FDA Infant Formula Safety 2026: What the Largest-Ever Test Results Mean for Parents

By Roa — Roasted Almond North America · April 29, 2026 · Reading time: ~7 minutes

On April 28, 2026, the U.S. Food and Drug Administration (FDA) released the results of its largest infant formula safety study to date. For most parents, the headline is reassuring — but a closer look shows the picture is more nuanced than a single press release suggests.

The short answer: U.S. infant formula is broadly safe, but not “case closed”

According to FDA infant formula safety testing released this week, the overwhelming majority of U.S. infant formula samples contained undetectable or very low levels of contaminants. The FDA’s own conclusion is that the U.S. infant formula supply is safe for the babies who depend on it.

That said, several independent experts and consumer-protection groups argue the new data does not fully resolve concerns about so-called “forever chemicals” (PFAS), phthalates, and how quickly contaminated products are pulled from store shelves when something does go wrong. So the practical takeaway for parents is:

Why the FDA says the formula supply is safe

The new FDA infant formula safety report is the result of an initiative the agency calls Operation Stork Speed, launched jointly by the Department of Health and Human Services and the FDA in March 2025 to modernize oversight of the U.S. infant formula supply.

As part of this effort, the FDA tested more than 300 infant formula samples representative of products sold at U.S. retail — including powders, ready-to-feed liquids, and concentrated liquids — and generated more than 120,000 individual data points. Samples were screened for:

• Heavy metals: lead, mercury, cadmium, and arsenic
• Pesticides, including glyphosate and glufosinate
• Per- and polyfluoroalkyl substances (PFAS)
• Phthalates (chemicals used as plasticizers)

The agency reports that across this set, an overwhelming majority of samples had undetectable or very low contaminant levels. You can read the FDA’s full announcement on the official FDA news page.

The FDA also says it will continue follow-up testing, share additional results publicly, and convene a roundtable in May with the chief executives of major infant formula companies to discuss further modernization of oversight.

Where outside experts still have concerns

The FDA describes the testing results as encouraging. Independent reviewers are more measured. A few of the friction points worth understanding:

1. PFAS and phthalates have no formal U.S. limits in formula

Although FDA testing detected only low levels, the United States does not currently have established maximum allowable levels for environmental contaminants such as PFAS or phthalates specifically in infant formula — a gap that an FDA expert panel itself flagged in its June 2025 published proceedings. Other regions, including the EU and Canada, have set such limits, leaving U.S. parents and pediatricians with less of a reference point for what counts as “low enough.”

2. Independent testing has found contaminants too

In separate testing released in March 2026, Consumer Reports analyzed 49 infant formula products — including powders, ready-to-feed liquids, and alternative-protein options — and reported finding contaminants at potentially concerning levels in roughly half of them, including lead, arsenic, BPA, acrylamide, and PFAS. Methodologies differ from FDA’s, and infant formula manufacturers have pushed back on some interpretations, but the broader point is that independent and regulatory results don’t always line up neatly.

3. Recalls don’t always clear shelves quickly

The most recent reminder is the ByHeart Whole Nutrition infant formula recall in November 2025, linked to a multistate outbreak of infant botulism. Following that recall, the FDA reported that recalled product was still being found on store shelves — in one case, for more than three weeks across more than 175 locations in 36 states — prompting warning letters to several major retailers.

This came on top of historical concerns about FDA’s response speed during the 2022 Cronobacter contamination at an Abbott formula plant, which contributed to a nationwide formula shortage and is a key reason Operation Stork Speed exists in the first place.

Concrete examples: what parents have actually faced

Three recent episodes in North America help put the new FDA infant formula safety data in context:

Example 1 — ByHeart, late 2025. A multistate outbreak of infant botulism was linked to ByHeart Whole Nutrition Infant Formula. ByHeart issued a voluntary recall of two batches on November 8, 2025, then expanded it to all products on November 11, 2025. According to CDC, more than 50 infants across multiple states were ultimately included in the outbreak case definition, and FDA later identified Clostridium botulinum in both finished formula and a whole milk powder ingredient sample.

Example 2 — Consumer Reports testing, 2025–2026. Two rounds of independent lab testing reported finding lead, arsenic, PFAS, BPA, or acrylamide at potentially concerning levels in some products, including in specialty formulas marketed for sensitive infants.

Example 3 — The 2022 Abbott Cronobacter recall. Microbial contamination at a single major plant cascaded into a nationwide formula shortage and renewed scrutiny of FDA’s inspection and recall processes — the policy backdrop against which the current Operation Stork Speed initiative is being judged.

Together, these cases show two things at once: serious problems are rare relative to the volume of formula consumed every day in North America, but when they happen they tend to expose recurring weaknesses in how quickly the system responds.

Practical tips for parents and caregivers

Beyond the headlines, there are concrete, evidence-based steps parents in the U.S. and Canada can take to lower risk further. These are general practices and not a substitute for advice from your pediatrician, but they apply broadly:

Check for active recalls before buying or using

Before opening a new container, scan for active alerts on the FDA Recalls page (U.S.) or the Canadian recall portal. If a brand or batch is listed, do not use it — even if the product looks and smells normal.

Use filtered or low-contaminant water for powdered formula

Because PFAS and lead can also enter drinking water, the water you mix into powdered formula matters. A certified filter that targets lead and PFAS can meaningfully reduce overall exposure, particularly in older homes or areas with known water-quality concerns.

Follow preparation and storage guidance carefully

Most microbial risk in powdered formula is reduced by following label instructions: clean hands and surfaces, sanitized bottles, water at the temperature recommended by the manufacturer, and prompt refrigeration or disposal of unused prepared formula. The CDC and AAP both publish detailed prep guidance.

Consider breast milk where it works for your family

Major U.S. and Canadian health authorities, including the AAP and the Public Health Agency of Canada, continue to recommend breast milk as the first feeding option where it is available and feasible. That recommendation is unchanged by the new FDA testing — but it is also not a judgment of families who use formula for medical, logistical, or personal reasons.

Talk to your pediatrician about specialty formulas

If your baby uses a hypoallergenic, soy-based, or other specialty formula, talk with your pediatrician before switching brands in response to news coverage. Some independent test reports have flagged specialty products specifically, but switching abruptly without medical input can cause its own problems.

In summary

The 2026 FDA infant formula safety results are genuinely good news: the largest U.S. testing program of its kind found very low contaminant levels in the overwhelming majority of products on the shelf. At the same time, outside experts are right to point out that the U.S. still lacks formal limits for several relevant chemicals in formula, that independent labs sometimes report different findings, and that recalls have not always cleared store shelves as quickly as they should.

For parents, the practical posture is neither alarm nor complacency. Use a non-recalled formula from an established manufacturer, prepare it with clean hands and good water, keep an eye on official recall pages, and lean on your pediatrician for choices specific to your child. Most North American babies on formula are getting safe nutrition — and the regulatory system, imperfect as it is, is moving in the right direction.
