Out of 312 infant formula samples pulled from store shelves across the country, the overwhelming majority contained either no detectable contamination or trace amounts so small they fell well within federal safety limits. That is the central finding of the largest testing effort ever conducted on U.S. infant formula, released by the Food and Drug Administration in May 2026 after a survey spanning fiscal years 2023 through 2025.
The FDA screened products from 16 brands across all three formats sold to consumers: 278 powdered formulas, 11 concentrated liquids, and 23 ready-to-feed options. The agency has not publicly identified which brands were included or specified whether any organic formulas were part of the sample set. Each sample was tested for toxic elements including arsenic, lead, cadmium, and mercury, plus 30 PFAS compounds, 318 pesticides, 21 phthalates, and one non-phthalate plasticizer. The effort generated more than 120,000 individual data points, all of which the agency has made available through its formula testing results page.
For parents who have spent the past several years navigating formula shortages, recalls, and alarming headlines about heavy metals in baby food, the results offer something that has been in short supply: concrete, large-scale federal data focused specifically on infant formula.
What the testing found
The FDA used inductively coupled plasma mass spectrometry to measure toxic element concentrations at the individual sample level, with results expressed in units that reflect formula as prepared for feeding, not as dry powder. When the agency compared its heavy-metal findings against Environmental Protection Agency drinking-water standards for lead, mercury, cadmium, and arsenic, the formula samples cleared those benchmarks. A summary of key findings published alongside the full dataset confirmed the result in plain language: contaminant levels across the tested supply posed no safety concern at the concentrations detected.
That conclusion carries a nuance worth understanding. “Below harmful levels” does not mean “zero.” Modern lab equipment can detect contaminants at extraordinarily low concentrations, and the FDA’s own tables show that some samples contained measurable traces of metals and other chemicals. The agency’s safety determination rests on dose-response toxicology: at the levels measured, and given how much formula infants typically consume, regulators judged that exposure would stay within health-protective margins. Parents accustomed to headlines that treat any detectable amount of a toxin as dangerous may find that framing unsatisfying, but it reflects how food-safety science works in practice.
It is also worth noting what the data does not yet show at the granular level. While sample-by-sample results for toxic elements are publicly available, the findings for PFAS, pesticides, and phthalates are presented only in aggregated form. Researchers and advocacy groups who want to compare specific brands or product lots on those analytes cannot yet do so. The FDA has not indicated whether it plans to release that level of detail.
Why this testing happened now
The survey is one piece of Operation Stork Speed, an initiative from the Department of Health and Human Services and the FDA aimed at expanding access to safe infant formula. According to the agency’s official announcement, the program also includes commitments to review formula nutrient standards, increase microbiological and spore-former testing, continue a personal importation policy for certain foreign formulas, and improve public transparency around formula oversight. Operation Stork Speed program materials describe those nutrient standards as not having been updated since 1998, though the agency has not specified in which document or regulatory filing that date originates.
The broader backdrop matters. In 2022, a contamination crisis at Abbott Nutrition’s Sturgis, Michigan, plant led to a massive recall and months of formula shortages that left families scrambling. That episode, combined with a February 2021 report from the House Subcommittee on Economic and Consumer Policy titled “Baby Foods Are Tainted with Dangerous Levels of Arsenic, Lead, Cadmium, and Mercury,” which found elevated heavy metals in several categories of commercial baby food, intensified public pressure on the FDA to prove it was actively monitoring what goes into products consumed by the country’s most vulnerable population. That congressional report focused primarily on baby cereals, snack puffs, teething products, and purees rather than infant formula, which makes direct comparison with the FDA’s 2023-2025 formula survey difficult. The two efforts tested different product categories, used different methodologies, and applied different risk thresholds.
The FDA’s Closer to Zero initiative, launched before Operation Stork Speed, provides the regulatory scaffolding. That program sets interim reference levels and action levels for arsenic, lead, cadmium, and mercury in foods marketed to babies and young children, using an iterative cycle of research, industry guidance, and enforcement to push contamination downward over time. The infant formula results now feed directly into that framework, giving regulators a baseline from which to measure future progress and decide whether tighter limits are warranted.
What the data does not answer
Several gaps remain. The FDA has not identified which of the 16 brands were tested or broken results down by brand name, so parents cannot use this data to comparison-shop. The agency also has not published equivalent testing from earlier periods, which means there is no way to determine whether contaminant levels have improved, held steady, or shifted since the 2022 supply disruptions. The results are best understood as a detailed snapshot of the current marketplace, not a trend line.
No formula manufacturer has publicly responded to the findings with its own data or commitments. The FDA’s announcement did not include statements from any of the companies whose products were tested or indicate whether brands were consulted before publication. That silence leaves open the question of whether producers plan voluntary reformulations, tighter ingredient sourcing, or process changes in response to even the low-level detections that appeared in some samples.
There is also an open question about the EPA drinking-water comparison the FDA used as a benchmark. Those thresholds were designed for municipal water systems, not specifically for infant feeding. While the comparison provides a useful reference point, some toxicologists and child-health advocates have argued that standards for products consumed exclusively by infants should be more stringent than those applied to the general water supply. The FDA’s Closer to Zero program is, in theory, working toward infant-specific action levels, but that process remains ongoing.
How caregivers can engage with the FDA on formula safety
For caregivers, the practical takeaway is straightforward: currently available formulas across powder, concentrated liquid, and ready-to-feed formats met federal safety expectations for every contaminant category the FDA measured. That finding covers the broadest set of analytes ever tested in a single U.S. formula survey.
Parents who have concerns about a specific product can report safety issues through the HHS safety reporting portal, which routes complaints to federal regulators for review. The FDA has also opened channels for public input on its formula oversight and its broader efforts to reduce toxic element exposure in early childhood diets. For families who want a voice in what comes next rather than waiting for the next round of headlines, those are the most direct paths available.
