Why can groupers be eaten if they are poisonous?
Groupers are toxic, but they can be safely consumed as long as parts with higher toxin levels are avoided. Generally, poisoning does not occur under normal eating practices. The detailed explanation is as follows:
Marine algae in the sea are toxic. Groupers are carnivorous fish that primarily feed on small fish, which in turn consume toxic algae. When groupers continuously eat these small fish over time, toxins from the algae accumulate in their bodies, making the groupers themselves potentially toxic. However, during regular consumption, people typically do not eat the stomach or intestines of the grouper, and other high-toxin areas are also avoided, so poisoning is unlikely. It should be noted that parts such as the head, eggs (roe), skin, and internal organs of the grouper may contain toxins and are not recommended for consumption.
If any discomfort occurs after consumption, individuals should seek medical attention promptly and receive standardized treatment under a doctor's guidance to promote recovery.
