Introduction:

Tamara Rubin is an independent advocate for consumer goods safety, and she is also a mother of Lead-poisoned children. 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. She uses XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for metallic toxicants (including Lead, Cadmium, Mercury and Arsenic).

The test results of most of the consumer goods shared on this website are most often testing done on items that have been sent in by my readers for testing and reporting. This is a collaborative effort (with my readers) to help you make informed decisions for your family (so you can have an idea of what to look for – and what you might want to avoid – in making safer choices for your home.)
