Do US baby foods contain toxic heavy metals like arsenic and lead?

What's actually in it

The four heavy metals of concern in baby food are inorganic arsenic, lead, cadmium, and mercury. These are naturally present in soil and water, and crops absorb them as they grow. Baby food is made from concentrated ingredients, so the metals concentrate too.

Rice cereal has the most arsenic. Carrots, sweet potatoes, and other root vegetables accumulate cadmium. Fruit juices, especially apple and grape, carry lead. Seafood-based purees can carry mercury.

What the research says

A 2026 study on toxic elements in baby and young children's foods in the US found heavy metal contamination across product categories and found correlations with infant intake levels that raise health concerns.

This follows a high-profile 2021 US congressional investigation that found every major baby food brand tested had at least one product with arsenic, lead, cadmium, or mercury above the FDA's own recommended limits. The FDA has since set action levels for lead, but enforcement is still developing.

Feeding a variety of foods rather than relying heavily on any one product (especially rice cereal), making homemade purees with diverse ingredients, and choosing baby foods from brands that publish third-party heavy metal test results reduces cumulative exposure.
