Introduction (for those new to this website):
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, her sons were acutely Lead-poisoned in 2005. Since 2009 Tamara has been using 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. Tamara’s work was featured in Consumer Reports Magazine in February of 2023.

Testing is based on new product samples tested in 2017
When tested with an XRF instrument the Dr. Brown brand glass baby bottle pictured here (along with the related components also pictured) all tested negative (non-detect/ND) for Lead (within the limits of detection of XRF technology testing in consumer goods mode). However, two components (the glass bottle and the silicone nipple) did test positive for trace levels of Cadmium (considered safe by all current standards). When a toxicant is positive at a “trace” level, that means it is a very low level (generally considered insignificant) and considered a contaminant of the product components, meaning it’s not generally likely to be an added ingredient or feature of a product given the levels found.
XRF test results for the product pictured:
- Cadmium Readings:
- Glass bottle: 9+/-5 ppm
- Nipple: 14 +/- 5 ppm.
Important points to note:
- All other components were Non-Detect for Cadmium.
- All components were Non-Detect for Lead (Pb), Mercury (Hg), and Arsenic (As).
- For more information about the concern for Cadmium in consumer goods, please read my “Cadmium Concerns” post here.
- While I would not necessarily choose to use this product for a member of my family, here’s my Amazon affiliate link* for this product: http://amzn.to/2vREYaX
I prefer these three brands of glass baby bottles (from a toxicant perspective, these three brands have tested the cleanest):
- Brand one (click to see on Amazon)
- Brand two (click to see on Amazon)
- Brand three (click to see on Amazon)
