Zinc is a natural element critical to human health and it can be found in many foods and multivitamins. How safe is it when used as a surface material in your home, restaurant or business?
Zinc, on it's own, is not toxic unless you consume high doses of it. Many foods have naturally occurring zinc and it is recommended that diets include 8 to 11 mg of zinc. You may have also used it on your skin as a sun block or taken it in lozenge form to fight a cold.
When considering zinc as a long lasting surface material in your home or hospitality project, keep in mind that most food preparation doesn't happen directly on the surface. Can you cut a slice of bread directly on the surface - sure, and you may leave a scratch that is likely to be unnoticeable within a day. Is it better to use a cutting board? Yes, for the food and the knife. Can you eat food that has been directly on the countertop? Yes, but don't throw out your plates.
Your body does not store zinc which is why a daily dose is recommended. It is possible to have a deficiency as well as too much zinc. If you are concerned about this, we recommend you do further research. It is NOT our intention that a person would derive their recommended daily allowance from their countertops. We just want to be clear on that.
