Apples do contain trace amounts of arsenic, but the levels in fresh fruit are extremely low and not a health concern for most people. Apple juice has received more scrutiny, with FDA testing finding total arsenic concentrations ranging from 1 to 45 parts per billion (ppb) across 160 samples. The FDA now enforces an action level of 10 ppb for inorganic arsenic in apple juice, the same standard the EPA sets for drinking water.
Why Apples Contain Arsenic
Arsenic shows up in apples for two reasons: it occurs naturally in soil, and it lingers from decades of pesticide use. From the 1890s through the mid-20th century, a chemical called lead arsenate was the most widely used pesticide in the United States, recommended by the USDA and sprayed on millions of acres of crops. Apple orchards were among the heaviest users because lead arsenate was highly effective against the codling moth, a major apple pest. Growers in some areas sprayed their trees every week during growing season.
Lead arsenate was designed to persist in the environment, and that persistence is exactly the problem. Once the chemical reached the ground through overspray, rain runoff, or fallen fruit and leaves, it separated into lead and arsenic that bound to particles in the topsoil. The arsenic remains in the top 12 to 18 inches of soil decades later. Although lead arsenate was finally banned in 1988, apple trees grown in formerly treated soil can still absorb small amounts of arsenic through their roots.
Where the Arsenic Ends Up
Apple trees absorb arsenic from soil and distribute it through the fruit in very small quantities. The flesh and peel of a whole apple carry only trace levels. Apple seeds, which sometimes come up in arsenic discussions, actually contain a small amount of cyanide rather than arsenic, and the hard seed coating prevents it from being released during digestion.
Apple juice tends to have higher concentrations than whole fruit because juicing concentrates whatever is present in the fruit and because some manufacturers have historically sourced apples from regions with more contamination. That said, levels have dropped significantly over time. When Consumer Reports tested apple juices sold in the U.S. in 2018, only 1 out of 22 products (about 5%) had an average inorganic arsenic concentration above the 10 ppb action level.
Inorganic vs. Organic Arsenic
Not all arsenic is equally harmful. Inorganic arsenic is the form that poses real health risks, and it’s the type that regulators focus on. Organic arsenic (which has nothing to do with organic farming; the term refers to its chemical structure) is far less toxic and passes through the body more quickly. Both forms have been detected in apple juice, but the FDA’s 10 ppb limit specifically targets inorganic arsenic because that’s the form linked to health problems with long-term exposure.
How Apples Compare to Other Foods
Apples are far from the biggest source of dietary arsenic. Rice is a much greater concern because rice plants are especially efficient at absorbing arsenic from flooded paddies. Grape and pear juices also contain inorganic arsenic at levels comparable to apple juice, sometimes exceeding the drinking water standard. For context, the arsenic in a glass of apple juice that meets the FDA’s limit is at or below what you’d get from a glass of water that meets EPA standards.
If you’re trying to minimize arsenic in your diet overall, paying attention to rice consumption (especially for young children) is more impactful than worrying about apples. Varying the types of grains and fruits you eat is a simple way to avoid overexposure to any single contaminant.
Health Risks of Low-Level Arsenic Exposure
The arsenic levels found in apples and apple juice are well below the thresholds associated with chronic health problems. Still, it’s worth understanding what long-term inorganic arsenic exposure can do at higher levels. Studies on populations exposed to arsenic through drinking water have found associations with skin changes, cardiovascular problems, and increased risk of certain skin cancers. In children, chronic exposure has been linked to lower verbal IQ scores and reduced long-term memory, with effects proportional to the dose.
These findings come from communities exposed to arsenic concentrations in water far higher than what you’d encounter from eating apples. The concern with food-based arsenic is cumulative exposure from multiple sources over time, not any single apple or glass of juice.
Reducing Arsenic on Fresh Apples
If you want to minimize any residues on fresh apples, a few simple steps help. Washing under running water removes dirt, germs, and some surface residues. Peeling takes it a step further, since the outer skin is the first point of contact with environmental contaminants. The FDA does not recommend using soap, detergent, or commercial produce washes, as none of these have been shown to work better than plain water.
For apple juice, choosing products from manufacturers who test for heavy metals provides an extra layer of assurance. Most major brands sold in the U.S. now fall well below the FDA’s 10 ppb action level. For young children, who are more vulnerable to arsenic’s effects because of their smaller body weight and developing brains, varying their beverages rather than relying heavily on juice is a practical way to limit exposure.
