Utensils must be fabricated in such a way that there are no traces of poisonous metals, such as zinc or lead,
that could come in contact with food. At one time copper and brass were commonly used for cooking
utensils. The weight and und-keep of equipment made from these materials have made them unsatisfactory
for institutional use. Enamel chips and cracks easily and is not suitabale for heavy-duty kitchen equipment.
Only plastic containers that have been officially certified for use with foods should be use.
