Responsible Use of Antibiotics in Agriculture
RESPONSE TO KATIE COURIC'S RECENT CBS NEWS STORIES
Scientists have known for many years that bacteria can mutate to become resistant to antibiotics or pick up genetic material from other bacteria that have survived the antibiotic use, and then further spread this within the bacterial population. And this is exactly what has been happening on intensive farms across the U.S. over the last few decades.
Part of the problem with this overuse of low-dose antibiotics is the fact that while the low dose kills off the more susceptible bacteria first, it leaves behind those bacteria that aren’t susceptible – in other words, the ones that show resistance. And because the farmers generally use the same antibiotics over and over again, in the end the only bacteria left are those that are resistant. Without anything to control them, these resistant bacteria can multiply and easily spread from animal to animal, and then from farm to farm.
