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. 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. Her work was also responsible for two CPSC product recalls in the summer of 2022, the Jumping Jumperoo recall (June 2022) and the Lead painted NUK baby bottle recall (July 2022) and was featured in an NPR story about Lead in consumer goods in August of 2022. 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 and reported on.

This is my plate and OH EM GEE !!! My grandparents gave the full set of these to my parents, probably before I was born. (I am 63.) These were our “good” plates and so, fortunately, it seems, were rarely used during my childhood. When my parents retired, however, and bought a house on Cape Cod, they used them full time there. I was there every summer 2007-2010 and full time 2011-2013, eating off of these plates.
I am going to get rid of these plates (in the trash) but feel horribly now for donating the other half of the set, plus serving plates (though they were white inside) and a tea pot, all part of the set, five years ago.
Is there any chance that the lead and other toxins don’t leach into the food?
I am so very glad I sent this to you, Tamara. Thank you so very much.
