The recall of ByHeart powdered infant formula has become a pivotal moment in U.S. product-safety and infant health because it involves a very rare disease, infant botulism, linked to formula that normally would not be expected to carry such a risk.
The national inquiry began when the California Department of Public Health and federal agencies flagged that one previously opened can of ByHeart Whole Nutrition Formula tested positive for spores of Clostridium botulinum, the bacterium that produces a neurotoxin causing paralysis in babies.
Although infant botulism is exceedingly rare and historically associated with environmental exposures (not formula), this outbreak triggered a broad voluntary recall of all ByHeart Whole Nutrition Infant Formula products sold nationwide, including both cans and single-serve “Anywhere Pack” pouches.
The fact that no other infant formula brands have been implicated thus far, despite the ongoing investigation, makes this incident unique and deeply concerning.
The Food and Drug Administration (FDA) is coordinating with the Centers for Disease Control and Prevention (CDC) and state health partners to trace how powdered infant formula exposure may have allowed C. botulinum spores to germinate and produce toxin in vulnerable infants.
ByHeart represents only about 1 % of U.S. infant formula sales yet is disproportionately represented among sick infants.
Parents and caregivers of infants who consumed this specific powdered infant formula are being urged to immediately discontinue use and monitor for warning signs of illness.
Below is a timeline of events related to the ByHeart formula recall:
- Mid-August 2025: First hospitalizations of infants with suspected or confirmed infant botulism following consumption of ByHeart formula.
- November 8, 2025: ByHeart issues initial voluntary recall of two specific lots of its Whole Nutrition Infant Formula.
- November 11, 2025: Recall expanded to include all unexpired lots of ByHeart Whole Nutrition infant formula (including powder cans and Anywhere Pack pouches) nationwide.
- November 14, 2025: CDC and FDA report 23 infants in 13 states hospitalized with suspected or confirmed infant botulism after using ByHeart formula; no deaths reported to date.
- November 19, 2025: FDA/CDC revised count is 31 infants in 15 states with confirmed exposure to ByHeart formula; all hospitalized; no deaths reported.
- Currently: As of November 24, 2025, 31 infants have been hospitalized after consuming ByHeart formula across 15 states (no deaths reported).
- FDA reports 84 infant botulism cases detected since August, of which a significant share consumed powdered formula (with ByHeart disproportionately represented).
- ByHeart begins batch-by-batch third-party testing, gives full facility access to regulators, and advises parents to stop use immediately.
- Agencies urge “immediately discontinue use” of any ByHeart powdered infant formula and to seek immediate medical attention for infants showing possible symptoms.
Infant botulism is a severe, life-threatening condition in babies whose guts are not yet able to handle C. botulinum spores, and this outbreak potentially represents the first confirmed link between formula exposure and such illness.
Historically, powdered infant formula has faced microbial risk (e.g., Cronobacter), but the possibility of toxin-producing spores in formula elevates the threat to a new level of urgency.
Because infants are uniquely vulnerable, the speed of hospitalization in affected babies and the need for specialized treatment (such as antitoxin) underscore the high stakes.
Regulatory gaps in monitoring and microbial control of powdered infant formula are now under intense review, and manufacturers of other infant formula brands are likely paying attention.
For affected families, the disruption extends beyond immediate illness.
Long hospital stays, respiratory support, developmental monitoring, and emotional trauma are all possible outcomes.
As such, this recall and investigation demand swift, informed action from caregivers, health professionals, and lawyers alike.
What ByHeart Brand Formula Has Been Recalled?
The recall of the ByHeart baby formula centers on its Whole Nutrition Infant Formula line, specifically both the 24 oz cans and the single-serve Anywhere Pack™ powdered infant formula products.
The company initially recalled two specific batches (lot codes 206VABP/251261P2 and 206VABP/251131P2, Use by 01 Dec 2026) after epidemiologic and laboratory data linked infants who consumed these formulas to confirmed or suspected infant botulism cases.
Following additional findings from federal and state health authorities, ByHeart expanded the recall on November 11, 2025 to include all unexpired batches of its Whole Nutrition Infant Formula sold nationwide.
