Toy-maker Fisher-Price is recalling 83 types of toys — including the popular Big Bird, Elmo, Dora and Diego characters — because their paint contains excessive amounts of lead. The worldwide recall being announced Thursday involves 967,000 plastic preschool toys made by a Chinese vendor and sold in the United States between May and August. It is the latest in a wave of recalls that has heightened global concern about the safety of Chinese-made products. Owners of a recalled toy can exchange it for a voucher for another product of the same value. To see pictures of the recalled toys, visit http://www.service.mattel.com.
