Will the U.S. hog industry ever kick its reliance on low-dose antibiotics?
The editors of Scientific American recently encouraged U.S. hog farmers to “follow Denmark and stop giving farm animals low-dose antibiotics.” Sixteen years ago, in order to reduce the threat of increased development of antibiotic resistant bacteria in their food system and the environment, Denmark phased in an antibiotic growth promotant ban in food animal production. Guess what? According to Denmark’s Ministry of Food, Agriculture and Fisheries the ban is working and the industry has continued to thrive. The government agency found that Danish livestock and poultry farmers used 37 percent less antibiotics in 2009 than in 1994, leading to overall reductions of antimicrobial resistance countrywide.
