2,312. What's Not a Treifa

Maachalos Assuros 4:11

If an animal is sick and weak, close to death, it is still permitted because it wasn’t injured in any limb or organ that would cause it to die. The Torah only prohibited cases that resemble an animal mortally wounded by a predator, i.e., injured by a blow leading to death.

Maachalos Assuros 4:12

Though permitted, the great Torah scholars wouldn’t eat from an animal that people rushed to slaughter before it died, even if it convulsed after slaughter. It’s not prohibited but one who accepts this stringency is praiseworthy.
