New federal testing data covering hundreds of infant formula products gives parents the clearest picture to date of what’s actually in the formula their babies drink — and the news is largely reassuring.

On April 29, 2026, the agency released the findings of a sweeping safety review that examined more than 300 individual formula products spanning 16 brands, covering powdered, ready-to-feed, and concentrated liquid varieties. Conducted under the agency’s broader Closer to Zero initiative, a federal program designed to minimize children’s dietary exposure to potentially harmful substances, the testing generated over 120,000 data points across an extensive list of chemical contaminants, including heavy metals, pesticides, PFAS compounds, and phthalates.

The scale of this effort was unlike anything the agency had undertaken before. Researchers screened for lead, mercury, cadmium, and arsenic, as well as widely used agricultural chemicals like glyphosate and glufosinate. They also tested for per- and polyfluoroalkyl substances, commonly known as PFAS or “forever chemicals,” and phthalates, a class of plasticizers found in many everyday consumer products. The goal was to give parents the clearest and most complete picture yet of what is actually in the formula their babies drink every day.

The results were broadly reassuring. Across nearly every category tested, the overwhelming majority of products came back with either undetectable levels or amounts too small to raise safety concerns. Heavy metal concentrations across all samples fell well within acceptable federal safety thresholds. Agricultural chemical residues were essentially absent, detected in just one out of every hundred samples. The picture for PFAS was similarly encouraging, with the most commonly assessed compounds absent from every single sample tested.

Regulators were also transparent about the fact that a small number of products showed readings that warranted follow-up with manufacturers. The FDA has committed to continuing its surveillance, expanding the scope of contaminants screened, and pushing formula makers toward the lowest possible contamination levels over time. Families can track ongoing formula testing results directly on the FDA’s website as new data becomes available.

For parents of newborns and infants who rely on formula, this data offers meaningful reassurance. The U.S. formula supply is being monitored more rigorously than ever before, and the results so far support confidence in what is on store shelves. That said, no testing program eliminates every question a parent might have. If you have concerns about a specific formula your baby is using, or if your child has a known sensitivity or health condition, the best next step is always a direct conversation with your pediatrician.
