Tamara Rubin is a multiple-federal-award-winning independent advocate for childhood Lead poisoning prevention and consumer goods safety, and a documentary filmmaker. She is also a mother of Lead-poisoned children (two of her four sons were acutely Lead-poisoned in 2005).
- 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 five 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!
