Apple said on Friday morning Australian time it was voluntarily recalling AC wall plug adapters designed for use in Argentina, Australia, Brazil, Continental Europe, New Zealand and South Korea.

The affected two-prong adapters could, in very rare cases, break and create the risk of an electrical shock if touched, the company said in a blog post.

The company said it was aware of 12 such incidents worldwide.

The affected adapters were shipped with Mac and certain iOS devices between 2003 and 2015 and were also included in the Apple world travel adapter kit.

Apple said the recall does not affect AC wall plug adapters designed for Canada, China, Hong Kong, Japan, United Kingdom, United States or Apple USB power adapters.

Apple shares were down about 0.2 percent in morning trading, in line with the broader market.
