Narrated Az-Zhuri: regarding an animal, e.g., a mouse or some other animal that had fallen into solid or liquid oil or butter-fat: I had been informed that a mouse had died in butter-fat whereupon Allah's Messenger (ﷺ) ordered that the butter-fat near it be thrown away and the rest of the butter-fat can be eaten.

حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنِ الدَّابَّةِ، تَمُوتُ فِي الزَّيْتِ وَالسَّمْنِ وَهْوَ جَامِدٌ أَوْ غَيْرُ جَامِدٍ، الْفَأْرَةِ أَوْ غَيْرِهَا قَالَ بَلَغَنَا أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَمَرَ بِفَأْرَةٍ مَاتَتْ فِي سَمْنٍ، فَأَمَرَ بِمَا قَرُبَ مِنْهَا فَطُرِحَ ثُمَّ أُكِلَ، عَنْ حَدِيثِ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ.
