Is it safe for food to be in contact with galvanized steel?
For most foods, contact with galvanized steel is perfectly safe. Only acidic foods should not come in contact with galvanized steel according the the U.S. Food & Drug Administration. The acid in some foods reacts with the zinc coating to form salts that are readily absorbed by the body and in excess could cause a very mild sickness. So, where is galvanized steel used in food production operations? There are two primary and distinct areas, for the structural supports of a building, such as a bakery or slaughterhouse, and for trays, racks, conveyor, freezers, refrigerators, and counter-tops in direct contact with the food. Qualifying all of this discussion is the fact zinc is a necessary part of our RDA, approximately 15 mg should be a part of your daily intake.
