For those new to the Lead Safe Mama website:

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 in 2024! Please check out our press page to see some of the amazing coverage of our work so far this year!

How much Lead is “too much” Lead?

For context, the amount of Lead considered unsafe in an item intended for use by children is anything 90 ppm Lead or higher in the paint, glaze, or coating of an item and/or anything 100 ppm Lead or higher in the substrate. Unfortunately (as discussed in many articles here on the Lead Safe Mama website) there is no law limiting total (XRF-detectable) Lead content in dishes or cookware (or really in any consumer goods not expressly “intended for use by children”). For a detailed discussion about the concern for Leaded glaze on new or vintage dishware, click here.
