What type of poisoning can result from improperly prepared fugu?

• A. Toxin-induced paralysis (tetrodotoxin poisoning)
• B. Hemolytic anemia from toxic fish consumption
• C. Acute gastrointestinal infection
• D. Neurotoxic shellfish poisoning

Answer: (A)

Fugu, or pufferfish, contains a potent neurotoxin known as tetrodotoxin. This substance is responsible for causing toxin-induced paralysis in cases of fugu poisoning. Tetrodotoxin works by blocking sodium channels in nerve cells, which leads to symptoms such as numbness, paralysis, and respiratory failure if ingested in sufficient quantities. The risk arises when fugu is not properly prepared, as the toxin is concentrated in certain organs and tissues of the fish, making it essential that trained chefs handle its preparation with extreme caution.

The other potential options relate to different types of poisoning or health issues. Hemolytic anemia is not associated with fugu but rather with different toxic fish or environmental factors. Acute gastrointestinal infections generally result from bacterial or viral pathogens rather than toxins present in fish. Neurotoxic shellfish poisoning is associated with certain shellfish contaminated with harmful algae, not with fugu specifically. Therefore, the connection of tetrodotoxin to fugu as a cause of toxin-induced paralysis makes it the correct answer.
