FDA Expands Infant Botulism Outbreak Linked to ByHeart Baby Formula

Federal health officials have broadened an investigation into an infant botulism outbreak associated with ByHeart baby formula, now encompassing all illnesses reported since the company’s production began in March 2022. The U.S. Food and Drug Administration announced that contamination might have impacted every product manufactured by ByHeart, raising serious concerns about infant safety.

Why It Matters

The expansion of this outbreak to include 51 reported cases across 19 states highlights the critical importance of food safety in infant formula production. With the recent revelations that contamination could date back to the inception of ByHeart, families are increasingly worried about the safety of products meant for their newborns.

Key Developments

• The outbreak now includes at least 51 confirmed cases of infant botulism across 19 states, with the most recent illness reported on December 1.
• The Centers for Disease Control and Prevention (CDC) has broadened the criteria to classify any infant exposed to ByHeart formula since its release as part of the outbreak.
• ByHeart, a company founded in 2016, recalled all products sold in the U.S. on November 11.
• An independent laboratory found contamination in 36 samples from three different lots of ByHeart products.
• The FDA has conducted inspections at ByHeart production facilities but has yet to release findings.

Full Report

Scope of the Outbreak

The CDC’s updated criteria for the outbreak now include any infant exposed to ByHeart formula since its launch. Officials first reported increases in botulism cases tied to ByHeart in August, which led to the current investigation. No fatalities have been confirmed thus far.

Company Response

ByHeart is cooperating with federal authorities and stated that this investigation will aid in diagnosing the root cause of the contamination. The FDA has stated that contamination may have persisted across various production runs and raw material lots, complicating the tracking of the source.

Impact on Families

Concerns are particularly acute among families who have fed their infants ByHeart formula. Parents like Andi Galindo expressed distress upon learning that the contamination might have existed since the product’s introduction. Similarly, Amy Mazziotti, whose son was treated for botulism after consuming ByHeart, noted that being included in the CDC investigation signifies validation of their concerns.

Medical Context

Infant botulism is a rare but serious condition that affects fewer than 200 infants annually in the U.S. Symptoms can manifest as constipation, poor feeding, or weakness and can take weeks to develop. The primary treatment is an intravenous medication known as BabyBIG, developed specifically for this condition.

Context & Previous Events

ByHeart began producing infant formula in 2022 and has faced several challenges. In that same year, the company recalled five lots of formula after a sample tested positive for a different contaminant, cronobacter sakazakii. In 2023, the FDA issued a warning letter identifying areas requiring corrective measures, and one of ByHeart’s facilities was shut down due to severe cleanliness issues, including mold infestations and leaks.

Families affected by infant botulism related to ByHeart have initiated legal action against the company, seeking compensation for medical expenses and emotional strain. The repercussions of this incident cast a long shadow over infant nutrition safety in the United States, underscoring the vital need for rigorous oversight in food manufacturing practices.
