You know the kitchen at home is clean (sort of), but what about the tables you eat at when dining out?

ABC News decided to investigate which items on a restaurant table are the dirtiest, and the answers were . . . obvious.

Researchers from the University of Arizona swabbed common tabletop items for germs, including salt and pepper shakers, ketchup, menus, and sugar.

-Sugar clocked in at the lowest average bacteria count, with 2,300 organisms.

-Ketchup, mustard, and salt all fell generally in the middle.

-Pepper is second-highest on the list, with nearly 11,600 organisms.

-Menus top the list with a whopping 185,000 bacterial organisms.
