Major infant formula manufacturers including Nestlé and Danone are facing widening recalls (archive) after contamination prompted investigations into two infant deaths in France and confirmed illnesses in multiple countries. The crisis centers on arachidonic acid oil (ARA), a lab-produced fatty acid added to formula in manufacturers’ attempts to artificially replicate breast milk.
French authorities are investigating whether two infant deaths are linked to Nestlé’s Guigoz brand formula, though no causal link has been established. Belgium and Brazil have confirmed cases of sick babies connected to Nestlé products. In the U.S., startup ByHeart’s “closest to breast milk” formula has been linked to 51 babies hospitalized with confirmed or suspected botulism dating back to December 2023.
The Biotech Gamble
As manufacturers push formula closer to breast milk by adding lab-produced fatty acids and synthetic compounds, they’re essentially conducting a massive experiment on vulnerable infants. The contaminated ARA oil at the center of Nestlé’s recall came from Cabio Biotech, a Chinese supplier that used fermentation technology to produce the synthetic ingredient.
Yale School of Public Health professor Rafael Perez-Escamilla warns that “human milk has thousands of bioactive compounds that interact, not just one or two,” cautioning against the unintended consequences of adding isolated lab-created nutrients. These biotech additives lengthen supply chains, introduce new contamination vectors, and shift risks to ingredient suppliers facing less regulatory scrutiny.
Marketing Over Safety
Dr. Bob Boyle of Imperial College London bluntly states that ingredients like ARA are optional add-ins primarily used to “prop up marketing claims” rather than provide proven benefits. “Industry self-regulation isn’t working very well and is having devastating consequences for a small number of babies,” he said.
The contamination involved cereulide toxin, which cannot be destroyed by heat or filtered out—meaning once present, entire production lines must be shut down and completely cleaned. The only “solution” was Nestlé’s recall of products across more than 60 countries.
The Biotech Milk Illusion
Shelley McGuire, director of the Margaret Ritchie School of Family and Consumer Sciences at the University of Idaho, puts it plainly: “We know a lot about what’s in human milk, but we’re just scratching the surface, so to think that any formula company is going to ever make something that’s like human milk is beyond what’s possible.”
Lars Bode, founding director of UC San Diego’s Human Milk Institute, questions the entire approach: “Why take that minimum risk if you can’t show me first that there is an effect that is beneficial for the baby?” There’s no proof these biotech additions actually help infants—yet they clearly introduce new contamination risks.
The incidents underscore a troubling reality: the more manufacturers try to engineer breast milk replacements with synthetic compounds and lab-produced ingredients, the more dangerous their products become. Real breast milk remains irreplaceable—and attempting to manufacture an industrial substitute may be creating more problems than it solves.
A Better Alternative: Real Human Milk
Rather than relying on lab-engineered formula with questionable additives, parents can access actual human breast milk through donor networks and milk banks. These community-based options provide what no factory can replicate: genuine human milk with its natural complexity of bioactive compounds.
Community milk-sharing networks like Eats on Feets and Human Milk 4 Human Babies connect mothers who have surplus milk with families who need it. These grassroots organizations operate commerce-free, helping thousands of babies receive real human milk instead of synthetic substitutes.
For those seeking more formalized options, the Human Milk Banking Association of North America operates 31 milk banks across the United States and Canada, while the European Milk Bank Association maintains nearly 300 locations across 30 European countries. Some European milk banks even provide unpasteurized donor milk, preserving the full spectrum of bioactive compounds including enzymes, antibodies, and beneficial bacteria.
Parents can also find breast milk through online platforms like Only The Breast and Breastfeeding Moms Unite, which facilitate connections between donors and families in need.

When corporate biotech solutions fail—as they repeatedly have—community-based sharing of real human milk offers a time-tested alternative that doesn’t require a supply chain of synthetic ingredients from fermentation facilities.
