Ramen & Rice Noodles Tested for Arsenic & Lead –Guide

What ramen & rice noodle products can you safely feed your family that have been tested for toxic arsenic, the most common contaminant? Mamavation accepted rice & noodle donations from women across the United States and sent them to an independent EPA-certified laboratory to test for arsenic, lead, cadmium & mercury. This consumer study will report how the ramen & noodle brands we sent to the laboratory performed, as shown at the bottom of this post. You’ve trusted Mamavation to bring you investigations like (1) safest jasmine rice for arsenic & lead,  (2) safest coffee from pesticides & PFAS, (3) safest cooking oils tested for phthalates, and (4) best water filters to capture PFAS “forever chemicals.” Now join us for our latest consumer study on rice and see which ramen & rice noodle brands are the safest from arsenic.

Mamavation Found Arsenic, Lead, & Cadmium in Ramen & Rice Noodles

How much arsenic is in a typical cup of rice ramen & noodles? Let’s find out. Previous studies found high levels of arsenic in most rice products, so we created a rice & noodle consumer study based on the exact needs of Mamavation community members. Mamavation sent 57 rice, ramen, & rice noodle products to an EPA-certified laboratory to test for total arsenic, lead, cadmium, & mercury. Because rice is the most significant source of arsenic (other than drinking water) most Americans have daily, we relied on donations from our audience to test exactly what they were already using.

Jasmine rice, basmati rice, brown rice, long-grain rice, parboiled rice, sushi rice, heirloom rice, forbidden rice, & ramen rice noodles were all sent to the laboratory and had various levels of arsenic and other heavy metals present. Here are some of the main findings:

• 98% of rice samples contained detectable total arsenic. That’s 56 out of 57 rice products. And, 100% of ramen & rice noodle products had detectable total arsenic.
• Ramen & rice noodle arsenic levels ranged from 0.013 ug/g to 0.166 ug/g total arsenic. This can also be described as 13 to 166 parts per billion (ppb).
• The average ramen & noodle product contamination was 106 ppb total arsenic; however, the average rice product contamination from the entire rice group was 113 ppb total arsenic.
• Highest Arsenic Products: Mamavation sent two products with over 10 mcg of total arsenic for every 45 mg of rice for more testing of inorganic arsenic. Neither of those products were ramen or noodles, but they came back with concerning levels of inorganic arsenic– 175 ppb and 222 ppb total inorganic arsenic. These samples were from China, Heilongjiang Province, and Louisiana.
• Geography of Highest Arsenic: Rice products with the highest total arsenic were from China, Thailand, Louisiana, Texas, & South Carolina.
• Geography of Lowest Arsenic: Rice products with the lowest total arsenic were from California, India, Korea, Vietnam, Thailand, & China.

Linda S. Birnbaum, Scientist Emeritus and Former Director of the National Institute of Environmental Health Sciences and National Toxicology Program & Scholar in Residence at Duke University, Adjunct Professor at the University of North Carolina, & Yale University had this to say after she reviewed this consumer study: “Pay close attention to how much arsenic is in your rice if you are raising young children or are pregnant. Mamavation has made this easy for you to navigate with their rice testing. Overall, this is a big problem for women who are pregnant, feeding small children, and people who consume lots of rice. So if you eat lots of rice, it’s best to opt for safer brands or types of rice lower in arsenic.”

Health-Related Impacts Linked to Overconsumption of Arsenic

Arsenic is a carcinogen that, in chronic exposure, is linked to bladder, lung, and skin cancers. Its most toxic form, inorganic arsenic, is found in the environment and around industrial processes. Early-life exposures to inorganic arsenic in utero are especially dangerous. Here are some additional health-related impacts linked to overconsumption of arsenic.

