A while back the Clorox Company funded a study called, “Germs in the Workplace.” From WebMD, here is the list, from the most to least germs on work space surfaces:
Teacher
Accountant
Banker
Radio DJ
Doctor
Television producer
Consultant
Publicist
Lawyer
The survey reports “Surfaces regularly used by teachers, accountants, and bankers harbored nearly two to 20 times more bacteria per square inch when compared to other professions.”
