The ByHeart infant formula has been linked to a botulism outbreak that has affected babies across the country, raising significant health concerns. Laboratory testing of 36 samples from three different lots of the infant formula revealed that five contained strains of the bacteria associated with this rare but dangerous illness.

According to the company, Based on these results, we cannot rule out the risk that all ByHeart formula across all product lots may have been contaminated. The outbreak, which was reported to have begun in August, has already resulted in at least 31 confirmed cases of botulism among infants in 15 states who have consumed the affected formulas.

Botulism in infants can be particularly severe, often presenting with symptoms that include difficulty feeding, drooping eyelids, and weakness. The symptoms may take up to 30 days to manifest after ingestion, making it crucial for parents to remain vigilant.

In addition to the recent cases, reports indicate that infants may have experienced botulism symptoms as far back as November. Medical experts warn that all infants under one year are at risk if they consume contaminated products.

The U.S. Food and Drug Administration has confirmed that some recalled ByHeart products remain on store shelves, despite the nationwide recall initiated by the company on November 11. Parents are urged to cease use of this formula immediately if they have it at home.

The company has initiated a refund policy for those who purchased the product online after August 1 and are now seeking to return it due to safety concerns. As cases continue to grow, families are reminded to report any illness related to the outbreak and to monitor their children closely for signs of distress.
