Man Decapitates Another, Remaining Mysteriously Snake-like in the Act
A recent incident in Guangdong Province, China, has highlighted the potential danger of handling decapitated snakes, particularly when preparing food. Chef Peng Fan, during the process of preparing braised snake soup, was bitten by the head of a decapitated Indian cobra, ultimately leading to his tragic death [1][3].
The incident underscores the importance of proper handling and safety precautions when dealing with venomous snakes. Snakes, unlike mammals, can survive for a significant period after decapitation due to their slower metabolism [2]. This allows their brain tissue to remain alive and functional for longer after blood flow stops, a factor that contributed to the lethal potential of the decapitated head in this case.
Species like cobras have been observed to exhibit nerve activity that can persist for up to an hour or more after the head is severed [2]. This residual nerve firing can cause the decapitated head to bite reflexively, posing a real danger to anyone handling it [1][2][4]. There are documented cases of fatal bites from decapitated heads, illustrating the lethal potential of these reflex bites [3][4].
The muscles and nerves in the head can respond to stimuli, including triggering a venomous bite reflex, even without the brain fully functioning [2]. However, it is important to note that this is not the snake head being "alive" in the full biological sense, but rather a result of basic neurophysiology where the nervous tissue can remain responsive briefly after loss of central control.
The duration a snake's head remains alive depends on the environment's temperature. If the venom glands, nerves, and the muscles used for biting and injecting venom are not damaged, a snake's head can still bite [2]. This serves as a reminder that snakes can survive for a significant period after decapitation, and caution is strongly advised around decapitated snake heads, as they can still cause harm despite the snake being technically dead.
Experts, such as Wolfgang Wuster, a herpetologist at Bangor University, and Lee Fitzgerald, a herpetologist at Texas A&M University, have commented on the incident. Wuster stated that this is a rare incident due to the slower metabolism of snakes and reptiles [2].
In conclusion, the incident involving Chef Peng Fan underscores the potential danger of handling decapitated snakes and the importance of proper handling and safety precautions when dealing with venomous snakes.

In light of the incident in Guangdong Province, it is crucial to understand that snake heads can remain active and potentially dangerous for a considerable period after decapitation, especially in the case of venomous species like cobras. Therefore, implementing proper handling and safety precautions when dealing with such snakes in medical-conditions, health-and-wellness, or for culinary purposes is of utmost importance to prevent accidents and preserve health.
