Expert Guide To Non-Toxic Dinnerware | Lead-Free & Safe

What toxic materials can be found in dinnerware?

Lead and Cadmium

You might love the bright, vibrant colors and patterns on your ceramic dinnerware, but beware! Those eye-catching designs could be thanks to lead and cadmium in the glaze. These heavy metals can leach into your meals, especially if the dinnerware is old, damaged, or used with acidic foods. 

Exposure to lead and cadmium can cause serious health issues, particularly in children, including hindering brain development leading to learning disabilities, lower IQ, and behavioral problems. They can also cause nervous system damage, anemia, kidney damage, and increased cancer risk. 

BPA and BPS

Bisphenol A (BPA) and Bisphenol S (BPS) are chemicals used in some plastic dinnerware. These sneaky substances can leach out of the plastic and into your food, potentially messing with your hormones and causing other health problems. They have also been linked to obesity, diabetes, and even cancer.

PFAS

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals used to make dinnerware resistant to water, grease, and stains.

While that might sound convenient, these “forever chemicals” persist in the environment and can accumulate in your body over time. PFAS exposure has been linked to a range of health problems, including liver damage, thyroid disease, decreased fertility, high cholesterol, and cancer.

Melamine

Melamine is a type of plastic used to create shatter-resistant dinnerware. While it might seem like a practical choice, melamine can break down and release toxic compounds like cyanuric acid when ingested in large amounts. This nitrogen-rich compound has been linked to kidney stones and kidney failure, especially in children.

Silicone and Plastic

While silicone and plastic dinnerware are generally considered safe, it’s essential to make sure they’re made from food-grade materials.

Some cheaper plastic and silicone products may contain phthalates or other toxic additives that can leach into your food, especially when heated or used with acidic foods. Plastic can also break down over time, releasing chemicals into your meals.

PVC and Phthalates

Although it’s rare to find PVC in dinnerware, if you purchase from unreliable sources, there’s a slight chance your tableware might contain unauthorized or unsafe materials like PVC.

This type of plastic often contains phthalates and other toxic additives that can cause reproductive and developmental problems. Phthalates are endocrine disruptors, and PVC itself is considered a carcinogen.

How do these toxic materials make their way into our food?

The answer lies in a sneaky process called chemical leaching.

Chemical leaching occurs when chemicals from the dinnerware material migrate or dissolve into the food or drinks they come into contact with, that you ultimately ingest. 

Several factors can contribute to the chemical leaching process:

Heat: High temperatures from hot meals or microwaving can speed up the leaching process.

Acidity: Acidic foods and drinks are more likely to draw out chemicals from dinnerware compared to neutral or alkaline foods.

Time: The longer food sits in contact with dinnerware, the greater the chance of chemicals leaching.

Minimizing Your Exposure

Avoid Heating Certain Materials: If you’re unsure about your dinnerware’s safety, avoid using it for hot meals or microwaving it.

Be Cautious with Vintage Dinnerware: Vintage pieces may contain lead or other unsafe materials. Either avoid using them for food or have them tested for lead content.

Choose Non Toxic Materials: Opt for dinnerware made from materials with a low leaching risk, such as lead-free ceramic, glass, stainless steel, or food-grade silicone.

How can I tell if my current dinnerware is non toxic?

Check for lead and cadmium. Bright colors like yellows or reds, especially in older or vintage dishes, can be a sign of toxic heavy metals in the glaze. You can conduct a home lead or cadmium test kit on any suspicious dishes.

Inspect the glaze for cracks, chips, or uneven areas. If the glaze is damaged, lead and cadmium can leach into your food. Keep in mind that sometimes cracks may be too small to see at first if the dish has been dropped or hit something hard.

Look for labels indicating the dishes are lead or cadmium-free. Many modern dishes intended for food use will display such markings.

Consider the age of the dishes. Ceramics made before the 1980s may have used lead-based glazes, posing a health risk, Dishes made in sweatshops may also be under-fired to save time and fuel, compromising safety.

Avoid using dishes with deep divots or scratches that can gather food and bacteria if not cleaned thoroughly.

Purchase dinnerware from reputable brands that adhere to safety standards and test their products for toxins.

How can I clean and care for my non toxic dinnerware?

Stainless steel is generally quite durable and easy to clean. You can wash it with warm, soapy water and a soft sponge or dishcloth. For tougher messes, you can use a baking soda paste or a mild dishwashing liquid. Avoid using harsh chemicals or abrasive scrubbers, as these can scratch the surface.

Ceramic is also relatively durable, but it’s important to handle it with care to prevent chipping or cracking. You can wash ceramic dinnerware by hand or in the dishwasher (check the manufacturer’s instructions first). If washing by hand, use warm, soapy water and a soft sponge. Avoid using extreme temperatures, as this can cause the ceramic to crack.

Glassware is another easy-to-clean option. You can wash it in the dishwasher or by hand with warm, soapy water. Avoid using abrasive scrubbers or harsh chemicals, as these can scratch the glass.

More General Tips

• Rinse your dishes with warm water before washing them to remove any food scraps.
• Allow your dishes to air dry completely before storing them. This will help prevent the growth of bacteria.
• If your dishes become stained, you can try soaking them in a solution of warm water and baking soda or white vinegar.
• Avoid using abrasive cleaners or sponges, as these can scratch the surface of your dishes.
• Store your dishes in a cool, dry place.
• With proper care, your non toxic dinnerware should last for many years. For specific care instructions,  always refer to the manufacturer’s recommendations for your dinnerware.
