US Infant Botulism Outbreak: 37 Cases Linked to ByHeart Formula Recall
Infant Botulism Outbreak: 37 Cases in Formula Recall

Nationwide Health Alert as Infant Botulism Cases Rise

Health experts across the United States are raising urgent concerns as hospitalisations of infants continue to climb. The alarming trend has been directly connected to contaminated baby formula, prompting a major nationwide product recall.

ByHeart's Voluntary Recall and Ongoing Investigation

ByHeart, a baby formula manufacturer based in Reading, Pennsylvania, has issued a voluntary recall for all of its infant formula products. This decisive action follows notification from the US Food and Drug Administration (FDA) regarding a broader investigation into a recent outbreak of infant botulism. This rare but serious illness occurs when bacteria in a baby's gut produce a toxin that leads to significant muscle weakness.

The investigation gained momentum after the California Department of Public Health tested a can of ByHeart powdered formula that had been fed to an infant who later contracted botulism. Preliminary results from these tests suggested the presence of the bacteria responsible for producing the botulinum toxin.

The FDA first informed ByHeart about the reported cases on November 7, with the initial illnesses appearing as far back as August. Since the last official update on November 20, six new cases have been added to the investigation. This brings the total number of infants believed to have been sickened by the formula to 37. Experts involved fear this number may continue to grow.

Widespread Impact and Legal Action

The consequences of this outbreak are far-reaching. To date, 15 infants have been hospitalised after reportedly consuming the ByHeart formula. The cases have been reported across 17 different states, including Arizona, California, Illinois, Michigan, Pennsylvania, Texas, and Washington.

Legal representatives are now involved. Attorneys from Marler Clark, The Food Safety Law Firm, along with regional co-counsel, are representing many of the affected families. Lead attorney Bill Marler confirmed he has been retained by over a dozen families whose children are part of this outbreak and expects more cases to be identified.

For the 36 cases with available information, the onset of illnesses occurred on dates ranging from August 9 through November 19. Fortunately, no deaths have been reported in connection with this outbreak.

Understanding the Danger of Infant Botulism

Infant botulism poses a severe threat to babies because the toxin can paralyse the muscles required for breathing, which can lead to respiratory failure. It is a rare condition, typically affecting babies under one year old. In the US, there are usually between 200 to 300 cases of botulism reported annually, with about two-thirds being the infant form.

The illness occurs when spores of the bacterium Clostridium botulinum enter an infant's intestines, where they grow and produce a potent natural toxin. Symptoms parents should watch for include:

  • Constipation
  • Poor feeding
  • Drooping eyelids
  • Weak cry
  • Low muscle tone
  • Respiratory difficulty

The primary treatment is an antitoxin called Botulism Immune Globulin Intravenous (BIG-IV), accompanied by extensive supportive care in a hospital. Recovery can be a lengthy process, sometimes taking months or even years, as the body must grow new nerve terminals disabled by the toxin.

Official Guidance for Parents and Consumers

Despite the recall, ByHeart has highlighted that this action is being taken out of an abundance of caution. The company notes that the FDA has not yet established a direct causal link between its infant formula and the reported botulism cases. A company representative stated, 'No ByHeart product has tested positive for any contaminants'.

Nevertheless, the FDA has issued a 'do not use' warning for all ByHeart infant formula products. The voluntary recall applies to all lot numbers and all sizes of cans and single-serve packets.

The Centers for Disease Control and Prevention (CDC) offers specific advice for consumers:

  • Record the lot number and 'best by' date of any recalled formula if possible.
  • Do not immediately discard leftover powdered formula. Store it safely for at least one month in case health officials need to test it if symptoms develop.
  • If no symptoms occur after a month, the formula should then be discarded.
  • Thoroughly clean and disinfect any items or surfaces that contacted the formula using hot, soapy water or a dishwasher.

Parents should contact their healthcare provider immediately if their infant shows any symptoms consistent with botulism. Consumers who have purchased the affected products are advised to stop using them immediately. ByHeart has committed to replacing any recalled cans at no cost, and businesses have been instructed to stop sales and sanitise relevant surfaces.
