Substituting one type of animal meat for another is always a big no-no, but we're not sure we've ever seen this particular mix-up. Walmart has been forced to issue a recall of its signature "five spice" donkey meat in China, because they mega-retailer found it was tainted by DNA from other animals, possibly fox.

Walmart China's "fox in your donkey meat" scandal has been brewing ever since the Shandong Food and Drug Administration said Walmart's donkey product contained fox. Walmart didn't confirm or deny the regulators' claims, but they did say they found traces of DNA from other animals that weren't donkeys in their donkey meat.

"We are deeply sorry for this whole affair," WalMart China's Greg Foran said in a statement. "It is a deep lesson that we need to continue to increase investment in supplier management," he added. The Telegraph reports that customers who bought the fox-laced donkey meat will be issued reimbursements.

This recall brings up some basic questions like: What else is Walmart selling that we don't know about ? What does donkey meat taste like? What does Walmart's donkey meat taste like? Could anyone actually taste the fox?
