Why's that?

Barracuda is one of the primary carriers of ciguatera poisoning in tropical reef environments. In a nutshell, ciguatera is a micro organism that lives on certain corals and sea weeds found in tropical environments. When the coral and weed gets eaten by reef fish, the toxin they produce enters the food chain and, through bio magnification, eventually when humans eat barracuda, grouper etc. it causes a terrible disease which can last for a very long time.

Not all predatory fish carry the toxin, even when caught in environments where ciguatera is present, but it's definitely not worth the risk. As a general rule, it's safer to stay away from reef predators caught in tropical habitats.
