The FDA and CDC are investigating a multistate outbreak of infant botulism linked to ByHeart Whole Nutrition infant formula. All ByHeart infant formula products, including cans and single‑serve “anywhere pack” sticks, have been recalled and should not be used, sold, or purchased. Parents and caregivers should check their homes for ByHeart formula and throw it away or return it to the store. If your baby has consumed ByHeart formula and develops constipation, poor feeding, weak head control, or trouble breathing, seek medical care immediately and tell your provider about the possible exposure.