The FDA’s updated recall notice confirmed that an opened can from one of the recalled lots tested positive for Clostridium botulinum spores, though no unopened cans have yet tested positive.
The expansion was conducted in cooperation with the Food and Drug Administration (FDA) and the California Department of Public Health, with ByHeart granting investigators full access to its facilities and committing to independent third-party laboratory testing of all product batches moving forward.
Recalled ByHeart product(s):
- ByHeart Whole Nutrition Infant Formula – 24 oz cans (UPC 85004496800) – all unexpired batches nationwide.
- ByHeart Whole Nutrition Infant Formula – Anywhere Pack™ single-serve sticks (UPC 85004496802) – all unexpired batches nationwide.
If you have any of these ByHeart powdered infant formula products, it is important that you immediately discontinue use and securely dispose of the formula, while monitoring your child for any symptoms of infant botulism and seeking medical attention if needed.
How Many Cases of Infant Botulism Linked to ByHeart Formula Have Been Reported?
The number of infant patients reported in connection with the ByHeart powdered formula investigation has grown as the outbreak evolves.
According to the Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC), approximately 13 infants across 10 U.S. states were initially hospitalized after consuming ByHeart Whole Nutrition formula.
More recently, updates show the total has increased to 31 infants in more than a dozen states, all of whom had exposure to ByHeart brand powdered infant formula.
These infant patients represent a disproportionately high share of cases in this outbreak of infant botulism linked to powdered formula exposure.
The FDA reports that of about 84 total infant botulism cases under investigation since August 2025, 36 involved powdered formula, and more than 40% of those consumed ByHeart formula.
All of the affected infants were hospitalized, though no deaths have been reported to date.
Is ByHeart Facing Lawsuits Over the Formula Recall?
ByHeart is now the subject of active legal claims following the nationwide recall of its powdered infant formula after a documented outbreak of infant botulism.
According to a report by CBS News, two federal lawsuits were initially filed by parents of four-month-old daughters, one in Arizona and one in Kentucky, who were diagnosed with botulism after consuming the company’s product.
The complaints allege that the ByHeart formula the infants consumed was defective, and that ByHeart was negligent in manufacturing and selling it despite epidemiologic and laboratory data linking the product to illness.
According to one parent’s account, her child had consumed an entire can of the recalled ByHeart powdered formula just one day before the recall was publicly announced.
ByHeart acknowledged the recall and expressed sympathy for the families affected, but stated they “would address any legal claims in due course.”
Now, at least five separate lawsuits have been filed against ByHeart, including a proposed class action lawsuit.
The class action claims that parents were misled by marketing which positioned the formula s a premium “healthy alternative”, when in reality the formula was defective and the company failed to ensure safe manufacturing and testing.
ByHeart’s Response and Growing Scrutiny Over Manufacturing Safety
Reporting from STAT shows that ByHeart’s early statements downplayed the link between its formula and the infant botulism cases, even as health officials connected multiple hospitalizations to the product.
The company initially pointed to negative tests from unopened cans, but experts note that powdered formula contamination can appear inconsistently and may not be detected in every sample.
The FDA later confirmed that an opened can had tested positive for Clostridium botulinum spores, which led to the expanded recall covering all unexpired lots of ByHeart Whole Nutrition Infant Formula.
This incident follows earlier issues with ByHeart’s production oversight.
In December 2022, the company recalled five batches of its formula due to potential Cronobacter sakazakii contamination.
In August 2023, the FDA issued a formal Warning Letter citing failures in ByHeart’s microbial controls, environmental monitoring, and record-keeping , including findings that formula with potential contamination risks had been distributed commercially.
With the current outbreak linked to ByHeart products, regulators are reviewing the company’s manufacturing processes, sanitation controls, and testing methods across multiple years of operations.
The FDA has gained full access to ByHeart’s facilities, and the company has begun batch-by-batch third-party testing as part of the ongoing investigation.
These documented issues, combined with the formula-linked botulism cases, are now a central focus in evaluating whether preventable safety failures contributed to the outbreak.
