More than 2 million cribs from Evenflo, Delta Enterprise Corp. and five other companies were recalled Thursday amid concerns that babies can suffocate, become trapped or fall from the cribs. Most of the cribs were drop-sides, which have a side rail that moves up and down so parents can lift children from them more easily. That movable side, however, can malfunction or detach from the crib, creating a dangerous gap where babies' heads can become trapped, leading to suffocation or strangulation. The other companies involved in the recall were Child Craft, Jardine Enterprises, LaJobi, Million Dollar Baby and Simmons Juvenile Products. No deaths were linked to the recalled cribs, but there were more than 250 reports of drop-sides detaching or failing and at least 16 entrapments of infants. In one case, a child was found unconscious and later hospitalized. In the announcement from the Consumer Product Safety Commission, all seven companies recalled drop-side cribs. Delta and Child Craft also acknowledged problems with fixed-side cribs. Drop-sides have increasingly come under scrutiny, with several warnings from the CPSC in the last year that the cribs can be deadly. CPSC Chairman Inez Tenenbaum has pledged to ban their manufacture and sale by year's end. “This new recall announcement is part of a larger effort by CPSC to clean up the marketplace from many of these unsafe cribs,” said Tenenbaum. “Most of these recalled cribs have dangerous drop-sides, while the Delta crib can pose a danger to babies if the mattress support is installed incorrectly.” CPSC urged parents to stop using the cribs and contact the manufacturers for repair kits to immobilize the drop-side or information to make the cribs more secure.
