Is it safe to use lead-glazed pottery imported from Mexico for serving food?
No. Lead-glazed pottery sold at the border can leach dangerous amounts of lead into your food, especially when used with acidic ingredients.
What's actually in it
Many traditional pottery pieces use a glaze that contains lead. This is a heavy metal that does not belong in your body. When you use these items to cook or serve food, the lead can move from the glaze into your meal. This process is called leaching. It happens more easily when the pottery is exposed to heat or acidic foods like tomatoes, citrus, or vinegar.
What the research says
A 2026 study in the Journal of Public Health Management and Practice looked at glazed pottery sold at the Mexico-US border. The peer-reviewed research found that cooking acidic food in these vessels causes enhanced leaching of soluble lead. Because lead is a known toxin that can build up in your system, using these items for food preparation poses a clear risk to your health.
