Ricin is classified as which type of toxin?

• A. Endotoxin
• B. Neurotoxin
• C. Enterotoxin
• D. Mycotoxin

Answer: (B)

Understanding toxin classification and mechanism helps explain why ricin fits best with a neurotoxin label. Ricin blocks protein synthesis by inactivating ribosomes, causing rapid cell death across multiple tissues. This broad systemic damage can include effects on the nervous system, leading to neurological symptoms after exposure. It is not an endotoxin (which are bacterial LPS components), nor an enterotoxin (which targets the intestinal tract), nor a mycotoxin (produced by fungi). Among the given categories, ricin’s potential to disrupt neural function and cause systemic toxicity makes neurotoxin the most appropriate classification.
