Affected plugs are white, have no letters on the inside slot and were produced and shipped between 2003 and 2010.
Six incidents have been reported, Apple said.
This is not the only recall the Cupertino company is conducting at the moment; in Continental Europe, Australia, New Zealand, Korea, Argentina and Brazil Apple is collecting two-pronged adapters which reportedly suffered from the same issue.
The three-pronged plugs, primarily used in the UK, Hong Kong and Singapore, were sold with Mac computer and mobile devices between 2003 and 2010, as well as part of the Apple World Travel Adapter Kit.
The recall covers only the three-pin BS 1363 plug heads, used in the UK, Hong Kong, and Singapore, and none of the other worldwide designs, and covers a design defect which 'in rare case' can damage the plug in such a way as to expose the user to live mains voltages.
Apple has announced a recall of United Kingdom plug adapters after confirming that they can break and cause electrical shock.
