Erratum
In the News and Comment article "Use of antibiotics in animal feed challenged" (12 Oct., p. 144) by Marjorie Sun, the rate of fatalities resulting from infections caused by drug-resistant Salmonella was incorrectly reported. The fatality rate resulting from these infections is 21 times higher than for disease caused by Salmonella strains that responded to conventional antibiotics. This finding was reported by Scott D. Holmberg et al. in Science, 24 Aug., p. 833.
