Erratum.
Due to a printer's error, the word "nitrite" was altered to "nitrate" in two instances in the article, "Ever so cautiously, the FDA moves to-ward a ban on nitrites," (8 September, p. 887). The lead sentence should read," The hazard to animals and man of eating excessive amounts of nitrates and nitrites...." The first sentence in the fourth paragraph should read," These circumstances ... the existent but unquantified hazard of adding nitrites to food." Nitrites-not nitrates-are deliberately added to foods.
