Answer 1

The trays are antimicrobial in the same sense that enhanced airport security makes planes safe, weapons free zones.

TSA has a 5% tested detection rate for weapons. The trays have stuff in them that prevent (some) microbial growth.

But both are heavily marketed as necessary and effective.
