At the end of the James Bond novel From Russia with Love, Rosa Klebb actually manages to poison Bond at the end of the novel with fugu on a small blade in her boot. The immediately following novel, Doctor No, actually explains that it's fugu, or tetrodotoxin. This novel was written in 1958, and fugu wasn't exactly well known ("Trust the Russians to use something no-one's ever heard of before" say Sir James Malony, a neurologist looking after Bond as he recovers), although it is mentioned again in the novel You Only Live Twice.
(The scenes in the film of Dr No about Bond changing his weapon to a Walther, due to his Beretta jamming and a woman nearly killing him is actually a reference to the novel of From Russia with Love, but when that novel became the second Bond film, the ending was obviously changed, as no doubt film audiences didn't want the film to end on a cliffhanger with Bond dying from fugu poisoning)
