FDA finds toxic ‘forever chemicals’ in baby formula but won’t set enforceable limits

WASHINGTON – The toxic “forever chemicals” known as PFAS were found in baby formula sold across the U.S., according to test data recently released by the Food and Drug Administration. 

The findings underscore an urgent and long-overdue need for legal limits on PFAS in food. One year ago, the Environmental Working Group urged the FDA to develop action levels for PFAS in food. 

Monitoring without action does not protect children. A PFAS action level would let the FDA take legal action to remove products from the market if they exceed that limit.

The FDA tested 312 infant formula samples from 16 brands for 30 PFAS compounds as part of its Operation Stork Speed initiative. Five PFAS compounds were detected. 

PFOS was most commonly detected, found in half of all samples at concentrations ranging from 0.51 to 6.0 parts per trillion. PFOS is one of the most toxic and well-studied PFAS and the Environmental Protection Agency says it’s likely to be carcinogenic to humans.

The FDA characterizes these levels as low and concludes the infant formula supply is safe.

“No safe level of PFAS exposure has been established, and that is especially true for infants,” said David Andrews, Ph.D., EWG chief science officer. 

“PFOS bioaccumulates in the body and it damages the immune system, including reducing the effectiveness of vaccines in babies and children. Detecting it in half of all formula samples and characterizing these findings as a proof of safety is not a conclusion the science supports,” said Andrews.

“Formula is the sole nutrition source for millions of American infants and toddlers. The FDA’s safety claim is not acceptable, given these detections of a known cancer-causing chemical. The agency must set enforceable PFAS action levels for food, as other nations already have done."

“Congress gave the FDA the authority to set limits on contaminants in infant formula. The agency has chosen not to use it,” said Scott Faber, senior vice president of government affairs at EWG. 

“Every day the FDA delays setting enforceable PFAS limits is another day American infants are exposed to toxic PFAS with zero legal protection. That is a policy choice, and it is the wrong one,” he said.

Not just trace contamination

PFOS was phased out of U.S. manufacturing under pressure from the EPA after evidence emerged of significant health hazards. It was used in 3M’s Scotchgard and widely deployed in firefighting foam at military bases and airports, contaminating groundwater systems across the country. 

EWG’s PFAS contamination map documents PFOS in the drinking water supply of nearly half the nation’s water systems. 

The EPA regulates PFOS in drinking water at a maximum contaminant level of just 4 parts per trillion, set because of PFOS’s classification as a carcinogen. 

The FDA has established no equivalent limit for infant formula, so infants and toddlers may continue to be exposed to PFOS in food, as well as in tap water.

“Most of the formula samples the FDA tested were powdered, and most parents mix powdered formula with tap water,” said Tasha Stoiber, Ph.D., senior scientist at EWG. “Depending on where you live, your tap water may be contaminated with PFAS.

“That means babies could be getting a double dose – PFAS already present in the formula powder, and additional PFAS from the water used to prepare it. That compounding exposure is exactly why we need enforceable limits, not just monitoring,” she added.

The FDA findings closely mirror Consumer Reports’ 2025 investigation, which found PFAS in almost all of the 41 popular baby formula brands it tested, including Enfamil, Similac and Bobbie. 

Consumer Reports also identified PFOS as the most concerning compound detected. 

Two independent investigations, the same alarming result – and still no enforceable federal standard for PFAS in food.

Food may be the primary route of PFAS exposure

For millions of Americans, food – not drinking water – is the main route of PFAS exposure. These chemicals enter the food supply through multiple pathways federal regulators have failed to close.

“PFAS are clearly infiltrating our entire food system as a direct result of regulatory failure,” said Andrews. 

PFAS-containing pesticides are being applied to crops. Biosolids contaminated with PFAS are being spread on farm fields. Contaminated water is being sprayed on food crops. Every one of these pathways is preventable, and every one of them remains legal,” said Andrews.

“We need to ban all nonessential uses of PFAS, starting with these agricultural applications, before the contamination gets any worse,” he added.

Stakes are highest for the most vulnerable

PFAS exposure, with its health stakes, begins before birth. 

PFAS are toxic at extremely low levels. They are known as forever chemicals because once released into the environment, they do not break down and can build up in the body. The Centers for Disease Control and Prevention has detected PFAS in the blood of 99% of Americans, including newborn babies

PFAS readily cross the placenta and have been detected in umbilical cord blood, confirming that the developing fetus faces direct prenatal exposure. 

When PFAS are detected in the infant formula that millions of American babies depend on as their sole source of nutrition, the exposure does not begin at the first feeding. For many infants, it has already been accumulating for months.

A recent study also links prenatal PFAS exposure to premature birth, low birth weight and infant mortality. The full range of documented harms extends further still: thyroid disruption, harm to the male reproductive system, pregnancy-induced high blood pressure, reduced fertility and shorter duration of breastfeeding. 

Very low doses of PFAS have been linked to suppression of the immune system. Studies show exposure to PFAS can also increase the risk of cancer, harm fetal development and reduce vaccine effectiveness

The impact on infants and toddlers is especially pronounced. “Babies are not small adults when it comes to chemical exposure – they are categorically more vulnerable,” said Stoiber. 

“Babies’ bodies are smaller, their organs are still developing, and their immune systems are not yet fully formed. When PFAS accumulate in an infant’s body, the proportional impact is far greater than it would be in an adult exposed to the same amount.

“Parents are often limited in the type of formula that is available to them and the FDA’s testing did not disclose the brand names tested. The FDA must act to protect all children,” she added.

“The administration says it wants to make America healthy again,” said Faber. “Here is a straightforward way to start: Set enforceable limits on PFAS in baby formula today. 

“The science is clear, the authority exists and the harm has been documented. American families cannot wait any longer for the federal government to do its job,” he added.

What parents can do right now

No parent should have to navigate this alone. Until the FDA establishes enforceable PFAS standards in infant formula, here are practical steps to reduce your baby’s exposure:

  • Use filtered water when preparing powdered formula. A reverse osmosis system provides the most effective PFAS filtration. Countertop pitcher filters have also shown meaningful effectiveness in EWG testing. 
  • Check EWG’s PFAS contamination map to see whether your local water supply has documented PFOS or other PFAS contamination.
  • Make your voice heard. Contact the FDA and your elected representatives and demand enforceable PFAS limits in infant formula. The FDA’s Operation Stork Speed is an ongoing testing program. Sustained public pressure from parents is one of the most effective ways to accelerate the regulatory action.
