The handle can detach from the shaker, exposing a rough edge and posing a laceration hazard.
The shakers are plastic, 5.5 inches long, with rounded, egg-shaped tops containing steel pellets and open circular handles.
They come in blue and green and are sold separately.
The marking "B4" is printed on the rounded top of each shaker.
They were sold at Mail-order catalogs, websites and retail stores nationwide between August 2010 and March 2011 for about $5.
Consumers should stop using the product immediately and contact the company to receive a refund.
