ByHeart Formula: Years of Contamination Feared
11 Dec, 2025
Summary
- All ByHeart formula ever produced may be contaminated.
- Outbreak now includes 51 infants across 19 states.
- Company faces lawsuits over alleged defects and negligence.
Federal health officials have issued a concerning update regarding an infant botulism outbreak, stating that all ByHeart baby formula produced since its inception in March 2022 may be contaminated. Investigations by the FDA and ByHeart are actively seeking the root cause of the contamination.
The expanded scope of the probe now encompasses at least 51 infants across 19 states, with the latest reported illness in December 2025. Cases have been reported nationwide, with California and Texas having the highest numbers. ByHeart, a small market share manufacturer, recalled all its products on November 11th.
This news has caused distress for parents who trusted the formula's "natural" and "gentle" reputation. Families have initiated lawsuits, alleging the formula was defective and that ByHeart acted negligently. Past inspection documents reveal previous contamination issues and a warning letter from the FDA in 2023.
