The following was a "Brief report" in the JAMA, Feb. 15, 1985 (vol. 253, #7) pages 1012-1013. "From 1969 to 1984, we treated 178 patients with acute gastric anisakiasis caused by gastric mucosal penetration of the Anisakis larvae. Because the larvae of Anisakis can always be observed by endoscopy and removed with biopsy forceps, early performance of endoscopy is highly recommended for patients who have eaten raw fish within 12 hours of onset of the gastric symptoms. Endoscopic removal is essential to relive the intolerable pain; after relief, the administration of antacids will repair the damaged gastric mucosa. Ulcer formation is rare" For the full report (the above was only an abstract), see the issue. A few notes: The authors state that mackerel and horse mackerel were believed to be "primarily responsible". Also, few were observed between June and November (EAT NOW!) Also, the authors are Japanese, so the fish may vary. HOwever, there have been reports in the US (they cite: AM J. Trop. Med. Hyg, 1983). So, in conclusion, there's good news and bad news. The bad news is there's a chance of getting painful worms, the good news is (1) it seems to have a low probability and (2) it doesn't lead to permanent damage. Yes, I continue to eat sushi fanatically. Mark.
