label reading “0HS39.”

L.L. Bean sold the overalls for $20 to $26 during 1999 from their catalog, World Wide Web site and outlet stores.

Though no injuries have been reported, the company has received six complaints.
