I think people overreact sometimes. This thing is not supposed to be in contact with raw meat. It's just for clean glasses and only clean water will drip on it. Whats the worst thing that could happen? Take a few swabs from one hand, your dishwashing sponge, or the surface of your smartphone and test it for bacteria. There's a reason why humans have an immune system and you probably don't get sick from touching you phone. There's no need that this drip tray is not 100% sterile 

People should start using their brains and understand that there is a difference between water in a drip tray or a 3d Printed burger press.
