How can you tell cooked king crab meat is bad?

Cooked king crab meat is bad if it has a sour or ammonia-like smell, which indicates spoilage. Additionally, check for any discoloration or a slimy texture; fresh crab meat should be firm and moist without being sticky. If it has been stored improperly or for too long, it's best to err on the side of caution and discard it. Always trust your senses—if it looks or smells off, it’s safer not to consume it.
