Nara Organics has recalled its organic baby formula sold at Target stores and online due to a multistate outbreak of infant botulism. Federal authorities report that three babies became ill in California, Pennsylvania and Washington in April and May after consuming the formula. Infant botulism is a rare but serious illness caused by bacteria that produce a toxin in the gut. Symptoms include constipation and breathing problems. The FDA says Nara Organics formula makes up less than 1% of U.S. infant formula sales, so there are no shortage concerns. People are urged to stop using the product immediately.
