Tonight, we continue our investigation into the use of antibiotics in healthy livestock. Public health officials say it’s high time무르익은 때 we pay attention because using them to promote growth and prevent disease in animals could have devastating consequences to our health in the future. That’s because a steady diet of these drugs can make bacteria morphed변하다 into strains that are antibiotic resistant. And these so-called superbugs could pose a serious threat to humans. American farmers give their animals more antibiotics than any other country in the world. But some farmers here and overseas are finding another way.
They call it the Danish Experiment, a source of pride for the country's 17,000 farmers. Unlike industrial farms in the US which use antibiotics to promote growth and prevent disease, Danish farmers use antibiotics sparingly드물게, only when animals are sick. The experiment to stop widespread use of antibiotics was launched 12 years ago when European studies showed a link between animals who were consuming antibiotic feed everyday and people developing antibiotic resistant infections from handling or eating that meat.
35-year-old Soren Helmer is a second generation pig farmer. When the ban started, he and his father thought the industry would suffer. In fact, since the ban, the Danish pork industry has grown by 43%, making it one of the top exporters of pork in the world. All of Europe followed suit in 2006. But the American Pork Industry doesn't want to. Without using growth promoting antibiotics, it costs only $5 more for every 100 pounds of pork brought to market in the US. That's a small price for public health, says Dr. Ellen Silbergeld, who’s been studying the antibiotic resistance link between livestock and people for the past decade.
According to one study, when different countries introduced certain antibiotics on farms, a surge occurred in people contracting antibiotic resistant intestinal장에서 기생하는 infections one to two years later. One, Campylobacter, increased 20% in Denmark and 70% in Spain. After the ban, a Danish study confirmed that removing antibiotics from farms drastically reduced antibiotic resistant bacteria in animals and food.
