We continue looking at the cookware you use to raise awareness of the health risks associated with their use.

Ceramic, Enamel and Glass

The only health concern about using glassware or enamelware comes from minor components used in making, glazing, or decorating them, such as Some glazes contain lead or cadmium - substances which are poisonous.

Cookware sold in Australia usually has to comply with strict regulations to prevent pieces releasing these dangerous substances into food. Be cautious of ceramic materials bought from overseas - some places do not enforce the same regulations on lead and cadmium. You should also refrain from bringing decorative ceramics in contact with food.

Plastics

Caution should be exercised when using plastics to store food and cook with. Some plastics are not suitable for contact with food, so be careful to use only containers made from food grade plastics when reusing old plastic containers.

When plastics are heated to high temperatures, for example when used in the microwave, there is a chance that food may absorb the material that makes it flexible. Avoid bringing oily or fatty foods in contact with plastic wrap at high temperatures.

Nonstick coated cookware

Many nonstick coatings are manufactured with a chemical called perfluorooctanoic acid (PFOA), which has been found to be a likely carcinogen based on laboratory tests on rats. PFOA does not remain in the coatings after manufacture, and the use of non-stick cookware and utensils shouldn't increase your exposure to PFOA. Personally, I steer clear of them however.

Nonstick heated to temperatures greater than 350°C can give off poisonous fumes. Such temperatures are not likely to be reached with appropriate use.

Another drawback with using nonstick cookware is that you can't give them a good ol' scrub, b/c you risk damaging the coating.

Silicone Cookware

Cookware made from silicone rubber is an alternative to older style nonstick cookware. As well as being nonstick, it is also stain-resistant, robust, tolerates extremes of temperature, and cools quickly. Silicone cookware will is non-reactive, and does not produce any hazardous fumes. There are no known health hazards associated with its use.
