Infant Botulism Linked to ByHeart Ingredient Supplier

Health officials found spores that can cause infant botulism at a supplier for formula-maker ByHeart Inc. as part of their investigation into an outbreak that sickened dozens of babies in the US, the Centers for Disease Control and Prevention said Friday.

Food and Drug Administration testing identified the spores in a whole milk powder at a ByHeart supplier. The supplier wasn’t named. The tests also found links between samples from one of the infants involved in the outbreak and the whole milk powder, according to the CDC.
