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.
