Consumption of seafood and preterm delivery

When we scanned Yasuo Ishida's faxed letter “Method of cooking should be named” into our electronic system, two errors were introduced but not noticed (25 May, p 1279). In one case, a letter was wrongly inserted, and in the other a number dropped off. The sentence “Or [are we to] eat raw sashimi with snake?” should have read “with sake” (the Japanese fermented alcoholic drink made from rice). The correct zipcode for the author has a 7 in it (MO 63117).
