This ceramic “Threshold” brand (made in Portugal, for Target) terracotta appetizer/ olive/ salsa dish was positive for Lead at levels as high as 4,000 parts per million (ppm) when tested with an XRF instrument in 2018.
This is remarkable (and a good example to share), because it is important to make the distinction between the plain white ceramic Threshold pieces and ones like this, which have an orange-y terracotta base and are coated in a thicker white glaze.
The plain white Threshold pieces (with a white ceramic base) have consistently tested negative for Lead (non-detect/ Lead-free) or Lead-safe (below 90 ppm Lead); however, I was not surprised when this piece tested positive — for three reasons:
#1) most “Made In Portugal” items I have tested have been positive for at least some amount of Lead in the glaze, and
#2) even newly-manufactured items — that have this “handmade” look (vs. the more common “mass-manufactured”/ “refined polish” look of the white china or ceramic Threshold items) — are more likely to test positive for Lead, and
#3) while terra-cotta style base clay can be Lead-free (or low-Lead), most glazed terracotta pieces I have tested (regardless of the country of origin) have been positive for Lead in the glaze (usually at very high levels). A good example of items like this that are consistently high-Lead are glazed terra-cotta planters (that you might buy at a typical gardening store).

It’s also a myth that “plain white items are less likely to test positive for Lead.” Plain white can be as high-Lead (and sometimes even higher Lead) than some decorated items — “Lead White” is an actual commercial base-color for pigments. To see more white ceramic items I have tested, CLICK HERE.
Levels above 90 ppm Lead (in the paint, glaze, or coating of an item) are considered unsafe (and illegal) in newly-manufactured items intended for use by children. Dishes however, are not regulated for total Lead content as detectable with an XRF instrument, and as such, are not considered illegal in any way when high in Lead levels. (Dishes are generally not considered “items intended for use by children” unless they are dishes specifically made and sold as “infant” dishes, “toddler “dishes, or similar.)

Hi Tamara. Are plastic plant pots generally lead-free? If I replace all my glazed terra cotta pots I want to know I’m not just trading one problem item for another. Thanks.
Renee Vogel says
Thank you for your commitment to health and safety! I am trying to sprout chia seeds on Terra Cotta and am wondering what you would recommend?
Tamara says
Hi Renee,
Unglazed terra cotta is normally Lead-free.

Why then are Saltillo tiles high lead when a lot of them come unglazed?
Tamara says
I am not familiar with those tiles.
