Those ubiquitous signs, “Employees Must Wash Hands” probably don’t have the desired effect. Jon Stewart says, they sure ain’t keeping the piss out of your Happy Meals.

Some people have told us images like the one below, are too graphic and will offend people. Maybe. I’m offended that people don’t wash their hands which can lead to other people barfing and spreading things like the H1N1 virus. The U.S. Centers for Disease Control seems to agree, and has called for new food safety messages using new media.

So with all those germ factories … I mean students … returning to the confined quarters of residence living, here’s some tips for not barfing:

• Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.

• If you are sick with flu-like symptoms, stay home for at least 24 hours after your fever is gone. Keep away from others as much as possible.

• Wash your hands often especially after you cough or sneeze.  Alcohol-based hand cleaners are also effective, but are best used after proper handwashing.
