Recent FDA testing of infant formula has sparked questions among parents about the presence of PFAS—also known as “forever chemicals.” While the agency’s survey of 312 samples found the U.S. formula supply to be largely safe, trace amounts of these synthetic compounds were detected. This Q&A unpacks the findings and offers practical insights for caregivers. Jump to the first question to learn more.
What exactly are PFAS, and why are they called “forever chemicals”?
PFAS (per- and polyfluoroalkyl substances) are a group of man-made chemicals used in products like nonstick cookware, stain-resistant fabrics, and firefighting foams. They are termed “forever chemicals” because they break down extremely slowly in the environment and can accumulate in the human body over time. This persistence means that even low-level exposure can lead to measurable concentrations in blood. The health effects linked to higher PFAS levels include elevated cholesterol, kidney and testicular cancer, and reduced vaccine effectiveness. For infants, who are more vulnerable to environmental contaminants, the presence of any PFAS in formula raises understandable concern—even at trace levels.
What did the FDA find in its testing of baby formula?
The Food and Drug Administration analyzed 312 samples of infant formula and detected five different types of PFAS. The most common chemical was PFOS (perfluorooctane sulfonate), which appeared in half of all samples. However, 95% of those PFOS-containing samples had less than 2.9 parts per trillion (ppt)—an extremely low concentration. The FDA did not provide a detailed explanation of what these PFAS levels mean for infants, leaving many parents to wonder about the potential risks. It is important to note that the test results indicate the overall formula supply is safe for consumption according to current standards.
Are the PFAS levels found in formula dangerous for my baby?
Current scientific evidence suggests that the PFAS concentrations measured by the FDA are well below thresholds known to cause harm. The majority of samples contained less than 2.9 ppt of PFOS, which is comparable to levels sometimes found in drinking water or food. While long-term, high-level exposure has been linked to health problems, the trace amounts in formula are not considered a cause for alarm by health officials. Experts emphasize that the benefits of infant formula—especially for babies who are not breastfed—far outweigh any theoretical risk from these minuscule chemical residues. Nonetheless, ongoing monitoring and efforts to reduce PFAS in the food supply are important public health priorities.
How do PFAS get into infant formula in the first place?
PFAS can enter infant formula through several pathways. One major route is contaminated water used in processing or as an ingredient. Additionally, the chemicals may leach from packaging materials, such as the lining of cans or plastic containers. Farmland used to grow ingredients like soy or corn can also be exposed to PFAS through sludge fertilizer or irrigation water. Because PFAS are so widespread in the environment, trace amounts are nearly impossible to eliminate completely. The FDA’s detection of these compounds does not necessarily indicate intentional contamination but rather reflects their ubiquity. Manufacturers and regulators are working to identify and reduce these sources to further lower exposure.
What steps can parents take to reduce PFAS exposure from formula?
While the FDA considers the formula supply safe, parents who want to minimize potential PFAS intake can consider several practical steps. First, prepare formula using filtered water—a water filter certified to reduce PFAS can help, though boiling water does not remove these chemicals. Second, choose powdered formula over ready-to-feed liquid versions, as packaging may be a source of PFAS contamination. Third, avoid storing prepared formula in nonstick cookware or plastic containers. Finally, if possible, incorporate some breastfeeding, as breast milk—while not immune to environmental contaminants—typically has lower PFAS levels than formula. These measures can provide extra peace of mind, but the most important factor is ensuring your baby gets adequate nutrition.
Is the U.S. infant formula supply overall safe?
Yes, according to the FDA’s comprehensive survey, the U.S. infant formula supply is largely safe for consumption. The agency tested 312 samples for a wide range of contaminants, and the PFAS detections were at trace levels—far below any established health concern. The presence of PFAS does not negate the safety or nutritional value of formula products. Experts stress that parents should continue to use formula as directed by pediatricians, especially for infants who depend on it as their primary food source. The FDA, along with manufacturers, is actively pursuing ways to further reduce environmental pollutants in formula, but no immediate changes are needed in how families feed their babies.
What is being done to reduce PFAS in baby formula going forward?
Federal agencies and formula manufacturers are taking steps to lower PFAS contamination. The FDA is conducting ongoing surveys to monitor levels and identify sources, while also working with industry to improve manufacturing practices and ingredient sourcing. Some companies are switching to PFAS-free packaging and using filtration systems for water. Additionally, environmental regulations that limit PFAS discharge into water and air will help reduce overall contamination. Long-term, the goal is to bring levels as close to zero as possible. Parents can expect more transparent labeling and updated guidance as science evolves. For now, the consensus remains that current levels do not pose a health risk, but vigilance and improvement continue.
