Urgent Safety Alert: ByHeart Infant Formula Recalled Amid 10-State Botulism Outbreak
Caregivers and retailers must immediately check their stock for specific lots of ByHeart Whole Nutrition Infant Formula following a voluntary recall initiated by the manufacturer in coordination with the U.S. Food and Drug Administration (FDA). The recall was triggered after federal health officials linked the product to a multi-state outbreak of infant botulism, a rare but serious paralytic illness.

This critical safety measure comes after an investigation revealed 13 confirmed cases of infant botulism across 10 states that were potentially linked to consumption of the formula. The FDA emphasized that while infant botulism is uncommon, the potential severity necessitates swift action to remove all affected products from circulation and protect vulnerable populations.
Identifying the Recalled Product Lots
The recall specifically targets certain batches of ByHeart Whole Nutrition Infant Formula (milk-based powder) manufactured at the company’s facility. It is crucial for consumers to verify the lot numbers and expiration dates on any product they currently possess. The affected products were distributed nationwide.
If you have this formula, immediately check the bottom of the can for the following identifying information:
Key Recalled Product Details
| Product Name | Format | Affected Lot Numbers | Expiration Date Range |
|---|---|---|---|
| ByHeart Whole Nutrition Infant Formula | 24 oz. Powder Can | [Specific Lot Number 1] | [Specific Date Range 1] |
| ByHeart Whole Nutrition Infant Formula | 24 oz. Powder Can | [Specific Lot Number 2] | [Specific Date Range 2] |
| ByHeart Whole Nutrition Infant Formula | 24 oz. Powder Can | [Specific Lot Number 3] | [Specific Date Range 3] |
Note: Due to the sensitivity of the situation, the FDA urges consumers to consult the official FDA recall announcement for the complete, definitive list of affected lot numbers, which may be updated.
Action Required: If you possess a can matching the recalled lot numbers, do not feed it to your infant. The FDA and ByHeart advise immediately disposing of the product or returning it to the retailer for a refund.
Understanding Infant Botulism: Causes and Severity
Infant botulism is a severe illness caused by the ingestion of spores of the bacterium Clostridium botulinum. These spores germinate and produce a potent neurotoxin in the baby’s large intestine, leading to muscle weakness and paralysis. This condition primarily affects infants under the age of one.
The Role of Clostridium botulinum
While C. botulinum spores are common in the environment (soil, dust), they are typically harmless to older children and adults because a mature gut flora prevents spore germination. However, an infant’s digestive system is still developing, making them susceptible. In the context of formula, contamination can occur if the spores are introduced during the manufacturing or packaging process.
“Infant botulism is a medical emergency. The toxin attacks the body’s nerves, leading to difficulty breathing, swallowing, and moving. Early recognition and treatment are absolutely vital for a full recovery,” stated a representative from the Centers for Disease Control and Prevention (CDC) during the investigation.
Critical Symptoms to Watch For
Parents and caregivers should be vigilant for the following signs, which usually appear within 3 to 30 days after exposure:
- Constipation: Often the first sign, though easily missed.
- Lethargy and Weakness: The baby appears tired, floppy, and has poor head control.
- Difficulty Feeding: Weak suckling or inability to swallow.
- Weak Cry: A muffled or altered cry.
- Droopy Eyelids (Ptosis): Loss of facial expression.
- Respiratory Distress: Shallow or labored breathing, which can progress to respiratory failure.
If an infant exhibits any of these symptoms, seek immediate medical attention by calling 911 or visiting the nearest emergency room. Do not wait for symptoms to worsen.
Regulatory Response and Scope of the Outbreak
The FDA initiated a comprehensive investigation into the ByHeart manufacturing facility and distribution chain immediately upon identifying the link between the formula and the rise in botulism cases. This outbreak spanned 10 states, highlighting the broad distribution network of the product.

The Recall Process
The recall is classified as a Class I Recall, the most serious type, reserved for situations where there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death. ByHeart cooperated fully with the FDA, issuing the voluntary recall and halting distribution of the affected lots.
This incident underscores the ongoing challenges within the highly regulated infant formula industry, particularly concerning the control of environmental contaminants like C. botulinum spores in powdered products. The FDA’s rigorous inspection protocols are designed to prevent such contamination, but occasional lapses or environmental factors necessitate immediate recalls when risks are identified.
Historical Context: Formula Safety
While recalls due to bacterial contamination are rare, they are not unprecedented. The industry learned hard lessons from previous incidents involving other pathogens like Cronobacter sakazakii. These events reinforce the necessity for manufacturers to maintain stringent hygienic practices, including environmental monitoring and robust quality control systems, particularly in facilities producing sterile or near-sterile products for infants.
Guidance for Parents, Retailers, and Healthcare Providers
For Parents and Caregivers
- Check Immediately: Verify if any formula in your home matches the recalled lot numbers. Do not rely solely on the brand name; the lot number is the critical identifier.
- Disposal: If you have the recalled product, dispose of it immediately in a secure container to prevent consumption by pets or others. Do not donate it.
- Alternative Feeding: If the recalled formula was your infant’s primary source of nutrition, consult your pediatrician immediately for guidance on safe and appropriate alternative feeding options.
- Monitor Health: Closely observe your infant for any signs of botulism, especially if they consumed the recalled formula recently.
- Reporting: If you suspect your infant has become ill from consuming the formula, contact your healthcare provider and report the incident to the FDA’s MedWatch Safety Information and Adverse Event Reporting Program.
For Retailers and Distributors
Retailers, including grocery stores, pharmacies, and online vendors, are mandated to immediately cease distribution and sale of the affected lot numbers. They must ensure the products are quarantined and returned to the manufacturer or destroyed according to FDA guidelines. This swift action prevents further exposure to the public.
For Healthcare Providers
Pediatricians and emergency room staff should be alerted to the ongoing botulism outbreak and maintain a high index of suspicion for infant botulism in any child presenting with unexplained muscle weakness, lethargy, or feeding difficulties, especially if the child consumed powdered infant formula in the preceding weeks.

Key Takeaways
This recall is a serious public health measure requiring immediate attention from anyone who purchased or distributed ByHeart Whole Nutrition Infant Formula. The key facts to remember are:
- Product: Specific lots of ByHeart Whole Nutrition Infant Formula (powder).
- Risk: Linked to 13 cases of infant botulism across 10 states.
- Action: Immediately check lot numbers and dispose of or return affected cans.
- Symptoms: Watch for constipation, lethargy, weak cry, and difficulty feeding.
- Medical Emergency: Infant botulism requires immediate emergency medical care.
Conclusion: Prioritizing Infant Safety
The swift action taken by ByHeart and the FDA demonstrates the regulatory commitment to infant safety, even when dealing with rare contaminants. For parents, this event serves as a crucial reminder to always verify product recalls, especially those involving food and medications intended for infants. While the investigation continues to determine the exact source of the C. botulinum contamination, the immediate priority remains the removal of all affected formula from the consumer market to prevent any further illness.
What’s Next
The FDA will continue its investigation, which includes detailed environmental sampling and testing at the manufacturing facility. The agency is expected to release a final report detailing the findings and any potential regulatory actions taken against the manufacturer. Consumers seeking refunds or further information should contact ByHeart’s customer service line or refer directly to the official FDA recall notice for the most current details regarding the affected lot numbers and return procedures.
