Tamara, were you surprised to find this much Lead in a brand new coffee cup from Starbucks?
Frankly – even though I know how bad this brand has rated (from a toxicant perspective) over the years [I’d estimate I have personally tested more than a thousand Starbucks branded mugs for people over the last decade] – I am really shocked that a brand-new 2019 Starbucks product has Lead at levels this high.
Isn’t this illegal?
For those who are new to this website: While it is – incredibly – not in any way currently illegal to have this much Lead in a mug (!) in the U.S., it seems like – in this “post-Flint” era of Lead awareness – companies should do better than including one of the most potent neurotoxins known to man in dishware that is intended for use with hot / acidic beverages (tea/ coffee) on daily basis.
And in case someone from Starbucks is reading this post:
Starbucks — WHEN ARE YOU GOING TO STEP UP AND INSIST ON THE REMOVAL OF LEAD AND OTHER HEAVY METAL TOXICANTS FROM THE DECORATIVE COATINGS USED BY ALL VENDORS IN YOUR SUPPLY CHAIN? You are a huge company. Where’s your corporate responsibility and accountability when it comes to the planet, our children and their future? What possible excuse could you have for manufacturing brand-new high-Lead-content products emblazoned with your name??
And let’s be clear: the end product is not the only concern here…The big picture concern here is that you as a company are supporting/creating a demand for Lead-based pigments. Starbucks – this means you are supporting/instigating the demand for the mining, refining and manufacturing of Lead – along the entire global supply chain. Shame on you.
Let’s talk! (Seriously — I have been consulting for a LOT of companies recently; send me your products prototypes BEFORE you put them on your stores’ shelves and I can let you know if they have Lead, Cadmium, Mercury, Arsenic or Antimony BEFORE you unknowingly sell things like coffee mugs featuring neurotoxic-heavy-metals-laden-coatings to your unsuspecting customers!)

How much Lead did this mug have exactly?
When tested with an XRF instrument, this 2019 gold-glazed Starbucks brand mug (purchased new at a Starbucks store in Washington State in 2019) had the following readings:
On an exterior area with just the golden glaze:
- Lead (Pb): 15,700 +/- 400 ppm
- Barium (Ba): 693 +/- 70 ppm
On the black glaze on the interior of the mug:
- Lead (Pb): 764 +/- 45 ppm
- Barium (Ba): 1,509 +/ 87 ppm
- Chromium (Cr): 6,411 +/- 249 ppm
Focused on the white logo area on the interior of the mug:
- Lead (Pb): 630 +/- 42 ppm
- Barium (Ba): 1,734 +/ 98 ppm
- Chromium (Cr): 5,052 +/- 275 ppm
All tests were done for a minimum of 60 seconds each – using a freshly calibrated Niton XRF instrument (an XL3T XRF testing in “Consumer Goods” mode). Tests were repeated multiple times on each component to confirm the results. All test results reported on this blog are science-based, accurate, and replicable.
How much Lead is “too much” Lead?
For context, the amount of Lead that is considered unsafe (and illegal) in products “intended for use by children” is anything 90 ppm or higher in the paint, glaze or coating and anything 100 ppm or higher in the substrate (in the case of a mug, this would be the base ceramic of the mug.) These standards are for XRF-detectable total Lead content (not leach-test results – which is a different standard / different type of testing.) Dishes (including mugs) are not regulated in the same way as children’s items – as they are not considered to be “items intended for use by children.” In my opinion, this is a significant regulatory loophole — as frankly I don’t know any children who don’t use dishes.
Thank you for reading and for sharing my posts.
As always, please let me know if you have any questions!
