The discovery is unsettling on its face: some baby formula brands can contain heavy metals like lead and arsenic, plus PFAS—often described as “forever chemicals.” Misryoum newsroom reported that a new investigation found potentially concerning levels of harmful contaminants in more than half of the formula products tested.
The nonprofit consumer advocacy group tested 49 powdered, liquid, and alternative protein and hypoallergenic formulas. In total, it found that more than half contained “potentially concerning levels” of contaminants. The concern isn’t just the presence of these substances, but the timing—infants are small, and their organ systems are still developing, meaning repeated exposure may be riskier.
In plain terms, contaminants can show up in ways parents don’t control. Misryoum newsroom reported that such exposure can also come through water, not only through ingredients. And even though the infant formula market is regulated, Misryoum newsroom noted that products don’t always “escape the effects of environmental pollution or process contamination.” There’s another part of the picture that matters: Misryoum newsroom reported that there are no limits on the levels of contaminants allowed in baby formulas in the U.S., and manufacturers aren’t required to test formulas for their presence.
Misryoum editorial desk noted that the investigation’s researchers framed their findings around risk assessment rather than an alarm bell. Consumer Reports said the formulas it tested “are safe to feed your baby,” even when low levels of contaminants were detected. The group said it used the most protective levels available to evaluate potential health risks—partly, it argued, to empower parents with information for a first food that is supposed to be foundational.
Still, the numbers aren’t trivial. Misryoum newsroom reported that in the investigation last year, lead and arsenic were found in a number of powdered infant formulas, prompting regulators to pledge increased oversight and testing. This time, the new report looked across liquid options too: among the 23 liquid baby formulas evaluated, eight were either free of heavy metals or contained low levels.
For many parents, the immediate question is what to do with this kind of information. Misryoum newsroom reported that the group encouraged families to talk with their child’s pediatrician about the formula they use and any concerns. It also advised parents not to make their own formula and to ensure they use clean water when mixing powdered formula. In the background of all this, there’s a practical reality: Misryoum newsroom noted that many safe, inexpensive options exist, including those available through subsidized programs like the Special Supplemental Nutrition Program for Women, Infants and Children.
The companies named in the report pushed back. Misryoum editorial team stated that Abbott and Mead Johnson challenged the findings by saying trace levels of heavy metals occur naturally in the environment and throughout the food supply. Abbott said its infant formulas are safe and comply with heavy metal regulations in the EU and Canada, and it cited meeting requirements set by the FDA and Canada’s federal health department as well. Mead Johnson said it employs “stringent testing protocols” and takes steps to reduce unintended materials in products, while meeting safety and quality standards set by U.S. and global regulatory bodies.
One moment that sticks with this story—though it’s small and totally human—is the routine of mixing formula: the faint smell of warmed water from a kettle, the quick clink of a scoop into a bottle before you shake it. It’s hard to imagine that routine paired with the idea of “potentially concerning levels.” Yet the report is now pushing the conversation from comfort to chemistry.
Misryoum newsroom reported that the Infant Nutrition Council of America responded by acknowledging the absence of FDA limits for heavy metals and said it looks forward to science-based limits that guide parents and healthcare providers. Meanwhile, a bill introduced by Sen. Gary Peters of Michigan last year—the Protect Infant Formula from Contamination Act—would require infant formula makers to notify the Food and Drug Administration within one business day of discovering contamination, misbranding or adulteration. Misryoum newsroom noted the measure passed the Senate Health, Education, Labor and Pensions Committee in January.
As for what comes next, regulators may have to decide how to translate “potentially concerning” results into rules that affect daily buying choices—without turning feeding into fear.
