This is Scientific American's 60-Second Science. I'm Steve Mirsky. Got a minute?
"We produce nine billion food animals in the United States every year. And most of these animals are fed antibiotics 2 throughout their life. And it's the single greatest use of antibiotics in the United States." Lance Price, director of the TGen North Center for Microbiomics and Human Health in Flagstaff, at the ScienceWriters2011 conference on October 16th.
"And then this is the thing that just drives public health people crazy: most antibiotics are fed to healthy animals to promote growth or to prevent diseases 3 that may be just occurring because of the way we're raising them. Racial overcrowding and unsanitary conditions—we call 'em production diseases. And so we're using these lifesaving drugs as production tools. It's pretty amazing.
"So most animals are raised in concentrated animal feeding operations, or CAFOs. I could not honestly engineer a better system for creating antibiotic 1-resistant bacteria than to introduce antibiotics to this setting 4. And that's exactly what we do every day in the United States. If we all recognize that antibiotic resistance 5 is one of the greatest threats to public health we face today, we have to do something about this."
Thanks for the minute. For Scientific American's 60-Second Science, I'm Steve Mirsky.
