An infant formula recall has been issued after testing found bacteria capable of producing a nerve toxin in products distributed nationwide under the ByHeart brand.
The California Department of Public Health said on November 8 that, during product testing, bacteria that can produce the neurotoxin botulinum were detected in ByHeart infant formula sold across the country.
The recall covers ByHeart Whole Nutrition Infant Formula products with production codes 251261P2 and 251131P2, with a use-by date through December 2026.
Health authorities urged consumers who have the recalled infant formula to stop using it immediately. They added that additional testing is underway, and that state and federal health officials are jointly investigating the source of the contamination.
As a result of the contamination, at least 13 infants between 2 weeks and 5 months old in 10 states, including California, have been infected. No deaths have been reported so far.
According to the Centers for Disease Control and Prevention (CDC), infection cases have been reported since mid-August. Investigators found that the infants had all consumed the contaminated formula. All of them were hospitalized.
Infant botulism is a rare disease in the United States, with fewer than 200 cases reported each year. It is usually caused by bacteria in the intestines that produce toxin, and is linked to heat-resistant spores found in dust, soil, and water. Infection can also occur through contaminated honey, formula, or dust.
Infants under 12 months are at higher risk because their immune systems are still developing, and exposure can lead to severe paralysis. Key symptoms include reduced feeding, inability to hold up the head, drooping eyelids, lack of facial expression, a floppy or weak body, and difficulty swallowing or breathing. Health officials warn that symptoms can take several weeks to appear after exposure, so caregivers should monitor babies carefully.
Authorities advised all consumers who purchased the recalled infant formula to throw it away immediately or return it to the place of purchase. For more information, consumers can contact ByHeart customer service at 833-429-4327.
