I have hosted some holiday celebrations, notably the 4th of July (AKA Independence Day in the US). The plates were metallic silver, blue and red. And the guests who I served grilled chicken to have not turned blue.
I am confident that (despite lack of FDA oversight of production) these plates are safe to serve human food upon.
