US retail group The TJX Companies has recalled 23,600 of its Emma's Garden Polka-Dot girls' dresses in the US and Canada due to a choking hazard.

The decorative buttons on the front of the dress can detach, a statement said, posing a choking hazard. No injuries have yet been reported.

The US Consumer Product Safety Commission and Health Canada, in cooperation with TJX, announced the voluntary recall yesterday (15 June).

It said consumers should stop using recalled products immediately unless otherwise instructed, and return for a refund.

The recall includes the Emma's Garden polka-dot dresses in sizes 12 months to 5T sold in black and white and pink and white. Dresses sold in the United States have neck tags bearing tracking number TJX-80327TDS1.

The company sold 21,000 of the dresses in the US and 2,600 in Canada.

TJ Maxx sold the pink and white design and Marshalls sold the black and white design in the US from February 2011 to May 2011 for about $13. Winners stores sold both designs in Canada, from March 2011 to April 2011 for about $17.

The dresses were manufactured in China.
