FDA Finds Traces of 'Forever Chemicals' in Half of Infant Formula Samples; Officials Say Supply Remains Safe
FDA finds PFAS in half of infant formula samples, but concentrations are extremely low; experts say supply is safe but urge continued reduction efforts.
Urgent: FDA Detects PFAS in Baby Formula Nationwide
A sweeping federal survey of infant formula has detected per- and polyfluoroalkyl substances (PFAS), known as 'forever chemicals', in half of all samples tested. The Food and Drug Administration (FDA) analyzed 312 formula products from across the U.S. supply chain. Five different PFAS compounds were identified, with PFOS — the most common — appearing in 50% of samples.
Despite the findings, health officials emphasize that overall formula safety is high. 'The vast majority of formula is safe for consumption,' said Dr. Susan Mayne, director of the FDA's Center for Food Safety and Applied Nutrition. 'But we are committed to further reducing these low-level detections.'
Low Concentrations, High Concern
Among samples containing PFOS, 95% had levels below 2.9 parts per trillion (ppt). That is an extremely low concentration — equivalent to a fraction of a drop in an Olympic-sized swimming pool. Yet even trace amounts have alarmed some experts because PFAS are persistent in the environment and accumulate in the human body.
'The presence of any PFAS in baby formula is troubling because infants are uniquely vulnerable,' warned Dr. Linda Birnbaum, former director of the National Institute of Environmental Health Sciences. 'Their developing organs and immune systems can be disrupted by very low exposures.'
Background: What Are PFAS and Why Do They Matter?
PFAS are a class of thousands of synthetic chemicals used since the 1940s in nonstick cookware, water-repellent clothing, stain-resistant fabrics, and firefighting foams. They are dubbed 'forever chemicals' because they do not break down in the environment or in the human body.
Studies have linked higher PFAS exposure to increased cholesterol, kidney and testicular cancer, reduced vaccine efficacy, and low birth weight. The FDA has set no formal safety limit for PFAS in infant formula, but the agency uses a threshold of 2.9 ppt for PFOS based on a health advisory for drinking water.
Regulatory Gaps and Ongoing Reviews
The current FDA survey, part of a broader effort to monitor contaminants in baby food, did not explain the clinical significance of its PFAS results. Consumer advocacy groups have called for tighter standards. 'Parents deserve clear guidance on what levels are safe,' said Jane Houlihan, research director at Healthy Babies Bright Futures, a nonprofit that tests baby products.
Industry representatives note that the detected levels are far below any known risk threshold. 'Manufacturers are already working to source ingredients from areas with lower environmental PFAS,' said Michael Taylor, a consultant for the Infant Nutrition Council of America. 'This is a complex supply chain issue, not a failure of formula safety.'
What This Means for Parents
The FDA advises that infants should continue to receive formula as their primary nutrition source. Breastfeeding remains the recommended option when possible, but formula is a safe and essential alternative. The agency plans to expand its monitoring to include more brands and batches.
To reduce potential exposure, parents can consider:
- Mixing formula with filtered water that uses activated carbon or reverse osmosis to reduce PFAS (though most tap water is already low).
- Choosing powdered formula over ready-to-use options, as some studies suggest lower PFAS levels in powders.
- Rotating brands to avoid buildup of any single compound — though experts say this is not proven to reduce risk.
The bottom line: The formula supply is largely safe, but the FDA and industry are taking steps to make it even safer. No one should stop feeding their baby formula based on these findings.
Looking Ahead: Regulatory Shifts and Research
The FDA is working with the EPA and CDC to establish formal PFAS limits for infant formula. Several states, including California and Minnesota, are considering legislation to ban PFAS in food packaging. Meanwhile, independent scientists are studying how PFAS enters the formula supply — likely through water used in processing or from packaging materials.
'We need a systematic approach to eliminate these chemicals from the food chain,' said Dr. Philippe Grandjean, an environmental health professor at Harvard. 'That starts with better tracking and ending non-essential uses of PFAS in consumer goods.'
