Two Illinois infants show possible botulism symptoms after using ByHeart formula; recall issued

SPRINGFIELD — Illinois health officials are urging parents and caregivers to stop using certain ByHeart powdered infant formula products after two infants developed symptoms consistent with botulism.

The Illinois Department of Public Health said both infants consumed ByHeart Whole Nutrition Infant Formula, which has since been recalled by the manufacturer. The U.S. Centers for Disease Control and Prevention and the Food and Drug Administration are investigating similar cases in at least 10 other states.

“Parents and caregivers should immediately stop using formula from these recalled lots,” IDPH Director Dr. Sameer Vohra said in a statement.

Recall details

ByHeart Inc. announced Friday it is voluntarily recalling two lots of its Whole Nutrition Infant Formula:

• Lot 206VABP/251261P2 — “Use by 01 Dec 2026”

• Lot 206VABP/251131P2 — “Use by 01 Dec 2026”

Other lots remain under investigation, and additional recalls may follow as testing continues, according to the IDPH.

ByHeart products make up about 1% of the U.S. infant formula market, so the recall is not expected to create supply shortages.

Health officials warn of botulism risk

Botulism is a rare but serious illness caused by a bacterial toxin that can lead to muscle weakness, paralysis, and breathing difficulties. The bacteria can contaminate food even when it appears and smells normal, health officials said.

“Botulism is a serious illness, and we are taking this situation very seriously while working with our federal partners to identify the source and prevent additional cases,” Vohra said.

What parents should do

The IDPH recommends parents and guardians check the lot numbers on any ByHeart powdered formula in their homes and avoid using any recalled products.

Additional guidance and updates are available on the FDA’s website and the CDC’s website.
