Which of the following best describes metallic food poisoning?

• A. Foods stored in metal containers
• B. Drinking water with metal ions
• C. Acidic foods or drinks in contact with copper or zinc
• D. Cooking in metal pots

Answer: (C)

Metallic food poisoning happens when metal ions migrate into food from reactive metal surfaces, especially under acidic conditions. Acidic foods or drinks can corrode metals like copper or zinc, causing these metals to leach into the food. That leaching can give a metallic taste and, if enough metal is ingested, pose a toxic risk. This is why the best description is acidic foods or drinks in contact with copper or zinc—it directly explains both the mechanism (corrosion and ion migration) and the specific metals involved.

Storing foods in metal containers or cooking in metal pots can involve metal contact, but the key risk for metallic poisoning is the combination of acidity with reactive metals, which is why those other options aren’t the most accurate description. Drinking water with metal ions is a different exposure pathway and isn’t the food-specific scenario described here.
