SAN FRANCISCO (AP) -- California's attorney general has field suit against 20 companies, claiming they sold toys containing "unlawful quantities of lead."
The suit alleges that the companies -- including Mattel and Toys "R" Us -- knowingly exposed children to lead and failed to provide warning of the risk.
If the suit is successful, the complaint says the companies could pay a $2,500 fine for each violation.
The move follows major recalls of toys, lunch boxes, children's jewelry and other goods during the last year by the U.S. Consumer Product Safety Commission in Washington.
The suit also names Wal-Mart, Target, Sears, KB Toys, Costco Wholesale and others as defendants.
A Mattel spokeswoman says the company had been expecting the action, and that it has already implemented a system of checks to make sure its quality and safety standards aren't violated again.
