Is it acceptable to store food in copper or zinc coated containers?

Storing food in copper or zinc-coated containers is not acceptable due to the potential health risks associated with these metals. Copper and zinc can react with certain types of food, especially acidic foods like tomatoes or citrus. This reaction can lead to leaching of the metals into the food, resulting in food contamination and possible metal toxicity. Therefore, it is crucial to use food-safe materials that do not pose a risk to health when storing food.

While some options suggest safety under certain conditions, such as being properly lined or only for short-term storage, these do not mitigate the inherent risks associated with using unlined metals for food storage. Correct food safety practices prioritize the safety and well-being of consumers, hence making the outright rejection of copper or zinc-coated containers essential.
