Mead Johnson and Co. is recalling about 41,500 cans of its Gentlease powdered infant formula because they may contain small metal particles.

The Evansville, Ind., company has not reported any injuries, but the metal particles could seriously harm a baby’s throat and respiratory system. Symptoms could include coughing and difficulty breathing or swallowing. Any symptoms would be likely to appear within three to four hours of feeding.

The recalled 24-ounce cans of formula were stamped on the bottom with lot code BMJ19 and “use by” date 1 Jul 07. They were sold at major retail stores nationwide.

Parents who have fed some of this batch of Gentlease to their baby and are concerned about their child’s health should contact their doctor.

Consumers who have cans of this batch of Gentlease should stop using them immediately and call Mead Johnson for more information at (888) 587-7275.
