Federal authorities are reducing the frequency of reports on the infant botulism outbreak traced to ByHeart powdered infant formula.
So far the outbreak has sickened 51 babies across 19 states. All of the babies have required hospitalization but none have died. The Centers for Disease Control and Prevention has determined that some of the illnesses date back to December 2023. It was originally thought that the outbreak began in August this year.
According to the Food and Drug Administration reports of illnesses in the outbreak have slowed since the most recent update on Dec. 10. Therefore, the CDC will no longer be releasing weekly updates. Rather, the agency will only update the public “when new information becomes available.”
As of Nov. 11, all ByHeart products have been recalled. On Dec. 12 the FDA sent letters to officials at Albertsons, Kroger, Target and Walmart warning them because they had not promptly removed the recalled products from their store shelves and that such inaction was a violation of federal law.
The recalled ByHeart formula was available at other retailers and via online sales.
Testing by the California Department of Public Health, as well as ByHeart, found botulism in the company’s infant formula.

Symptoms of Infant botulism
Most infants with infant botulism will initially develop constipation, poor feeding, loss of head control, and difficulty swallowing, which can progress to difficulty breathing and respiratory arrest. Symptoms of infant botulism, which is diagnosed clinically, can take as long as several weeks to develop following formula ingestion.
Any infants with signs of botulism should be immediately taken to a doctor or emergency room.
