A nationwide recall of Nara Organics Whole Milk Organic Infant Formula sold at Target and online follows a multistate infant botulism outbreak that sickened three babies aged two to five months in California, Pennsylvania, and Washington during April and May.

The affected infants were hospitalized and treated with an FDA-approved drug for infant botulism; no deaths have been reported.

Nara Organics is Europe-based and accounts for less than 1% of U.S. infant formula sales; officials say the recall is not expected to disrupt the overall U.S. formula supply.

The FDA advises keeping any remaining recalled product in a safe place marked 'Do Not Use' for potential sampling, and discarding or returning it if there are no symptoms or if officials do not need the product.

Authorities urge anyone with an opened can to take these steps and seek medical attention if infants show symptoms, stressing that prompt treatment is critical for infant botulism.

CDC guidance recommends stopping use of the formula immediately for any opened cans, photographing the lot number and use-by date, monitoring infants for symptoms, labeling cans 'DO NOT USE,' storing them separately, and discarding leftovers if no symptoms appear after a month.

For unopened cans, the CDC advises discarding them; for opened containers, document lot numbers and use-by dates and retain remaining product for up to a month for testing, while cleaning all preparation surfaces and bottles with hot, soapy water or a dishwasher.

CDC guidance urges stopping use of any opened cans, documenting lot numbers and use-by dates, labeling the can 'DO NOT USE,' storing away from other baby foods, monitoring infants for about a month, and discarding leftovers if no symptoms after a month.

The CDC issued the recall alert and continues investigations with testing of formula samples expected in the coming weeks.

The FDA notes the recall does not create a shortage risk for parents and caregivers; the formula is manufactured in Europe and sold only in the United States.

The FDA confirms European manufacture and U.S. sale, and notes that infant botulism is rare but serious in babies under one year, linked to bacterial spores in the gut.

Public health officials warn that infant botulism is caused by swallowed spores that grow in the gut and produce toxin, with symptoms including constipation, poor feeding, and weak muscle tone, requiring vigilance.