• Spontaneous abortion & stillbirths
• Increase in preterm births
• Neurodevelopmental disorders
• Behavioral disorders
• Cancer (bladder, lung & skin cancers)
• Skin lesions
• Cardiovascular disease
• Diabetes

For most of the world, exposure to arsenic is through contaminated groundwater. Inorganic arsenic is naturally present at high levels in the groundwater in regions of Argentina, Bangladesh, Cambodia, Chile, China, India, Mexico, Pakistan, the United States of America, and Vietnam.  Acute poisoning results in vomiting, abdominal pain, and diarrhea, followed by numbness and tingling of the extremities, muscle cramping, and even death, in extreme cases. Children are especially vulnerable to arsenic, and in such rare cases, they are referred to a medical toxicologist, Poison Control Center, or Pediatric Environmental Health Specialty Unit for possible chelation therapy. You can check to see the arsenic levels in your public water district here through the Environmental Working Group Tapwater Database.

How to Lower Asenic Exposure for Children

If you are pregnant or caring for small children, lowering your exposure to arsenic is important. There are many things you can do, and we would love to help you get started!

• Drinking Water: The official recommendation from health professionals is to consider drinking bottled water in areas with elevated levels of arsenic in drinking water. You can check the water in your area here. Unfortunately, boiling water does not remove arsenic. However, we also worry a bit about exposing children to the microplastics in bottled water, so perhaps the best solution is getting a good water purifier for your home. Finding a good water purifier that can reduce arsenic levels is tricky. Most systems do not filter arsenic well, but we have linked some sound systems that can tackle that below. Here are our three water filter recommendations specifically for handling arsenic in water:
  •  Clearly Filtered 3 Stage Under the Sink Water Filtration System with Affinity Filtration Technology (or you can alternatively use their Clearly Filtered Water Pitcher with Affinity Filtration Technology)  (This link will deduct 10% off purchase.) 
  • AquaSauna SmartFlow Reverse Osmosis (Use discount code “MAMAVATION” for 10% off purchases!)
  •  AQUA TRU Countertop Water Filtration Reverse Osmosis or Under the Sink model (This link will automatically deduct $100 off a unit for you at checkout.)
• Diet: Generally, varied diets from whole foods are recommended instead of relying on prepackaged rice products.
  • Limit consumption of anything derived from rice, like rice syrups or rice cereals. Check the ingredients in your packaged foods and limit the amount of food consumed that contains rice.
  • Iron-fortified rice cereal is not the best first grain introduced to infants; instead, other options like oats, barley, and multigrain cereals should be introduced. These alternative grains can become a staple among older kids too.
  • Preparing Rice: When preparing rice for children, rinse it before cooking. Cook the rice in plenty of water, similar to how you would cook pasta. The arsenic will pull out of the rice into the water, and you can dump it out. This will lower the total arsenic you are exposed to.
  • Switch from brown rice to white rice. Rice without the hull typically has less arsenic.
• Limit consumption of fruit juices, especially grape and apple. Here are our recommendations for the safest apple juice brands based on a prior study released by Consumer Reports looking at arsenic levels:
  • 365 Everyday Value (Whole Foods) Organic Apple Juice, 100% Juice
  • Juicy Juice Organics 100% Juice, Apple (single juice box)
  • Honest Kids Organic Juice Drink, Goodness Grapeness (single juice box)
  • Simply Balanced (Target) Organic Apple Juice, 100% Juice
• Avoid Chromated Copper Arsenate (CCA) when treating wood or decking and opt for safer alternatives. Here are some better options for decking and furniture.
  • Vermont Natural Coatings Bohme’s Terra Plus Exterior Deck Stain
  • Vermont Natural Coatings Penetrating Waterproofer Infused with Juniper
  • Vermont Natural Coatings PolyWhey Exterior Penetrating Stain
  • Rubio Monocoat Hybrid Wood Protector
• Avoid allowing your children to play in dirt around industrial areas, especially locations with smelters, welders, woodworkers, chemical plants, glass manufacturing, and maintenance crews.

