Final answer:
Signs of ciguatoxin (seafood toxin) include neurological symptoms such as nausea, vomiting, abdominal pain, rash, fever, malaise, breathing difficulties, memory loss, confusion, dysentery, watery diarrhea, fever, chills, and abdominal cramps.
Step-by-step explanation:
Signs of ciguatoxin (seafood toxin) include neurological symptoms such as nausea, vomiting, abdominal pain, rash, fever, malaise, breathing difficulties, memory loss, confusion, dysentery, watery diarrhea, fever, chills, and abdominal cramps.
Ciguatoxin is produced by certain types of dinoflagellates, such as Gonyaulax, Alexandrium, and Pfiesteria piscicida. When these dinoflagellates become dense and cause harmful algal blooms, seafood can become contaminated with ciguatoxin. When humans consume contaminated seafood, they can experience the symptoms mentioned above.
It is important to avoid consuming seafood known to harbor ciguatoxin, and to regularly monitor and shut down contaminated shellfish beds to prevent human exposure to this toxin.
