Ciguatera fish poisoning onset occurs within which timeframe after ingestion?

Onset timing for ciguatera fish poisoning is typically within hours after eating contaminated reef fish, usually within a window of 1 to 48 hours. This reflects how the toxin is absorbed and starts causing symptoms soon after ingestion. Cooking does not destroy these toxins, so the timing isn’t about whether the fish was cooked but about when the toxin takes effect in the body. Early gastro‑intestinal symptoms—nausea, vomiting, diarrhea—often appear first, with neurological effects such as tingling, numbness, or altered hot/cold sensation developing within the first day or two. That pattern fits the 1–48 hour window best, while immediate onset or delays of several days to a week are not typical for this illness.
