🍼 Attention, Willow Tree Pediatrics Families 🍼
We’re alerting all parents and caregivers about an important safety notification regarding infant formula:
What’s happening?
There have been 13 reported cases of infant botulism in infants who consumed the ByHeart Whole Nutrition Infant Formula.
The outbreak spans 10 states, all 13 infants were hospitalized, no deaths reported so far.
The affected lots are:
Lot 206VABP/251261P2 (Use by: 01 Dec 2026)
Lot 206VABP/251131P2 (Use by: 01 Dec 2026)
The recall is voluntary and precautionary. As of now, there is no confirmed direct link between this formula brand and the illness, and infant formula has never been historically documented to cause infant botulism.
What you should do if you have this product:
Check your formula cans. If they match the lot numbers listed above, stop using them immediately.
Dispose of the recalled formula safely or return it to where you purchased it. If possible, record the lot number before disposal.
Clean and sanitize any bottles, feeding equipment, surfaces, or utensils that may have come into contact with the recalled formula using hot, soapy water or a dishwasher.
If your infant has consumed formula from one of the recalled lots, be vigilant for symptoms and seek medical attention immediately if you notice anything concerning.
Key symptoms of infant botulism to watch for:
Poor feeding or sucking
Decreased muscle tone (“floppy baby”)
Loss of head control
Difficulty swallowing
Weak or altered cry
Constipation
Decreased facial expression
In severe cases: difficulty breathing
Important note: Symptoms can take several weeks to develop after exposure.
Reassurance for families:
Most infants on the recalled formula are not reported ill, and many infants on other formulas are unaffected.
If you’re using a different brand or a different lot of ByHeart formula (not those listed), you’re not impacted by this recall.
If you used the recalled lots and want to contact ByHeart: 1-833-429-4327 or hello@byheart.com
Please check your formula stock as soon as possible, and let us know if you’d like assistance or a consultation. Your baby’s health and safety are our top priority.
