Vintage PRC Dezain Italy china dish: 11,000 ppm Lead on the food surface (on the decorative yellow & gold edging.)

Published: Sunday –  July 3, 2022

Given all federal agencies agree that there is no safe level of Lead exposure for humans, and also given that in 2008 the Consumer Product Safety Commission set the level of 90 ppm Lead as being the limit for allowable Lead in the paint, glaze or coating of an item intended for use by children – I would not personally be comfortable eating off of these dishes (and certainly would never let any child use one of these).

They may have been “safe” (determined by independent testing at the time of manufacture to be non-leaching for Lead) on the day they left the factory [although given the date of manufacture is unknown*, these dishes may be very old – and it is also possible they were made before any regulatory standards were put in place ], but there is no guarantee that over time, with age and use, they have not/will not become unsafe. This is especially possible if the item is used with with heated foods — or acidic foods, such as tomato-based sauces, vinegars, or lemon juice, for example. *I will update with any information about the date of purchase when I hear from the owner after publishing this post.

Now that we know for certain (using XRF testing) that there is a very high level of Lead in the glaze of this plate (see specific readings below), it is far simpler and less expensive to buy new dishes than it would be to send a dish like this to a lab to do leach-testing to confirm how much of the Lead might be leaching from the dish at this time (and under what conditions)… so many years after they were manufactured! Consequently – in adopting a #KnowBetterDoBetter philosophy and a guiding principle of not allowing any Lead in your kitchen (a great first step in making a safer home for yourself and your family) – I would recommend purchasing new dishes if you own these (and not using these for food use purposes at all). You can read more about these concerns specifically in this article – link.

Tamara Rubin is a multiple-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. 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 (and separate components) are each tested multiple times, to confirm the test results for each component tested and reported on. Please click through to this link to learn more about the testing methodology used for the test results discussed and reported on this website.
