Bob’s Red Mill Gluten Free 1 to 1 Baking Flour tested positive for unsafe levels of Arsenic & Cadmium: November 2024 Lab Report
Quick note from Tamara Rubin:
As anticipated, Bob’s Red Mill Gluten Free 1 to 1 Baking Flour tested positive for unsafe levels of Arsenic and Cadmium (“unsafe” when considered as a product that may be consumed by young children). For more information about the standards we are using as a metric to determine safety, continue reading below. To quote Star Wars (loosely): “Nothing new here… move along….”
We have not yet found a single Gluten Free flour product that tested non-detect for toxicants.

Important Background: What is an Action Level?
Please note the following key points:
The original lab report for this product is below (at the bottom of this page).
The graphic above shows the levels of metals detected in this product (in red) along with the low threshold of detection (in orange, above the action levels discussed/ or in green, below the action levels discussed) for each metal not detected with the laboratory testing Lead Safe Mama, LLC had completed for this product. The numbers are juxtaposed (in blue) to the “Action Level” proposed by the medical and scientific community in 2021 as part of the Baby Food Safety Act. For this round of testing, SimpleLab (our laboratory testing provider) had a change of labs and their low threshold of detection is slightly higher than in previous testing rounds.
- These 2021 levels were proposed as “Action Levels” because they are (in fact) protective of human health.
- An “Action Level” is NOT the same as a “Maximum Allowable Level.”
- Many food manufacturers misinterpret guidance on heavy metals to mean “allowable levels” and consider it reasonable for products to test positive below these levels.
- This is a (perhaps intentional?) misunderstanding/ misinterpretation the food industry makes — a misunderstanding that food manufacturers use to justify the presence of heavy metals in products.
- Heavy metals accumulate in the body.
- It is the cumulative/ aggregate impact of heavy metal exposure (over a lifetime) that makes even small/ incidental/ seemingly trivial exposures particularly damaging and dangerous. You can read more about that here.
- Once a food product has the amount of heavy metal (Lead, Cadmium, Mercury, or Arsenic) noted (above) as the “Action Level,” that product is officially considered (by the scientific and medical community) unsafe for consumption by children as toxicants (found at-or-above these levels) are in the range of heavy metal levels that have been demonstrated to cause lasting harm.
- Action Levels are unrelated to serving size.
- Action Levels are relevant for any amount of a food product that may be consumed (any quantity of the food in question).
- PPB (parts per billion/ ppb) measurements are a percentage (albeit a very small percentage) and apply to any quantity of the food product tested.
- For more discussion about serving size considerations (and why relying on “serving size” to limit toxicant exposure is not a relevant metric/ not a metric protective of human health), read this article.
- These “Action Levels” proposed in 2021 are the levels at which the scientific and medical community believe the manufacturer (or government) needs to take ACTION to fix the problem.
- One “Action” would be for the manufacturer to take steps to reduce the levels of toxicants in the food product.
- Another “Action” would be for the manufacturer to cease sales of the product until the product could be made safe.
- Another “Action” would be for the manufacturer to inform the public that a specific food product has an unsafe level of the metal detected at-or-above the “Action Level” — making a highly-visible public announcement regarding which relevant batches of the product should be recalled/ no longer consumed.
- The Action Levels proposed with the Baby Food Safety Act of 2021 were not arbitrary toxicant levels, but were proposed because they are the levels most protective of human health. However, the Baby Food Safety Act of 2021 was not passed into law.
- Regardless of the fact the Baby Food Safety Act of 2021 never passed into law — and it is therefore legal to have foods and supplements marketed for consumption by children test positive for Lead, Cadmium, Mercury, and Arsenic at-or-above these levels — these Action Levels still reflect the current (modern/ relevant) advice of the medical and scientific communities as levels both achievable by the industry and safeguards of infant and toddler health.
- Food and supplement industry lobbyists fought against formalizing these proposed “Action Levels” as a government standard, alleging the levels were unachievable.
- The list of safer choices (below) clearly demonstrate these Action Levels as achievable across a range of food types (salt, flour, coffee, oatmeal, chia seeds, hemp seeds, soy milk, packaged fruit-based snacks, beverages, and more).
- The legitimacy of these levels as “Action Levels”/ “Levels of Concern” (even though they were not adopted as law) is mirrored by the legitimacy of the American Academy of Pediatrics’ level of concern for Lead in water, which is 1 ppb despite the FDA’s official “level of concern” for Lead in water being 15 ppb (you can read more about that here).
“Simply Not Achievable”
To reiterate: While the packaged, processed food industry would have consumers (and the government) believe the standards proposed in 2021 are unachievable, this industry position (an oft-rearticulated response to nearly every set of laboratory test results for food and supplements that we have published to date) is simply not true.
It is possible to make safer processed, packaged food products and supplements that fall well below the safety limits for toxicants proposed within the Baby Food Safety Act of 2021. To wit, all of the 25 products listed below tested “non-detect” for Lead, Cadmium, Mercury, and Arsenic — several even tested non-detect for Lead with the low threshold of detection being “less than 1.5 ppb.”
Below is an EXPANDING list of products (foods and supplements) that have tested “non-detect” for Lead, Mercury, Cadmium, and Arsenic with independent, third-party, crowd-funded laboratory testing coordinated by Lead Safe Mama, LLC (an Oregon-based small business with a unique community-collaborative business model and a focus on consumer goods safety and childhood Lead poisoning prevention).

Hello! We are continually working on publishing a LOT of test results very quickly this month. We sent 67 products to the lab for testing in September 2024 and 61 products in October 2024. We have not yet reported on all of those products as we are still waiting to receive final reports from the lab for many of them.
We will be updating this section of each article (with more information about the specific product and other similar products for context) as time permits, but we wanted to ensure the greater Lead Safe Mama community (and the general public) had access to this scientific data (about foods and supplements in their home) as quickly as possible.
Please scroll down to see the full laboratory test report for the product pictured above. Thank you for your patience.
As there are almost no reasonable safety thresholds proposed for toxicants (heavy metals) consumed by adults (in foods and supplements), our focus is (as always) on the health of children. The available proposed safety thresholds (and guidance) for foods consumed by adults are not set at levels protective of human health and are therefore irrelevant to the work we do here at Lead Safe Mama, LLC.

We have not yet found a single Gluten Free flour product that tested non-detect for toxicants.
So what are celiacs supposed to eat?
In general I recommend avoiding flour products whenever possible, and trying to create a flour-free diet. A diet of substitutions is not a healthy diet, and flour has never been healthy for humans. The bigger question is “do you want to avoid cancer?” (is there a history of cancer in your family?)… if the answer to that is “yes” (as it is for me, I don’t want to die the horrible death from cancer that my mother died, that my father died, that my mother-in-law died) – then trying on the idea of limiting flour products (based on the fact that they appear to be mostly contaminated) is something worth exploring.
We are working on testing more flours as well – here are our open fundraisers: https://www.gofundme.com/s?q=tamara+rubin+flour&location-description=Portland%2C+OR&location-lat=45.520247&location-lng=-122.674195&c=342
Here’s the link to all of the flour products we have tested so far:
https://tamararubin.com/category/flour/
If you are going to try to eliminate one source of toxicants from your life (just one) I do recommend trying to eliminate flour – as it is a staple of the diet for so many and therefore likely one of the biggest contributing factors (for Arsenic and Cadmium). I also recommend eliminating seaweed, chocolate, cassava-flour-based products, and potato chips (and packaged food in general to the degree you can).
I am not a doctor – but it is very possible your gut will heal if you eliminate these things – as toxicant exposures are well known to be the CAUSE of GI issues.
