I'm going to give you the answer.
It's not pork: had it been pork, the meat would have looked a bit more pinkish. It's true that chorizo is red, but it's due to the addition of paprika.

It's not Mammoth nor E.T., indeed Both of them disappeared a long time ago.
Nor it is ostrich, even if its meat is also a bit red.
This is donkey meat. Maybe some of you are eating such food. I've been a bit mistaken since Islam forbids donkey meat, as well as dog, cat, monkey, lion, elephant... except wild donkeys, as mentioned in the hadith of Abou Qatâda.
