Kitchen toxins, especially Teflon, are very toxic. Stainless steel is probably the best to avoid toxin production. Hydrogen peroxide and vinegar are a great combination to sterilize cutting boards and other kitchen surfaces. Baking soda is a great kitchen cleansing agent. Lead in dishware is a concern because it is often in the glaze, especially in products made in China. Lead crystal is another source of lead, particularly if liquids are stored overnight or longer.
