Organic Genmaicha Tao of Tea — Green Tea & Toasted Rice (Japan): 2024 Lab Report – Testing For Lead, Mercury, Cadmium, & Arsenic
Quick note from Tamara Rubin:
This has been my favorite tea for a zillion years (it seems… almost!). My grandfather used to share Genmaicha with us when we were very young children visiting him in San Francisco (it was one of his favorite teas). So when my husband and I discovered the Tao of Tea — a tea house in Portland, Oregon — shortly after we moved to Portland 22+ years ago, this is one of the first teas I tried.
Given this organic Genmaicha is sourced from Japan and imported / packaged by a responsible Portland-based company (check out their website here, this is a great Portland date spot too!) – I hoped it was a safer choice but I was not 100% certain.
We created a fundraiser to test the tea leaves themselves (dry) – and that has not yet funded (link here), but since I drink this tea nearly every day I thought I would do myself the favor of personally covering the cost to test the tea as prepared. I would still like to test it dry (to compare the results to the prepared tea, so we have that for context), but the lab report for this tea below is for the tea brewed as a beverage.
I decided to brew the tea EXTRA STRONG for a few reasons (not the least of which is that I like my tea strong!), primarily thinking that if was brewed extra strong it would be more likely to extract Lead from the leaves if there was any to be extracted:
- We started with Lead-free water from the filtered water tap at our kitchen sink (it has been tested and came back non-detect for Lead, with a low threshold of detection of one ppb – so the result for our water was “less than 1 ppb”)
- We put the tea in our Lead-free TeaBloom teapot (link here – https://amzn.to/3P41A2W – this brand converted to being Lead-free after we found Lead paint on their earlier models!)
- We boiled the water in our Lead-free electric kettle (link here – https://amzn.to/3ZONPtP )
- I then poured the water in the kettle over the tea leaves and let it soak for a while (5+ minutes).
- I then decanted the tea into a Lead-free mug (link here: https://amzn.to/403HH21) two times and poured it back over the leaves.
- I then (for good measure) let the tea sit steeping overnight (with the water fully covering the tea leaves).
- We then sent this brewed tea into the lab (basically having done everything we could to potentially increase the amount of Lead in the final beverage if any were present.
- The result was that the tea came back “non-detect” for Lead, with a low threshold of detection of 5 ppb (which is our current low threshold of detection though SimpleLab).
- I may test the beverage again in the future if we can find a lab that will test down to 1 ppb, and (again, as noted above) I would still like to send the dry tea leaves in for testing to compare the results of the dry tea leaves to the brewed tea (so please contribute to that campaign if you are in a position to do so!)
- In the meantime, here the link so you can also enjoy my favorite tea – from this wonderful, responsible, ethical, Portland, Oregon based company!: https://amzn.to/3Dp8Fsd

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, the products listed below (the first section of the list 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, 61 products in October 2024, and 31 products in November of 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.
More Key Points To Consider:
- There are almost no reasonable safety limits proposed for toxicant contamination (heavy metal contamination specifically) of foods and supplements consumed by adults (or by the general population) in the United States.
- Any available proposed safety thresholds (and guidance) for foods and supplements consumed by adults are not currently set at levels that are protective of human health – given practical / actual consumption patterns of foods (vs. manufacturer defined serving sizes)
- The above point is especially important given children eat all foods, not just foods marketed for consumption by children (for example: find me a pre-teen that won’t go through an entire 5 ounce / 5-serving bag of potato chips in one sitting!)
- Our focus is (as always) on the health of children.
- By applying the standards proposed by the Baby Food Safety Act of 2021 to all foods and supplements – we are working more in line with standards that are protective of human health (for all!) given all scientific and medical experts agree that there is no safe level of Lead exposure for human beings.
- Said another way: You would never be eating a snack chip out of a bag and say to your 5 year old child “this product is only marketed for consumption by adults, so you cannot eat it.” That would be ridiculous. Kids eat what we eat, so everything that goes into our bodies in an attempt to nourish us and support our health and well being should be appropriate for any age consumer (not just a demographic designated by the manufacturer based on irrelevant age-group related toxicity standards for a specific product or ingredient).
- Remember: There is no save level of Lead exposure for human beings. Period. This is a non-negotiable point that everyone in the scientific and medical community – everyone who researches Lead poisoning – agrees with.

thank you so much for what you are doing! I havent been to your website in a while and didnt realize you were testing foods. I found a lot of foods I eat here and am dismayed to see many of them tested high, like Eden Millet and Peanut Butter Perfect Bars. Can you test Montana Gluten Free Organic Raw Oatmeal and Once Again Organic Creamy Peanut Butter?
Hi Abbie – here’s how to nominate foods for testing:
