A company is recalling Koala's March creme-filled cookies from U.S. shelves because they were made in China and may be contaminated with melamine.

Lotte USA Inc. says Friday that it initiated the recall on Sept. 29. The Michigan-based company says it's not aware of any illnesses associated with the products.

The recall covers king-size chocolate, white chocolate and strawberry flavors. It also includes family pack-size chocolate, white chocolate, strawberry, chestnut, Hawaii chocolate and Hawaii pineapple flavors.

Cookies were distributed nationwide and to Canada.

Melamine is the industrial chemical blamed for killing four infants and sickening 54,000 children in China. It's used to make plastics and fertilizers.
