Ruling on eating meat slaughtered by electric shock or strangulation?

Some countries slaughter chickens by electric shock or strangulation. How should a person act if he finds no other option? May he eat from them?
No, this is carrion.
Q: And is it necessary for this to be established for him?
A: If it is from the slaughter of the People of the Book, it is permissible for him, unless it is established for him that it was slaughtered contrary to the Shari'ah, such as by electric shock or otherwise. However, if it is from the slaughter of the Zoroastrians or the polytheists, this is forbidden absolutely.
