The main hygiene issues with ceramic tableware are excessive lead and cadmium leaching. These heavy metal elements may exist in the glaze and decorative patterns of ceramic tableware, and when used to hold food, especially acidic food, they can cause heavy metals to dissolve into food and enter the human body, posing a potential threat to health.
Specifically, ceramic tableware may contain heavy metals such as lead and cadmium in the glaze and decorative patterns during the manufacturing process. If used to hold food, especially acidic food, it can cause lead and cadmium to dissolve into the food and enter the human body. Lead and cadmium are heavy metal elements that are not easily excreted in the human body. Long term consumption of foods containing lead and cadmium can have an impact on the immune system and may lead to various diseases, including arteriosclerosis, kidney atrophy, nephritis, etc.
