Overview
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in consumer products for their resistance to heat, water, and oil. Unfortunately, these “forever chemicals” can migrate into food and beverages, including infant formula. Recent news highlights that despite regulatory action, PFAS still persists in some infant formulas. This guide is designed to help parents and caregivers understand the issue, identify at-risk products, and take practical steps to reduce exposure. We’ll also touch on the FDA’s recent leadership change, which may influence future PFAS regulation.
Prerequisites
- Basic knowledge of infant formula types (powder, liquid concentrate, ready-to-feed).
- Access to product labels – either from the store or manufacturer websites.
- Willingness to read about FDA guidelines – we’ll summarize the key points.
Step-by-Step Instructions
1. Understand How PFAS Gets Into Formula
PFAS can enter the supply chain through contaminated water used in production, packaging materials (e.g., plastic containers with PFAS-based coatings), or from ingredients grown in polluted soil. The chemical is persistent and can bioaccumulate, raising concerns about long-term health effects in infants.
2. Check for Recent Recalls or Consumer Alerts
- Visit the FDA recall page regularly.
- Search for “PFAS” or “PFOS” (a common PFAS compound) in the recall database.
- Subscribe to the FDA’s Morning Rounds newsletter for daily health updates; they frequently cover emerging contaminant news.
Note: The FDA recently named an interim successor for Vinay Prasad, a key official involved in food safety oversight. This transition may affect the speed and rigor of PFAS enforcement, so staying informed is crucial.
3. Identify PFAS-Free Labeling and Certifications
Look for formulas that advertise:
- “No PFAS,” “PFAS-free,” or “tested for PFAS.”
- Organic certification (though it’s not a guarantee, organic standards often restrict PFAS in packaging).
- Glass containers instead of plastic (PFAS is often in plastic linings).
4. Choose Lower-Risk Formula Types
- Powdered formulas typically have lower PFAS levels because they use less liquid during production.
- Ready-to-feed liquid may have higher risk due to packaging contact.
- Store brands are not inherently riskier, but you must verify their sourcing.
5. Test Your Water If You Use Concentrate
PFAS contamination often comes from tap water used to reconstitute formula. Order a PFAS test kit from a certified lab (cost ~$200–500). If PFAS is detected, use bottled water labeled as “purified” or “distilled” – but check that the water brand tests for PFAS (many do).
6. Contact Manufacturers Directly
Call or email the formula company’s consumer hotline. Ask:
- “Do you test your products for PFAS?”
If yes, request the test results. - “What steps do you take to ensure your water and packaging are PFAS-free?”
Document the answers and date of contact.
7. Monitor Advocacy and Regulatory Changes
- The FDA has set interim reference levels (iRLs) for PFAS in food. As of 2024, FDA has not banned PFAS in infant formula, but pressure is mounting.
- Nonprofits like Environmental Working Group (EWG) publish lists of tested baby products.
- Follow the FDA’s work on PFAS via their PFAS page.
Common Mistakes
Assuming “organic” means PFAS-free
Organic regulations limit synthetic pesticides and fertilizers but do not specifically ban PFAS in packaging. Some organic formulas have still tested positive for low levels.
Relying solely on boiling water
Boiling does not remove PFAS; in fact, it can concentrate them if the water evaporates. Use filtration systems certified to reduce PFAS (e.g., activated carbon, reverse osmosis).
Ignoring the “interim” nature of FDA guidelines
The FDA’s reference levels are not legally binding. Manufacturers are not required to test for PFAS, and no action level has been set specifically for infant formula. Parents must stay vigilant.
Thinking glass jars are always safe
Glass jars can still have metal lids with PFAS-coated gaskets. Check if the lid lining is BPA- and PFAS-free.
Summary
PFAS contamination in infant formula remains a concern due to its persistence in water and packaging. Parents can reduce risk by choosing powders, verifying water quality, and contacting manufacturers. Recent leadership changes at the FDA (including the appointment of Vinay Prasad’s interim successor) may affect future regulation, so staying informed through reliable sources like FDA alerts and newsletters is key. By following the steps above, you can make more confident choices for your baby’s nutrition.
