It's already been demonstrated with chocolate sauce.
I don't blame the hospital for failing to train and follow the right protocols. It's not reasonable for every random hospital in the US to be prepared to go Full Ebola at the drop of a hat. That's the CDC's job.
But I do blame the CDC for not flying in a team of specialists to ensure that the random hospital that caught a surprise case of Ebola did follow the right protocols from the start. The fact that only health workers have been infected so far is not an endorsement, but an indictment, of the CDC's strategy.
