Heavy metals in baby food: what FDA Closer to Zero covers and what organic does not fix

FDA explains that arsenic, lead, cadmium and mercury occur in the environment naturally, as elements in the earth's crust, and from human activity. Levels in air, water and soil vary by place and by past pollution. Plants take the metals up the way they take up nutrients.

That is why the issue is not limited to one brand or one kind of farm. FDA says it is not possible to remove lead entirely from the environment or the food supply. Its goal is to push exposure as low as possible while keeping nutritious foods available.

Babies and young children are the priority because, in FDA's words, their smaller body sizes and metabolism make them more vulnerable to the harmful effects of these contaminants.

No, and this is the limit of the organic label that matters most on this page. USDA Organic rules cover how crops are grown and how food is processed. They are not a heavy metals standard, and the seal makes no claim about lead, arsenic, cadmium or mercury in the finished food.

The American Academy of Pediatrics (AAP) puts it plainly: organic baby foods may have lower levels of certain pesticides, but because heavy metals are found in the soil and can get into prepared foods from processing, organic foods often contain similar levels of heavy metals as non-organic foods.

A naming trap adds to the confusion. FDA notes that organic arsenic compounds are a chemical category, meaning arsenic bound with carbon, and have nothing to do with organic farming. Inorganic arsenic is the more harmful form, and it is the one FDA's limits target.

So when you compare products on our organic baby food page, read the organic seal as a statement about farming and pesticides. It is not a heavy metals claim.

Closer to Zero is FDA's program for lowering childhood exposure to these four contaminants from food. Its main tool is the action level: a level of contamination at which FDA may regard a food as adulterated. FDA stresses that an action level is not a permitted amount, and that guidance of this kind is not legally binding. The agency also says it does not need an action level to act against an unsafe food.

The table shows what was final when we checked on October 11, 2026. Figures are in parts per billion (ppb).

The January 2025 guidance applies to packaged processed foods sold for babies and children under two: jars, pouches, tubs and boxes, including purees and dry infant cereals.

FDA lists what it does not cover: infant formula, beverages, and snack foods such as puffs and teething biscuits. The agency says it is still collecting data on grain-based snacks to decide whether an action level is appropriate. Keep that in mind when reading labels on baby snacks, organic or not.

Formula is being handled separately. On April 29, 2026 FDA published test results for 312 formula samples and said it is working to establish action levels for contaminants in infant formula.

FDA's Closer to Zero timeline planned draft action levels for arsenic and cadmium in foods for babies and young children in 2025. Those drafts had not appeared when we checked.

FDA's list of guidance under development, dated June 29, 2026, names two documents it expects to publish by the end of December 2026: draft action levels for cadmium in processed food for babies and young children, and draft action levels for inorganic arsenic in food for babies and young children. A draft is a proposal. Final levels come after public comment.

For mercury, FDA says seafood is the main dietary source and points families to its joint advice with EPA about eating fish.

FDA is clear that the action levels are not meant to steer food choices and that parents should not throw out packaged baby foods or stop feeding certain foods. The AAP's advice is practical and applies whether you buy organic or not.
