Remember the horse meat scandal of early 2013? Now it's the fox's turn.

Wal-Mart stores in China have apologized for selling tainted "Five Spice" donkey meat after DNA tests concluded the product also contained fox meat. Donkey is a major part of Chinese cuisine in some regions.

Wal-Mart China CEO Greg Foran apologized and said the company would investigate its Chinese supplier, according to posts on China's Weibo social media.

The company has recalled the hybrid meat, and is offering to reimburse customers who have already purchased it.

This isn't Wal-Mart's first black eye in the Chinese market. The world's largest retailer has been fined for manipulating prices and selling expired meat in the past.

Food safety is a top concern for a country that has dealt with tainted baby formula and other dangerous food issues.
