Preliminary tests showed that ByHeart baby formula contained the type of bacteria that produces the toxin linked to a botulism outbreak, California health officials said.
The outbreak has sickened at least 13 infants in 10 states. No deaths have been reported.
“Consumers in possession of this product should stop using it immediately,” the California Department of Public Health said in a statement late Saturday.
More tests of ByHeart Whole Nutrition Infant Formula are pending as state and federal health officials investigate the outbreak that started in mid-August. The New York-based company this weekend recalled two lots of the powdered product.
Here’s what to know about the outbreak and infant botulism.
Infant botulism outbreak
The outbreak of infant botulism has sickened babies aged 2 weeks to 5 months since mid-August. All were hospitalized after consuming ByHeart powdered formula, according to the U.S. Centers for Disease Control and Prevention.
The cases occurred in Arizona, California, Illinois, Minnesota, New Jersey, Oregon, Pennsylvania, Rhode Island, Texas and Washington.
ByHeart officials agreed to recall two lots of the company’s Whole Nutrition Infant Formula, according to the U.S. Food and Drug Administration. The formula has a best-by date of December 2026.
California health officials tested a can of the powdered formula that was fed to a baby who fell ill. The results “suggest the presence” of the type of bacteria that produces the botulism toxin confirmed in other cases. It can take several days to confirm the results.
ByHeart officials said that “more testing is needed” to know whether the type of bacteria that causes botulism is present. It comes from a large family of bacteria, many of which are found naturally in the environment and don’t cause illness, the company said.
“We take this very seriously,” it said in a statement Sunday.
The FDA is investigating reports of 83 cases of infant botulism reported since August including the cases linked to ByHeart baby formula.
