Atlanta, Georgia – December 10, 2025 – The Centers for Disease Control and Prevention (CDC) today issued a critical update regarding an ongoing investigation into cases of infant botulism. The outbreak, initially connected to ByHeart infant formula, now encompasses cases dating back to december 2023, marking a significant expansion of the timeline.
Expanding Scope of the Investigation
Following collaborative assessments with the California Department of Public Health’s Infant botulism Treatment and Prevention Programme (IBTPP),Investigators have identified a total of 51 infants across 19 states who have been hospitalized and received treatment with BabyBIG®,the standard antidote for infant botulism. Fortunately, no fatalities have been reported to date in connection with the outbreak.
Infant botulism, a rare but serious illness, occurs when an infant consumes clostridium botulinum spores, which than proliferate in the digestive system and produce a perilous toxin. Early symptoms often include constipation, feeding difficulties, a weakened cry, and diminished head control.
Urgent Warning: Discontinue ByHeart Formula Use
The CDC is emphatically urging all parents and caregivers to promptly cease the use of any ByHeart Whole Nutrition infant formula. This recommendation extends even to products that may mistakenly be available for purchase in stores or online. Laboratory analysis has confirmed the presence of botulism spores within the formula, posing a direct health risk to infants.
Rapid Response and Collaboration
Health officials highlight this investigation as a testament to the CDC’s ability to swiftly address emerging threats to public health. On November 7, 2025, the IBTPP alerted the CDC to a concerning increase in infant botulism cases among infants who had been fed ByHeart formula. Dr. Jennifer Cope, Chief of the Enteric Diseases Epidemiology branch, noted that while approximately 150-180 cases of infant botulism are typically observed annually in the United States, an outbreak of this scale is unprecedented.
within hours, CDC and the U.S. Food and Drug Governance (FDA) contacted ByHeart,pressing for immediate action to remove potentially contaminated formula from the market. By November 8th, a nationwide alert was issued, advising parents to discontinue use of specific ByHeart formula lots. Further investigation led to an expanded warning on November 11th, recommending the cessation of all ByHeart infant formula products.
Continued Analysis and Testing
CDC laboratories are now conducting thorough testing of clinical samples from affected infants and samples from opened byheart formula containers obtained from patients’ homes. This rigorous process aims to pinpoint the source of the contamination and further refine public health guidance.
Understanding Infant Botulism: Key Facts
| Factor | Details |
|---|---|
| typical Annual Cases (US) | 150-180 |
| Outbreak as of dec 10, 2025 | 51 Cases in 19 States |
| Treatment | BabyBIG® (Botulism Immune Globulin Intravenous) |
| Primary Symptoms | Constipation, Feeding Difficulty, Weakened Cry, Lack of Head Control |
While this marks the first confirmed outbreak of infant botulism linked to formula, the CDC’s rapid response underscores the agency’s preparedness and commitment to safeguarding infant health. According to the National Institutes of Health, infant botulism is a public health priority due to its potential severity.

Understanding the Recent Botulism Cases
On January 26, 2026, the Centers for Disease Control adn Prevention (CDC) issued a critical public health alert urging parents and caregivers to instantly discontinue the use of ByHeart infant formula. This urgent advice follows an inquiry into a multi-state outbreak of infant botulism, currently linked to 51 confirmed cases across 11 states. the cases have primarily affected infants under six months of age.
Botulism is a rare but serious illness caused by a toxin produced by the bacterium Clostridium botulinum. In infants, it often occurs after consuming food contaminated with the bacteria’s spores. Infant botulism can cause muscle weakness, difficulty feeding, and in severe cases, paralysis and respiratory failure.
Affected ByHeart Products & Lot Codes
The CDC’s investigation has pinpointed a potential source of contamination within specific lots of ByHeart infant formula. Currently, the following products are implicated:
* byheart Whole Nutrition Infant Formula (4oz & 8oz) – Specific lot codes are being updated regularly by the CDC and ByHeart. parents should check the ByHeart website (https://www.byheart.com/recall – this is a placeholder, verify actual URL) and the CDC website (https://www.cdc.gov/botulism/infant-formula-recall-2026.html – this is a placeholder, verify actual URL) for the moast current list of recalled lot numbers.
* ByHeart Gentle Infant Formula (4oz & 8oz) – Similar to the Whole Nutrition formula, specific lot codes are under investigation.
Symptoms of Infant Botulism: What to Watch For
Early recognition of symptoms is crucial for effective treatment.Parents should be vigilant and seek immediate medical attention if their infant exhibits any of the following:
* Constipation: Often one of the first signs.
* Weak cry: A noticeably weaker or less forceful cry than usual.
* Poor feeding: Difficulty sucking or swallowing.
* Lethargy: Appearing unusually sleepy or weak.
* Decreased muscle tone: Floppy or limp body.
* Difficulty breathing: Weakness of the respiratory muscles.
* Generalized weakness: Overall muscle weakness.
These symptoms can develop within 6 to 14 days after consuming contaminated formula, but the timeframe can vary.
What Parents Should Do Now
The CDC and ByHeart are providing clear guidance for parents:
- Stop Using Affected Formula: Immediately discontinue use of any ByHeart formula with a recalled lot code.
- check Lot Codes: Carefully examine the lot code printed on the bottom of the ByHeart formula container. Compare it to the list of recalled lot codes on the ByHeart and CDC websites.
- Contact Your Pediatrician: If your infant has consumed the recalled formula, even if they are not showing symptoms, contact your pediatrician immediately. They can provide guidance and monitor your baby for any signs of illness.
- Report Symptoms: If your infant is exhibiting symptoms of botulism,seek immediate medical attention at the nearest emergency room.Inform healthcare providers that your baby has been consuming ByHeart formula.
- Option Feeding Options: Discuss alternative infant formula options with your pediatrician. do not attempt to make homemade formula, as this can be hazardous and lacks the necessary nutrients.
The Role of the FDA and Ongoing Investigation
The Food and Drug administration (FDA) is working closely with the CDC and ByHeart to investigate the source of the contamination. The investigation is focusing on the manufacturing process and potential points of entry for Clostridium botulinum spores. The FDA is conducting thorough inspections of the ByHeart manufacturing facility and reviewing quality control procedures.
Botulism Treatment for Infants
Infant botulism is typically treated with botulism immune globulin intravenous (BIG-IV). This treatment helps neutralize the botulinum toxin in the infant’s bloodstream. Hospitalization is often required for close monitoring and supportive care, including assistance with breathing if necessary. Early administration of BIG-IV significantly improves outcomes.
Real-World example: 2007 Infant Formula Recall
This outbreak echoes a similar situation in 2007, when a large-scale recall of infant formula occurred due to Salmonella contamination. That event highlighted the critical importance of robust quality control measures in infant formula production and the need for swift and decisive action by regulatory agencies. The current ByHeart situation underscores the ongoing vulnerability of the infant formula supply chain and the necessity for continuous improvement in safety protocols.
Preventing future Outbreaks: Strengthening Infant formula Safety
Preventing future outbreaks requires a multi-faceted approach:
* Enhanced Manufacturing Standards: Stricter regulations and more frequent inspections of infant formula manufacturing facilities.