Types of Rice — What We Tested

There are two main types of rice: Indica and Japonica. Indica rice, better known as long-grain rice, such as Basmati and Jasmine rice, is long and slim. Japonica rice is a medium to short-grain rice and is stickier, shorter, or rounder. Wild rice is not true rice because it comes from a grass family, but we know you eat it so we won’t be splitting hairs here. Here are the types of rice we tested, broken into categories:

• Basmati Rice — Basmati rice is a long-grained rice with a nutty flavor and aroma. This type of rice becomes very fluffy when cooked and used in South Asian and Middle Eastern cuisines.
• Jasmine Rice — Jasmine rice is another long-grained rice with a floral scent and slightly sweet flavor, native to Southeast Asia. Jasmine rice from Thailand is also known as “Thai Horn Mali”.
• Brown Rice — Brown rice is a whole grain rice containing the rice kernel, including the germ and the endosperm. This rice is higher in fiber. Technically, any other rice that maintains its structure can be a brown rice. Brown rice typically has more arsenic than white rice because of the hull.
• Black “Forbidden” Rice is considered a whole grain because it has retained its bran, germ, and endosperm. It’s very dark in color and not as popular in the US as other rice categories.
• Wild Rice — This rice has more fiber and protein than other rice. The colors can vary.
• Rice Noodles — We included this category as noodles made from rice. Some products are transparent about what type of rice they use, while others are not.
• Parboiled — This rice is partially cooked in the husk, and then the husk is removed. This is also referred to as “easy cook” rice.
• Sushi & Other Short-Grain Rice — This category is a general section where we have to stuff many additional types of rice, like sushi rice and sticky rice.

How Arsenic Finds Its Way Into Rice & Rice Cereals

How does arsenic contaminate rice? The answer to that question is both complicated and straightforward. Rice is the number one source of arsenic for most Americans, but if you eat lots of chicken, mushrooms, or seafood, your arsenic levels may be even higher. Here are the main exposure pathways for arsenic in rice:

• Geographic locations and farming practices in that area can impact the arsenic in rice. For instance, rice from California may have less arsenic than rice from Texas or Louisiana.
• Rice paddies take up more arsenic than other plants, so the naturally present arsenic will increase in rice in a way that doesn’t happen in other plants.
• The local water supply could have higher arsenic levels, and if used for irrigation, it will increase the amounts in rice. Certain areas like Los Angeles, Houston, & Spokane have higher levels of arsenic in the water.
• Legacy Pesticide Use: Rice farms that used to be other types, like cotton or tobacco farms, could already have arsenic contamination in the soil from previous pesticide use.
• Most rice paddy farms are irrigated heavily with water, turning them into mud patches that never dry and, over time, concentrate arsenic.
• Arsenic-containing drugs: Sometimes arsenic-containing drugs and feed additives are fed to chickens to keep them from getting sick, but this also increases arsenic in their feces. This arsenic-filled chicken poop can be used in composting, which can get into the general food supply and can be taken up by plants or eaten by farm animals.

Mamavation’s Investigation on Ramen & Rice Noodles Tested for Arsenic, Lead, Cadmium, & Mercury

To recap, Mamavation sent 57 rice products to an EPA-certified laboratory for testing for arsenic, cadmium, mercury & lead. 98% of rice products had detectable amounts of total arsenic. However, 100% of the rice products contained some detectable heavy metal.

Mamavation accepted rice donations from women across the United States in the following categories: jasmine rice, basmati rice, sushi rice, long grain rice, brown rice, rice noodles, forbidden rice, wild rice, and parboiled rice. After receiving the rice, we recorded the information, took pictures, and sent the products to an EPA-certified laboratory for analysis. Rice that was above 0.22 mcg/g (10 mcg of arsenic per 45-gram serving), was sent back for more inorganic arsenic testing. We then estimated inorganic arsenic in other products by using a summary assessment of inorganic arsenic in rice published in 2024. Based on that study, we estimated that inorganic arsenic accounts for 72.7% of the total arsenic found. We included those estimations with all the products in the raw data below.

We are releasing the raw data in different categories:

• jasmine rice,
• basmati rice,
• long grain rice,
• brown rice,
• rice ramen and rice noodles,
• sushi & short-grain rice
• all rice products together

The final rice-related investigation that will be posted will be a compilation of all rice products together. The raw data released in this investigation will focus on Ramen & Rice Noodles. We divided the rice products into 3 categories according to contamination levels. These levels reflect the overall levels of heavy metal contamination in each product but do not follow specific government recommendations.

• ug/g = 1 ppm = 1000 ppb
• ug/kg = 1 ppb
• <MRL means less than “maximum residue limit,” which means it can be found, but it’s so small it can’t be quantified.
• ND = non-detect
