The Los Angeles County Department of Public Health has issued a grave warning for parents and caregivers about a serious multi-state outbreak of infant botulism. The trigger seems to be the powdered infant formula manufactured by ByHeart Whole Nutrition. According to the Los Angeles County Department of Public Health, these cases are sufficient in number and spread across the states that an immediate cessation of using this product is imperative. Consumers are urged to trash any ByHeart formula they may have or to return it to the place of purchase, and keep a note of the lot number if possible.

In Los Angeles County alone, there has been a confirmed case where an infant required hospitalization. Fortunately, the child is on the mend. But zooming out from the single case locally, a nationwide count since August hits a total of 13 suspected or confirmed cases of infant botulism associated with this formula across 10 states. While no fatalities have been reported, the gravity of the situation cannot be overstated, with each of the affected infants having been fed ByHeart formula according to official reports.

Investigative efforts are underway by a collaboration of local, state, and federal public health agencies, including the California Department of Public Health (CDPH), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA). In the middle of this probe, two lots of the ByHeart Whole Nutrition Infant Formula have been specifically flagged for recall: Lot 206VABP/251261P2 and Lot 206VABP/251131P2, both with a use-by date of 01 Dec 2026. These products were available through various channels, including ByHeart.com and major retailers such as Amazon, Kroger, and Walmart. Despite the company's relatively small market share, the rapid response underscores a serious commitment to consumer safety.

What should you do if you possess this formula? The guidance is clear: stop use immediately. Look out for symptoms such as constipation, muscle weakness, and difficulty feeding, which must be met with urgent medical attention, the department urges. An additional countermeasure parents and caregivers can take is to thoroughly clean any surfaces or objects that might have come into contact with the recalled formula, as recommended by a public health bulletin.

Infant botulism, while rare, manifests as a critical health crisis for the youngest among us – typically, spores of Clostridium botulinum bacteria find a way into an infant’s gut, thriving there and producing a potent toxin. Immediate medical intervention is critical, and healthcare providers are on alert to report any suspicions of botulism without delay. The CDC-approved treatment, BabyBIG®, is fortunately available and can significantly improve an infant’s chances for a swift recovery.

For concerned parents needing further advice or worried about potential exposure, points of contact include their physician and the Public Health InfoLine, which operates daily from 8 a.m. to 8 p.m. at 1-833-540-0473.
