Toxic Metals Found in All Rice Samples in New Study

FRIDAY, May 16, 2025 (HealthDay News) — A new report says rice sold in U.S. stores contains toxic heavy metals, including arsenic, cadmium, lead and mercury.

The report — released by Healthy Babies, Bright Futures — found arsenic in 100% of rice samples tested from stores in 20 metro areas, including New York City, Los Angeles and Miami, CBS News reported.

What's more, 1 in 4 samples exceeded the U.S. Food and Drug Administration’s (FDA) arsenic limit for infant rice cereal, which is 100 parts per billion (ppb). 

That rule was set in 2021, but it only applies to rice cereal made for babies — not to the rice that the rest of the family eats.

"No such limit exists for rice itself — the bags and boxes of rice served at family meals — despite it being widely consumed by infants and toddlers," the authors note. 

The study tested 145 popular brands of rice, including Trader Joe’s and Ben’s and Goya. On average, total heavy metal levels across the samples ranged from 63 to 188 ppb, with some going as high as 240 ppb, CBS News said. 

Arsenic showed up at the highest levels, followed by cadmium. Lead and mercury were found in smaller amounts.

Responding to the report, the USA Rice Federation acknowledged consumers' concerns.

"We know that arsenic in food is alarming for many consumers and that you may have questions," the group said in a statement emailed to CBS News. "And while we do not agree that there is a public health safety issue as a result of trace amounts of arsenic in rice, we will continue to work with the U.S. Food and Drug Administration to ensure the U.S. rice supply meets any threshold established."

The FDA and National Institutes of Health (NIH) note that inorganic arsenic — the form found in higher amounts in this study — is more toxic than the naturally occurring kind. The Environmental Protection Agency (EPA) also classifies it as a carcinogen, or a cancer-causing substance.

To lower your exposure, the report offered three tips:

1. Cook rice like pasta. Use 6 to 10 cups of water per 1 cup of rice, then drain any extra before eating.

2. Try alternatives. Foods like quinoa, barley and couscous have lower levels of heavy metals.

3. Choose rice wisely. White rice from California, sushi rice, Thai jasmine and Indian Basmati tend to have lower levels of heavy metals and elements. Avoid brown rice, white rice grown in the Southeastern U.S. and arborio rice from Italy, which were shown to have higher levels.
