This story deserves front-page status. Considering that antibiotics add to the cost of food, health care, groundwater cleanup, and the debt of poor nations, this is a potentially revolutionary development. The fact that the presence of antibiotic-resistant Enterococcus faecium has decreased with the reduction in antibiotics use in Denmark and that the incidence of diseases that the antibiotics might have prevented have risen very little has global implications. The added cost of 75 cents to bring each pig to production is overridden by the savings in the cost of antibiotics. In my view, cost has the lowest priority. The health benefits are enormous.
