Infant Botulism Outbreak Linked to Recalled ByHeart Formula: What Parents Need to Know

A recent case in Portland, Oregon, has drawn attention to a serious health risk associated with infant formula. A ten-month-old boy, Ashaan Carter, became critically ill due to infant botulism after consuming ByHeart infant formula that had been donated to families in need. This incident has raised significant concerns about food safety, especially for products intended for infants and vulnerable populations.

Infant botulism is a rare but serious condition caused by toxins produced by Clostridium botulinum bacteria. These toxins can cause muscle weakness, difficulty feeding, constipation, and in severe cases, paralysis. In Ashaan’s case, the infection led to severe muscle weakness, inability to lift his head, and the need for a feeding tube. His mother, Angel Carter, described the rapid deterioration of her son’s health, emphasizing the devastating impact this infection can have on families.

The Incident and How It Happened

Ashaan’s mother had been struggling with a low milk supply despite breastfeeding. She received ByHeart formula through the Oregon Department of Human Services, which was intended to help families facing food insecurity. A caseworker informed her that this formula was “closest to breast milk” and could support her infant’s nutrition.

Soon after consuming the formula, Ashaan developed severe constipation and muscle weakness. He was hospitalized twice, first in November and again in December. During his second hospitalization, his condition had worsened, and he required a feeding tube to receive nutrition. Doctors noted that he also needed to relearn basic motor skills, highlighting the severe impact of botulism on infant development.

Federal health officials confirmed that this formula was part of a nationwide recall. The recalled ByHeart products were linked to more than fifty cases of infant botulism across the United States. The company distributed these formulas through its “OpenHearted Initiative,” which provided donations to nonprofit groups supporting low-income and homeless families. Since June 2022, nearly 24,000 cans of formula had been distributed nationwide.

Public Health Response

The U.S. Centers for Disease Control and Prevention (CDC) reported that no new infant botulism cases related to this outbreak have been documented since December 17, 2025. The Food and Drug Administration (FDA) inspected the ByHeart production facilities, but the exact source of contamination has not been disclosed. Production remains suspended until the FDA completes its investigation.

Seattle food safety attorney Bill Marler confirmed that he represents more than thirty families affected by this outbreak. Legal action is ongoing, with at least eighteen lawsuits filed against ByHeart and its distributors. These cases are being coordinated to consolidate claims in federal court, highlighting the broader implications for product safety and liability in the infant nutrition sector.

Understanding Infant Botulism

Infant botulism occurs when spores of Clostridium botulinum grow in a baby’s intestines and release toxins. The condition is more common in infants under twelve months old because their digestive systems are not fully developed and cannot fight off bacterial spores effectively.

Symptoms of infant botulism include:

  • Constipation
  • Weak cry
  • Poor feeding or inability to suck
  • Muscle weakness, especially in the neck and head
  • Reduced movement or floppy limbs

In severe cases, the toxin can affect the respiratory system, making breathing difficult. Early diagnosis and treatment are critical to prevent long-term complications or death. Treatment usually involves hospitalization and administration of botulism immune globulin, which provides antibodies to neutralize the toxin. Supportive care, such as feeding tubes or respiratory support, may be necessary until the infant recovers.

Safety Concerns in Donated Infant Formula

The ByHeart formula involved in this outbreak was part of a charitable initiative aimed at helping families with limited access to infant nutrition. While these programs serve an essential role in public health, the incident highlights the importance of rigorous safety protocols for donated products.

Rachel Alston, executive director of PDX Diaper Bank, one of the groups that distributed ByHeart formula, stated that all partners acted quickly to inform families after the recall. Despite these efforts, some infants were still exposed to the contaminated product, showing that recalls can be difficult to implement in time-sensitive situations.

ByHeart has recalled all formula produced since March 2022 due to potential contamination. Families who may have received these products are urged to monitor infants for symptoms of botulism and contact their healthcare provider immediately if any signs appear.

Lessons for Parents and Caregivers

The outbreak underscores the need for vigilance when introducing formula or other nutritional products to infants. Parents and caregivers should consider the following precautions:

  1. Check for recalls regularly: Stay informed about recalls from the FDA or the manufacturer. Many recalls are announced quickly online, and subscribing to notifications can help families act promptly.
  2. Monitor infant health closely: Watch for early signs of feeding difficulties, constipation, muscle weakness, or lethargy, and seek immediate medical attention if any symptoms arise.
  3. Consult healthcare providers: Discuss feeding options with a pediatrician, especially when considering new or donated formulas. Healthcare providers can recommend safe alternatives if breastfeeding is insufficient.
  4. Understand proper storage and preparation: Follow all instructions for formula preparation and storage, as improper handling can increase the risk of bacterial growth.

Broader Implications for Food Safety

This outbreak highlights gaps in the monitoring of infant nutrition products, especially those distributed through charitable programs. While recalls are a critical tool for public health, they may not reach all families in time, emphasizing the need for preventive measures at the manufacturing and distribution levels.

Regulatory agencies such as the FDA and CDC play an essential role in investigating contamination, issuing recalls, and educating the public. The ByHeart case demonstrates how product contamination can have immediate and long-term consequences for infant health.

Food safety experts stress that rigorous quality control, regular testing, and transparent reporting are crucial in preventing similar incidents. Manufacturers must implement stringent microbial testing protocols to detect contamination before products reach consumers.

The lawsuits filed against ByHeart underscore the legal responsibilities of manufacturers and distributors to ensure product safety. Families affected by infant botulism may face significant medical expenses, emotional trauma, and long-term care needs. Legal action can provide compensation and incentivize companies to maintain high safety standards.

Ethically, companies providing products to vulnerable populations bear an additional responsibility to ensure those products are safe. Donations intended to help families should not compromise quality or safety standards. Public health experts advocate for greater oversight and mandatory testing for all infant formulas, including those donated to charitable programs.

Recovery and Support for Affected Families

Recovery from infant botulism can be prolonged. Ashaan Carter continues to use a feeding tube and is relearning basic motor skills. Recovery times vary depending on the severity of the illness and the age and overall health of the infant. Long-term follow-up care may include physical therapy, occupational therapy, and regular medical check-ups.

Support for affected families is crucial. Parents may need guidance on feeding, developmental milestones, and coping with emotional stress. Healthcare providers and community organizations play a key role in offering resources, education, and emotional support.

The Role of Awareness and Education

Educating parents and caregivers about the risks of infant botulism is essential for early detection and prevention. Awareness campaigns can provide information on safe formula use, proper handling, and recognizing early warning signs. Additionally, healthcare providers can guide parents on safe alternatives when breastfeeding is insufficient.

Public health authorities recommend that families monitor updates from the CDC and FDA regarding infant formula safety. Proactive communication between health agencies, manufacturers, and caregivers can prevent future cases and reduce the impact of contamination outbreaks.

Conclusion

The infant botulism outbreak linked to ByHeart formula serves as a stark reminder of the potential risks associated with infant nutrition products. While charitable programs play a vital role in supporting families, this incident highlights the need for rigorous safety standards, vigilant monitoring, and timely communication during recalls.

Parents and caregivers should stay informed about product recalls, observe infants for early symptoms of botulism, and consult healthcare providers regarding safe feeding practices. Healthcare systems, regulatory agencies, and manufacturers must continue to prioritize safety, quality control, and public education to protect the health of the most vulnerable population infants.

Ashaan Carter’s story is a heartbreaking example of the impact that contaminated formula can have on an infant and a family. It reinforces the urgent need for systemic improvements in infant food safety and for parents to remain vigilant about the products they use to nourish their children.
