About 500 frog-shaped piggy banks sold in Canada are being recalled because they contain excessive levels of lead, Health Canada said Wednesday.

The banks, manufactured in China, were sold in San Francisco and San Diego stores across the country.

No associated injuries have been reported.

Consumers should take the banks away from children.

High amounts of lead can harm the kidneys and other major organs. Anemia, a decline in red blood cells, can occur, as well as damage to the nervous system that may impair mental function. Lead poisoning, though rare, can also cause seizures or death.

In recent months, U.S. and Canadian officials have issued a series of recalls of made-in-China toys for safety problems involving lead levels and magnets.
