Walmart Pulls Formula After Baby's Death Missouri newborn's death may have been caused by tainted formula By Rob Quinn, Newser Staff Posted Dec 22, 2011 2:03 AM CST 7 comments Comments The boy died after being fed formula bought at this store in Lebanon, Missouri. (Getty Images) (Newser) – Walmart has pulled a batch of powdered infant formula from stores nationwide after the death of a newborn boy in Missouri. The retailer says customers who bought 12.5-ounce cans of Enfamil Newborn powder with the lot number ZP1K7G can return them for a refund or exchange. No government recall has been issued but Walmart says it is acting out of an "abundance of caution," the Lebanon Daily Star reports. The boy, 10-day-old Avery Cornett, became gravely ill after being fed powder bought at a Walmart store and died from what doctors believe was a rare bacterial infection that can be caused by contaminated formula. Walmart and the powder's manufacturer say they are making every effort to aid health authorities in their investigation.
