Washington pushes for comprehensive action to curb chemical contamination in infant formula

Legislation in the US aims to enforce stricter regulations on pesticides, heavy metals, and other contaminants in infant formula, amid rising concerns over health risks for babies and the need for systemic reform.

A new push in Washington is seeking tougher federal action to keep pesticides and other toxic chemicals out of infant formula, as concern grows over the range of contaminants that can reach products meant for babies. Beyond Pesticides said the issue cannot be solved by focusing on one substance at a time, pointing to a 2026 review in Environmental Toxicology and Pharmacology that found pesticide residues can appear alongside heavy metals, persistent pollutants, mycotoxins and chemicals from packaging in the same product.

The review examined 26 studies published over five decades and found that 22 reported pesticide residues in infant formula, including organochlorines, organophosphates, pyrethroids, neonicotinoids and herbicides. The authors said contamination is often tied to the wider supply chain, from farming and manufacturing to storage and packaging, which they argued supports broader regulation rather than piecemeal fixes.

Congress is now weighing four bills on infant formula safety. Two focus on microbial contamination, while a separate measure sponsored by Tom Barrett would direct the Department of Health and Human Services to study arsenic, cadmium, mercury and lead and then set standards for those heavy metals. The most far-reaching proposal, backed by Brian Mast, would require the department to set maximum levels for contaminants and to consider low-dose effects on infant brain development as well as whether a contaminant builds up in the body.

That debate comes as the Food and Drug Administration has stepped up its own testing. In April, the agency said it had completed what it described as its largest ever examination of chemical contaminants in infant formula sold in the United States, looking for substances including lead, mercury, cadmium, arsenic, PFAS and pesticides. The agency said most products met safety standards, but it also stressed that even small exposures matter for newborns. In July, the FDA followed up with a warning to manufacturers and suppliers to tighten oversight after a supply-chain contamination incident involving cereulide toxin in arachidonic acid oil used in formula.

The wider policy backdrop also includes growing support for cleaner agricultural systems. Research cited by Beyond Pesticides points to organic farming as a way to reduce pollution, protect biodiversity and improve public health. Studies in Frontiers in Sustainable Food Systems and Nature Sustainability found that organic management can strengthen soil health, increase carbon retention and reduce reliance on synthetic inputs, while researchers at Prairie View A&M University said the outlook for U.S. organic fruit and vegetables remains encouraging, helped by rising consumer demand and government support.
