In a close call, Ms. Yang's mother in Hong Kong inadvertently stir-fried a red spot fighting crab that had been mistakenly mixed in with some cuttlefish. Fortunately, Ms. Yang utilized AI image recognition technology and identified that the crab contained a high concentration of tetrodotoxin—a potent neurotoxin that cannot be neutralized by high temperatures. Concerned about the risk of cross-contamination, she took immediate action by discarding the entire dish and thoroughly sterilizing the tableware, thus successfully preventing her family from being poisoned.

It's worth noting that seafood harvested near the shore often includes poisonous crabs, such as the demania cultripes and zosimus aeneus. Additionally, there are other venomous marine organisms like nassarius, conus, and the blue-ringed octopus, which can be extremely difficult to distinguish with the naked eye, posing a significant threat to those unaware of their dangers.
