Pink Silicone Dish by Bumkins (Made in China, 100% Food Grade Silicone): 11 ppm Cadmium (safe by all U.S. and international standards.)

Published: February 10, 2022 – Friday

Overview: 

Cadmium is found at trace levels in most silicone that I have tested; Cadmium is a known carcinogen. I have, however found examples of silicone kitchenware (or components of silicone kitchenware) that have tested negative for Cadmium — so it is definitely possible to make silicone products without trace Cadmium contamination.

That said, the amount of Cadmium found in this dish (in the 5 to 14 ppm range) is considered safe by ALL standards even the strictest standards (from the State of Washington and the country of Denmark.) [Denmark considers consumer goods safe for use by children if Cadmium levels fall below 75 ppm; in the U.S., Washington State considers items safe for use by children if Cadmium levels fall below 40 ppm.] You can learn more about the concerns for Cadmium by clicking this link.

Other considerations:

• From an ethical and political standpoint, I hold the perspective that items intended for use by children should be Cadmium-free in all components whenever possible.
• I am primarily concerned for the presence of Cadmium in silicone products like baby bottle nipples (or silicone chew toys – often sold for use by kids with sensory issues), where a child might have that product in their mouth for several hours a day (with normal use as intended.)
• The presence of Cadmium seems to sometimes (but not always) be associated with the use of pink and red pigments in silicone. I think companies should reconsider the use of pink and red pigments as a first step in trying to eliminate trace Cadmium contamination from their silicone products. [I have found some clear / white silicone products to test positive for Cadmium, so this is not a rule across the board, but a first step in addressing considerations on this issue.]
• While I don’t necessarily have a concern for trace (low) levels of Cadmium found in a dish like this (given normal use of this product as intended), I do have more concern for Cadmium found in silicone products that might be used in the oven to cook food (especially food-contact products used at high temperatures – like one normally uses in an oven – for extended cooking times [here’s one example]). This concern is amplified by the fact that consumers do not have any way to test for Cadmium content and therefore no way to know if a product might test positive for high levels of Cadmium, trace levels of Cadmium or no Cadmium at all.
• Separate from the concern for Cadmium contamination of silicone, silicone products are also sometimes contaminated with Lead at levels that are above what might consider to be “trace contamination.” Here is one example from KitchenAid.
• As a result of the above points (and especially the potential for high levels of both Lead and Cadmium contamination in “food grade” silicone), I never recommend any silicone products on this website.
• Separately – I have personally chosen to limit silicone products in our home to products that will not be used to cook food; one example that does not concern me in this context is silicone ice cube trays (we got ours from Ikea). [I have found that silicone products that I have tested from Ikea tend to test negative (or at least positive at lower levels) for trace Cadmium contamination. Here is one example. ]

Tamara Rubin is a Federal-award-winning independent advocate for consumer goods safety and a documentary filmmaker. She is also a mother of Lead-poisoned children. Tamara’s sons were acutely Lead-poisoned in August of 2005. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. Tamara uses XRF testing (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals), including Lead, Cadmium, Mercury, Antimony and Arsenic. All test results reported on this website are science-based, accurate and replicable. Items are tested multiple times to confirm the test results for each component tested. Please click through to this link to learn more about the testing methodology used for the test results discussed and reported on this website.
