You might assume the airplane bathroom is the dirtiest place in the sky. After all, that’s a passenger’s number one and number two choice for waste disposal. Plus, loose condoms imply there were trouser snakes on a plane spitting their love venom at some point. So it seems like a pretty safe bet that people were joining the Mile-High Club in the bathroom before those condoms gots deposited in a seat pocket. But you can just flush that assumption down the toilet because according to Forbes, the bathroom ain’t it. It gets cleaned regularly because so many unsavory things happen there. Instead, the nastiest place is where the most savory things happen, savory things like eating.

Turns out the seatback tray tables on a plane carry the most bacteria. Travelmath had a microbiologist “collect 26 samples from five airports and four flights” and uncovered that the place where you sit your in-flight meal had more than eight times as many bacteria colony forming units per square inch as the bathroom. As Time  details, the bite-sized nastiness lurking on tray tables includes “cold viruses, human parainfluenza viruses, norovirus (which can cause diarrhea and vomiting) and the superbug MRSA, which causes skin infections.” So, bon appetit? Or if you prefer the dirtiness of the bathroom, boner appetit.
