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.
