Retailers like Walmart and Target ignored a Nov. 11 recall of ByHeart formula, delaying removal despite a botulism outbreak sickening over 50 babies.

The FDA issued warning letters to Walmart, Target, Kroger, and Albertsons for failing to quickly remove ByHeart infant formula from shelves after a Nov. 11 recall tied to a botulism outbreak that sickened over 50 babies across 19 states. Despite the recall, the formula remained available in multiple stores for days or weeks, with evidence of sales and even discounts after the recall, including at Target locations in 20 states. The FDA found no proof of corrective actions from the retailers, who have 15 working days to respond. All affected infants were hospitalized and treated with IV medication. The CDC has expanded the outbreak to include all botulism cases linked to the formula since 2023.
