Can the lion fish be poisonous to the consumer, the eater, if the spines are not removed properly? Are the spines venomous to the diver .. once the fish is dead? To a kitchen crew? I saw them on a menu and wanted to do my part by ordering it but was still a bit scared.
No, they are venomous, not poisonous. Just like you can eat rattlesnake without any harm. The spines can still cause injury after the fish is dead. Once they are clipped, the fish is completely safe to eat.
