Mattel Inc. is recalling 4.4 million Polly Pocket toys with magnets(磁铁)after some of them caused serious injuries to children who swallowed magnets that fell off.

Tiny magnets inside the toys may fall off without being noticed by parents and babysitters. The magnets can be swallowed or placed in children’s noses or ears. When more than one magnet is swallowed, the magnets can attract each other and cause intestine perforation(肠内穿孔)which can be deadly.

The Consumer Product Safety Commission(CPSC)received 170 reports of the small magnets coming out of these recalled toys. There were three reports of serious injuries to children who swallowed more than one magnet. All three suffered intestinal perforations that required operation. A 2-year-old child stayed in hospital for seven days and a 7-year-old child was hospitalized for 12 days. An 8-yeal-old child was also hospitalized.

The recalled Polly Pocket toys contain plastic dolls and accessories(附件)that have small magnets. The magnets measure one-eighth inch in diameter and are fixed in the hands and feet of some dolls, and even in the plastic clothing, hairpieces and other accessories to help the pieces stay on the doll or the doll’s house.

The model number is printed on the bottom of the largest pieces on some of the toys. Contact Mattel if you cannot find a model number on your product to determine if it is part of the recall. Polly Pocket magnetic toys currently sold in stores are not included in this recall. The model numbers included in the recall are: B2632, B3158, B3201, B7118, G8605, H1537, H1538 and H3211. The toys were on sales in department stores and toy stores from May 2006 through September 2009 for between $15 and $30.

Consumers should immediately take these recalled toys away from children and contact Mattel for the return of the toys. For more information contact Mattel at 888 597-6597 anytime or visit the company’s Web site.
