- Tamara owns and runs Lead Safe Mama, LLC — a unique community collaborative woman-owned small business for childhood Lead poisoning prevention and consumer goods safety.
- Since 2009, Tamara has been conducting XRF testing (a scientific testing method) using the exact instrumentation employed by the U.S. Consumer Product Safety Commission to test consumer goods for toxicants (specifically heavy metals — including Lead, Cadmium, Mercury, Antimony, and Arsenic).
- Since July of 2022, the work of Lead Safe Mama, LLC has been responsible for 5 product recalls (FDA and CPSC).
- All test results reported on this website are science-based, accurate, and replicable.
- Items that Lead Safe Mama, LLC reports on are tested multiple times to confirm the results published (for each component tested).
- Recent notable press… There has been too much to mention already in 2024! Please check out our press page to see some of the amazing coverage of our work so far this year!

The graphic below (scroll down) has a response that Stanley sent to a Lead Safe Mama community member who inquired about Stanley’s use of Lead in their insulated Stainless Steel products (including the popular 40 ounce “Stanley Cup”). In this short response, they admit that they are aware they use a Leaded pellet to seal the vacuum (and create the insulative properties of these products).
What Stanley neglected to state (and what they, in fact, downplay with this response), is that the “pellet” they melt to create the “sealing dot” for the vacuum seal of these product is not just made with “some Lead” but appears to be made with an alloy that contains between 400,000 to 600,000 ppm Lead. (You can see the testing demonstrating this in the videos embedded at the top of our original article about this product linked here.)
The amount of Lead we found (with independent scientific testing) in these insulated Stainless Steel Stanley-brand products is a standard alloy for Lead solder (typically 60% Lead and 40% other metals), however the Consumer Product Safety Improvement Act of 2008 (CPSIA) states that any component of any product with a SUBSTRATE (underlying material) that tests positive for levels higher than 100 ppm Lead makes that product illegal (as an item intended for use by children). While this regulatory standard (this total-content limit for Lead in consumer goods) does not apply to the 40 oz “Stanley Cup” (as it is not an item intended for us by children), this law DOES apply to any insulated Stainless Steel children’s products made by Stanley.
Additionally, Stanley’s statement that the Leaded component is “completely enclosed by a stainless-steel cover, making it inaccessible to consumers” is a false statement. At least several dozen Lead Safe Mama community members have reported (since 2023) that the “stainless-steel cover” has come off with normal use of the product (using the product as intended, not abusing the product or using it in unexpected ways). When the cover comes off, it creates a significant potential Lead exposure risk to the user, making the product illegal if the intended user of the product is children.
As a result, we expect that the Consumer Product Safety Commission will likely agree that Stanley’s insulated Stainless Steel children’s products (which are made with the same construction method and have the same failure mode as their adult products) contain an unsafe level of Lead and are a violation of the CPSIA. Given this information, Lead Safe Mama, LLC will be submitting a violation report to the CPSC this weekend regarding the unsafe (and illegal) levels of Lead in Stanley’s insulated Stainless Steel children’s products.
The following Lead Safe Mama, LLC initiated recalls support this concern:
If you own an insulated Stainless Steel Stanley-brand product and the bottom disc has come off (see the image at the top of the page with arrows that point to the bottom disc, and see the other articles linked above for more examples of this issue), you should stop using this product, call the company, and ask for a refund (then set the product aside, away from children’s reach until the CPSC has a chance to respond). Additionally, we would appreciate if you would comment on this article (especially if the product you own is a Stanley children’s product) and we may follow up with you to request more information that we can include in the CPSC violation report we are filing.
- There is no safe level of Lead exposure to humans (and especially to children).
- It just takes a microscopic (literally invisible) amount of Lead to poison a human being.
- Fundamentally, as HydroFlask has demonstrated for nearly a decade, it is not required to use Lead for the application used in these insulated Stainless Steel products.
- The fact that it is an “industry standard” does not make the use of Lead acceptable, nor does it make it always legal (in the case of children’s products).
- Alternative Lead-free materials have been identified by the industry, are readily available, and work well.
- As consumers, we must demand that companies do better and stop using ANY Lead in ANY products used for food or beverage consumption or storage.
- This is not rocket science, it is very simple and easily achievable.
Thank you for reading. Thank you for sharing this with anyone you know who may own one of these Stanley products, especially if they let their children use these products (or if they own the children’s version of the Stanley products).
