A growing number of infant botulism cases linked to ByHeart infant formula have received increased national attention, according to recent reports from state and federal health agencies. The outbreak began in August, and at least 31 infants in 15 states have been hospitalized, with the most recent case confirmed on November 13. Investigators found that some stores in Oregon, Minnesota, and Arizona continued to sell the recalled formula, even though the company had already ordered a nationwide recall. Independent laboratory tests confirmed that Clostridium botulinum was present in certain samples of the formula. This bacterium can produce harmful toxins that are especially dangerous for infants younger than one year. Health experts described the situation as a serious public health concern and noted that the failure to remove recalled products increased the risk of additional cases.

The U.S. Food and Drug Administration conducted inspections at ByHeart manufacturing facilities in Iowa and Oregon to identify how the contamination occurred. Health officials urged households to stop using all ByHeart formula and to keep recalled cans for possible testing if symptoms appear. California’s Infant Botulism Treatment and Prevention Program opened a new public hotline after receiving a high number of calls from concerned caregivers. Officials advised that symptoms such as weak crying, constipation, and difficulty feeding require immediate medical attention. The situation highlighted the need for stronger recall enforcement, clearer communication, and improved oversight to prevent further incidents during this ongoing investigation.
