The official Raspberry Pi power supply is not earthed, but provides its electrical safety by means of double insulation.
This means that if you touch conductive parts of the Raspberry Pi you may be providing a path to earth for a very small and safe AC current, particular if you are providing a good earth contact, for instance if you are barefoot on a stone floor, or touching another earthed electrical device.
To prevent it, wear shoes with rubber soles and don't touch any other electrical device. In any case, the double insulation of the power supply ensures that any residual current that may go through you to earth is well below the level that is considered a health risk.
