What causes toxic-metal poisoning?

Toxic-metal poisoning is primarily caused by leaching, which occurs when certain metals from utensils or equipment migrate into food. This can happen with metals such as lead, copper, or aluminum especially when using cookware that is not designed for food safety. Factors such as high acidity or temperature can increase the likelihood of this leaching process, resulting in harmful levels of metals entering the food.

In contrast, overcooking food may affect texture and flavor but does not directly lead to metal poisoning. Food expiration primarily concerns spoilage and foodborne pathogens rather than toxins from metal sources. Inadequate refrigeration mainly risks the growth of bacteria and does not involve the leaching of heavy metals. Understanding how materials interact with food is essential in preventing toxic-metal poisoning in food handling practices.
