If you’re even minorly germ-aware, the airport likely horrifies you; thousands of people — who may or may not have washed their hands — touching the same things that you too have to touch.

And while most people probably consider an airport’s heavily-used toilet to be the worst offender, a study by pandemic experts from the University of Nottingham found that the plastic bins at airport security checkpoints carry the most germs — even more than toilets. The Federal Aviation Administration processes 2.6 million airline passengers each day, which means every day 2.6 million passengers are putting their shoes, loose change, and cell phones in bins that are then passed back down the line to be used again and again.

With statistics like this, it’s welcome news that antibacterial checkpoint trays are being rolled out to more than 30 U.S. airports this summer. The trays, which were supplied by Florida’s SecurityPoint Media, are treated with an antimicrobial substance that inhibits bacteria growth.

“Each tray has 100% antimicrobial protection,” Joseph Ambrefe, CEO of SecurityPoint Media, said to The Points Guy. “The additive is imbedded in the manufacturing of the tray as well as the substrate on each tray. And the antimicrobial protection will not wear off or fade away.”

The Points Guy reports that new bins have already been delivered to Denver (DEN), Knoxville, Tennessee (TYS), Minneapolis/St. Paul (MSP), Nashville, Tennessee (BNA), Tampa, Florida (TPA), Washington Reagan National (DCA), and the Northwest Arkansas Regional Airport (XNA). Another 15 airports will be supplied with the bins by early July.
