A baby formula company has admitted that all of its products may be contaminated with deadly botulism bacteria after 31 infants across 15 states fell seriously ill, exposing yet another regulatory failure that puts America’s most vulnerable at risk.
Story Highlights
- ByHeart admits all baby formula products may be contaminated with botulism bacteria.
- 31 infants in 15 states were sickened, with symptoms including breathing problems and paralysis.
- The FDA failed to prevent continued sales despite a nationwide recall.
- Parents are filing lawsuits against the company for negligence and defective products.
Company Admits Widespread Contamination Risk
ByHeart revealed in a November 24, 2025, statement that five of 36 formula samples tested positive for Clostridium botulinum Type A, the bacteria causing potentially fatal botulism. The company acknowledged it “cannot rule out the risk that all ByHeart formulas across all product lots may have been contaminated.”
This admission comes after weeks of attempting to contain what appeared to be isolated incidents, revealing the scope of contamination may be far broader than initially disclosed.

Infants Suffer Severe Neurological Symptoms
The FDA documented at least 31 cases of infant botulism linked to ByHeart Whole Nutrition formula across 15 states as of November 19. Affected babies experienced alarming symptoms, including poor feeding, loss of head control, drooping eyelids, flat facial expressions, and difficulty swallowing or breathing.
The Centers for Disease Control warns these neurological symptoms can take weeks to develop, meaning more cases may emerge as the bacteria’s effects manifest in vulnerable infants.
Regulatory Breakdown Allows Continued Sales
Despite issuing a nationwide recall earlier in November, the FDA reported on November 20 that contaminated ByHeart formula remained available at major retailers. This regulatory failure demonstrates the inadequacy of current oversight systems designed to protect consumers from dangerous products.
The continued availability of recalled formula puts additional infants at risk, while parents may unknowingly purchase contaminated products, highlighting the need for more aggressive enforcement mechanisms and retailer accountability.
Parents Seek Justice Through Legal Action
Multiple lawsuits have been filed against ByHeart by parents whose children suffered from the contaminated formula. The legal actions allege the company was negligent in selling defective products and seek compensation for medical bills, emotional distress, and other damages.
ByHeart has offered full refunds for products purchased through their website after August 1, while stating they continue investigating their entire supply chain from raw ingredients through transportation to identify the contamination source.
