In 2002, Jon Stewart quipped while hosting Saturday Night Live,

“If you think the 10 commandments being posted in a school is going to change behavior of children, then you think “Employees Must Wash Hands” is keeping the piss out of your happy meals. It’s not.”

Apparently the signs aren’t working in Ontario hospitals either.

Jim McCarter, the province’s auditor general, said in a report tabled in the provincial legislature that the results of a hand-hygiene program piloted in 10 hospitals revealed personnel were complying with the rules of good hand hygiene only 40 to 75 per cent of the time.

Time for new messages.
