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.

The readings below are full XRF readings for each component of the PLASTIC Lansinoh bottles. The readings for the GLASS Lansinoh bottles (which do test positive for Lead) can be found at this link. To see all of the LeadSafeMama.com articles related to Lansinoh brand baby bottles, click here.
Reading #1) Clear plastic cap for nipples
60-second reading
- Lead (Pb): non-detect
- Cadmium (Cd): non-detect
- Tin (Sn): non-detect
- Mercury (Hg): non-detect
- Selenium (Se): non-detect
- Barium (Ba): 267 +/- 142 ppm
- Arsenic (As): non-detect
- Chromium (Cr): non-detect
- Antimony (Sb): non-detect
- Iron (Fe): 100 +/- 29 ppm
- No other metals were detected in consumer goods mode.
Reading #2) Clear silicone nipple
60-second reading
- Lead (Pb): non-detect
- Cadmium (Cd): 13 +/- 4 ppm
- Tin (Sn): non-detect
- Mercury (Hg): non-detect
- Selenium (Se): non-detect
- Barium (Ba): non-detect
- Arsenic (As): non-detect
- Chromium (Cr): non-detect
- Antimony (Sb): non-detect
- Niobium (Nb): 397 +/- 16 ppm
- Indium (In): 19 +/- 6 ppm
- Platinum (Pt): 39 +/- 24 ppm
- No other metals were detected in consumer goods mode.
Reading #2a) Clear silicone nipple
60-second reading
- Lead (Pb): non-detect
- Cadmium (Cd): 10 +/- 4 ppm
- Tin (Sn): non-detect
- Mercury (Hg): non-detect
- Selenium (Se): non-detect
- Barium (Ba): non-detect
- Arsenic (As): non-detect
- Chromium (Cr): non-detect
- Antimony (Sb): 13 +/- 9 ppm
- Niobium (Nb): 387 +/- 15 ppm
- Indium (In): 15 +/- 5 ppm
- No other metals were detected in consumer goods mode.
Please Note:
- It is typical for silicone products (even medical-grade silicone) to test positive for trace levels of Cadmium. I even have a category here on this website of items that are “Silicone with Trace Cadmium” — click here to see more examples.
- This level of Cadmium is considered safe by all standards.
- Given Cadmium is a known carcinogen (you can read more about that here, here, and here) if I were to have a baby today knowing what I know now based on the testing we do here at Lead Safe Mama, LLC — I would stick with a natural rubber nipple if my baby would tolerate it.
- If your baby will not tolerate a natural rubber nipple (and they refuse this) it is better to have a fed baby than a hungry baby and a silicone nipple should generally be fine (again, the levels — while not ideal — are generally safe by all current United States and European standards).

Hi! Thank you for the work you are doing. Have you found any plastic bottles that don’t have cadmium in the nipples? Thanks!
