Illinois health officials are urging parents and caregivers to immediately stop using certain lots of ByHeart Whole Nutrition Infant Formula following a connection to a multi-state outbreak of infant botulism. The Illinois Department of Public Health (IDPH) issued this alert after preliminary tests confirmed the presence of bacteria that produce botulism toxin in samples of the formula.
The recall involves two specific lots of ByHeart Whole Nutrition Infant Formula:
- Lot 206VABP/251261P2 (“Use by 01 Dec 2026”)
- Lot 206VABP/251131P2 (“Use by 01 Dec 2026”)
These lot codes and “Use by” dates are found on the bottom of the infant formula can. ByHeart makes up less than 1% of all baby formula sold in the United States, so this recall is not expected to impact nationwide supply.
Thirteen cases have been reported across ten states so far, including two possible cases in Illinois. The FDA, CDC, and state health departments are continuing their investigation. Preliminary tests confirmed the botulism-causing bacteria, but additional testing of formula samples is ongoing.
What Should Parents Do?
- Immediately stop using the recalled formula and dispose of it or return it to the store.
- Clean all bottles and surfaces that may have come into contact with the formula.
- If your infant is not feeling well, especially after consuming any of these batches, contact your healthcare provider.
- Record the lot code and “Use by” date before throwing away the product for reference.
Symptoms to Watch For
According to the CDC, symptoms of infant botulism include:
- Constipation
- Poor feeding
- Loss of head control
- Difficulty swallowing
- Decreased facial expression
Symptoms may take weeks to appear after ingesting contaminated formula. The condition can worsen to breathing problems and even respiratory arrest, so immediate medical attention is critical.
If you suspect infant botulism in a patient, call 510-231-7600 for immediate case consultation. Support is available 24/7.
