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.

We bought a galvanized bucket to use for “glögg”. a swedish alcoholic beverage
http://sv.wikipedia.org/wiki/Glögg (unfortently not avaliable in english but the poctures might get you an idea)

Basicly we let spices, a special type of soda close to beer and sugar mix together and stay for 4 weeks in it.
Should we be worried?

I am thinking of using galvanized steel flashing to convert my weber grill to a pizza oven. I suppose the temp could get upwards of 700 degrees ... Is it safe to cook a pizza

Hi Patty,

If you are worried about the acidity of the foods on the serving trays, laying a piece of foil down under the food would be a good way to ensure the food remains safe. Even if you decide not to use foil, I don’t think you will have any issues with anyone getting sick since the food will be in contact for a short amount of time.

I do special events, and I purchased this 3 tier galvanized serving tray I was hopeing to use to put like onions, pickles etc…. but now I’m afraid to after reading this.  If I put foil over the top of these trays would it help and I would not have to worry about the possibility of no one getting sick?
Thank you for your help in this matter.
