FDA finds lingering PFAS contamination in popular infant formulas

Breaking: FDA detects PFAS in multiple infant formula brands

The U.S. Food and Drug Administration has identified per- and polyfluoroalkyl substances (PFAS) in several widely sold infant formula products, according to internal testing results released today. The chemicals, known as “forever chemicals,” were found at levels above the agency’s recommended safety threshold in three out of 10 tested batches.

“These findings are alarming because infants are especially vulnerable to toxic exposures,” said Dr. Linda G. Brown, a pediatric toxicologist at Boston Children’s Hospital. “Even low levels of PFAS can disrupt development and immune function.”

The FDA has not yet named the affected brands but says it is working with manufacturers to voluntarily recall the contaminated lots. The agency emphasizes that the overall risk to the infant population remains low.

Background: Forever chemicals persist in food supply

PFAS are a class of thousands of synthetic chemicals used for decades in nonstick cookware, waterproof clothing, and food packaging. They do not break down in the environment and accumulate in the human body over time.

Scientific studies have linked PFAS exposure to low birth weight, thyroid disease, reduced vaccine response, and certain cancers. The FDA has previously set advisory levels for PFAS in drinking water and some foods, but infant formula has not been routinely tested until now.

This contamination likely originates from manufacturing equipment, water used in production, or packaging materials, said Dr. Mark Sullivan, an environmental health scientist at the University of Michigan.

What This Means

Parents should not panic, but they can take steps to reduce exposure: choose powdered formula over ready-to-feed (which may have higher PFAS from packaging), and consider rotating between brands.

The FDA plans to expand its testing program and may set enforceable limits on PFAS in infant formula. Consumer advocacy groups are calling for mandatory labeling and a phase-out of PFAS in all food-contact materials.

“This is a wake-up call,” said Dr. Brown. “We need stricter regulations to protect our most vulnerable population.”
