A troubling outbreak of botulism linked to ByHeart infant formula has emerged, with dried milk powder from two companies potentially implicated in the situation. According to The Associated Press, the contaminated organic whole milk powder was produced by Organic West Milk Inc., a California-based company, and processed at a Dairy Farmers of America facility in Fallon, Nevada. As of now, the specific source of the contamination remains unclear.
The U.S. Food and Drug Administration (FDA) is currently investigating the outbreak, which has affected at least 51 babies across 19 states. Bill Van Ryn, an owner of Organic West Milk, revealed that a sample of his company’s milk powder tested positive for Clostridium botulinum, the bacteria responsible for botulism. However, he emphasized that this finding does not definitively link their product to the outbreak. “Nothing has been proven about our milk yet,” Van Ryn stated, suggesting that the contamination might have occurred during the process of converting milk into powder or subsequently into baby formula.
Organic West Milk, which sources milk from 55 farmers, has ceased sales of the powdered milk intended for baby products until further information is available regarding the source of the contamination.
Processing Details and Safety Protocols
The process of producing powdered milk involves pasteurizing liquid milk, concentrating it through evaporation, and then spraying it into a hot chamber to evaporate the water. This method leaves behind fine, dry milk particles. Dairy Farmers of America, a global dairy cooperative, processes approximately 1.5 million pounds of raw milk daily, resulting in the production of 250,000 pounds of whole milk powder. The organization confirmed that Organic West was the source of the milk sample that tested positive for botulism bacteria.
Despite passing all required tests, the processing facility is under scrutiny. In a statement, Dairy Farmers of America reiterated the responsibility of manufacturers to ensure the safety of their ingredients. On January 23, 2023, the FDA reported that the sample of organic whole milk powder collected from a supplier tested positive for botulism. Further testing revealed that this sample genetically matched bacteria found in ByHeart formula and in an unopened can linked to a sick infant.
The FDA has not publicly identified the supplier of the contaminated milk powder, and ByHeart has opted not to disclose the source of the milk powder samples that tested positive.
The Risks of Botulism in Infants
Botulism spores are typically present in the environment and can be found in many foods, often at low levels. According to Kristin Schill, a botulism specialist at the University of Wisconsin-Madison, healthy adults can consume Clostridium botulinum spores without falling ill. However, infants have underdeveloped digestive systems, which can allow the spores to germinate and produce toxins that may lead to paralysis or even death.
While spores can exist in milk, they are usually present in low concentrations. Pasteurization does not eliminate these bacteria entirely, and contamination can occur during processing. Historically, botulism spores have been found in infant formula, but this outbreak marks the first significant incident connected to the product. Although testing for botulism in infant formula is not mandatory, some manufacturers voluntarily conduct microbiological screenings to mitigate contamination risks.
As the investigation continues and the health of affected infants remains a priority, both Organic West and Dairy Farmers of America are cooperating with the FDA to determine the origins of the contamination. The FDA has urged consumers to be vigilant and has advised parents to monitor their babies for symptoms associated with botulism.
