Infant Botulism Outbreak Linked to Infant Formula

The Centers for Disease Control and Prevention (CDC), public health officials in several states, the California Department of Public Health Infant Botulism Treatment and Prevention Program, and the U.S. Food and Drug Administration (FDA), are investigating a multistate outbreak of infant botulism linked to infant formula.

Parents and caregivers have reported feeding infants in this outbreak different lots of ByHeart infant formula. The company has recalled all ByHeart Whole Nutrition infant formula products.

Consumers are being advised to not use any ByHeart Whole Nutrition infant formula.

Infant botulism happens when a baby swallows Clostridium botulinum spores that grow in the gut and make toxin. Infant botulism often starts with constipation but is usually first noticed as difficulty feeding (sucking and swallowing), a weak and altered cry and lack of head control.

RDNs can provide guidance to families as they seek alternatives for ByHeart products.

The Academy recommends the following:

• If your infant or child refuses to drink a new formula after several tries, contact your physician or RDN for additional guidance.
• Follow the manufacturer's label when preparing infant formula and do not add more water to "stretch" the amount of formula per serving.
• Do not purchase infant formula or breast milk from unknown sources or online because they are not safe and may contain harmful ingredients.
• Purchasing pasteurized donor human breast milk from milk banks is an appropriate alternative for some infants, when available.
• Be aware of and follow expiration dates. Once expired, you can't guarantee the formula's quality or safety.
• Homemade infant formulas are not recommended and can lead to both short- and long-term health issues for infants and children.
• If possible, breastfeeding is a great option to meet your child's nutrition needs. Consult an RDN for more information on the benefits of breastfeeding.
• Monitor the amount of formula you have available. If you are having difficulty obtaining the appropriate formula for your child, contact your physician, RDN or another health care provider before supply is depleted; they can help you find a suitable formula for your child.
