The U.S. Food and Drug Administration is warning health care providers and the public about injuries and at least one death in premature infants who were given probiotic products in the hospital.

The products, which supplement regular feeding and contain live organisms such as bacteria or yeast, can lead to invasive, potentially fatal infections or disease, the FDA said Thursday.

One death this year and more than two dozen reports of injuries since 2018 may be tied to the supplements, FDA officials said in a statement. The agency said it is also investigating additional reports of injuries and deaths.

No probiotic products have been approved as a drug or treatment for babies, the FDA said.
