Contaminated fish can also cause ciguatera fish poisoning. This type of food poisoning happens due to ciguatoxin, a toxin found in tropical waters. According to stats, as many as 50,000 individuals who live in tropical areas get ciguatera fish poisoning every single year.
The worst part? Normal cooking temperatures can’t destroy this toxin.
On the other side, shellfish can be as harmful as fish when it comes to food poisoning. Still, store-bought shellfish are safe to eat. So, it would be best to consume store-bought shellfish from now on. Plus, you should make sure that fish is cooked through and mussels, oysters, and clams until their shells open.
P.S.: If the shells of some oysters won’t open, throw them.
