What risk is associated with using galvanized metal for food storage?

Using galvanized metal for food storage presents a risk primarily because it can leach harmful chemicals into food. Galvanization is a process that involves coating steel or iron with zinc to prevent corrosion. However, when galvanized metal comes into contact with acidic or alkaline foods, the zinc can dissolve and contaminate the food. Zinc is not considered safe in high amounts and can lead to health issues if ingested.

Additionally, this risk is heightened if the metal is old, has been scratched, or is otherwise compromised, which can increase the likelihood of leaching. It is crucial for food safety to use materials that do not pose a contamination risk, particularly in environments such as food storage where maintaining hygienic conditions is paramount.
