This requirement is not applicable if the manufacturer specifies size and shape of metallic
containers suitable for microwave cooking.
2. Microwave cannot penetrate metal, so metal utensils or dishes with metallic trim should not be
used.
3. Do not use recycled paper products when microwave cooking, as they may contain small metal
fragments which may cause sparks and/or fires.
4. Round /oval dishes rather than square/oblong ones are recommend, as food in corners tends to
overcook.
5. Narrow strips of aluminum foil may be used to prevent overcooking of exposed areas. But be
careful don’t use too much and keep a distance of 1 inch (2.54cm) between foil and cavity.
The list below is a general guide to help you select the correct utensils.
