Ciguatera poisoning is caused by a toxin found in certain large predatory reef fish. Which fish is a common source?
a.Barracuda and large grouper
b.Atlantic cod
c.Canned sardines
d.Farm-raised tilapia
解析
Ciguatera toxin accumulates in large predatory reef fish such as barracuda, amberjack, and large grouper; the toxin cannot be destroyed by cooking or freezing. Buying fish from approved, reputable suppliers is the main control. Farmed tilapia, cod, and canned sardines are not typical ciguatera sources.
