Stop using ByHeart Whole Nutrition Infant Formula right away. According to the California Department of Public Health (CDHPH), ByHeart Inc. has recalled the formula because it has been linked to infant botulism in multiple states.
What is infant botulism?
It mostly happens to babies under 1 year old. With quick care, most babies recover. Currently, ByHeart is the only baby formula linked to infant botulism.
Which formula is affected?
On Nov. 8, 2025, ByHeart Inc. recalled two lots of the formula. The Center for Disease and Control (CDC) says to stop using any ByHeart formula right away. This means:
- All lot numbers.
- All sizes of cans and single serve packets.
What should you do?
According to the CDC, if you have ByHeart formula:
- Wash any items and surfacesthat touched the formula with hot, soapy water or use a dishwasher.
- Take a photo of the lot number and “use by” date if you can.
- Label leftover powder “DO NOT USE” and keep it in a safe place for at least a month.
- If your baby develops symptoms of infant botulism, your state health department may need the formula for testing.
- If your baby has no symptoms after a month, throw the formula away.
Early signs of infant botulism
If your baby has had ByHeart formula from the affected lots, watch for these early signs of infant botulism:
- Constipation.
- Weak cry or poor head control.
- A hard time feeding, sucking or swallowing.
- Less facial movement.
- Muscle weakness or trouble breathing.
Get medical help right away if your baby has had ByHeart formula and any of these symptoms. Tell your baby’s provider that they had ByHeart formula.
