Some 20,000 tons of antibiotics are used in the European Union and the US each year. More than half are given to farm-ani _ls to prevent disease and promote growth. _2_. Most researchers
3、 assumed that hu _ns bee infected with the resistant strains by eating contaminated meat.

4、ure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistan _, he said. The drugs contaminate the crops, which are then eaten. _4_ Mueller is particularly con _rned about a group of antibiotics called sulphonamides. _5_His _ys
5、is found that Swiss farm _nure contains a high per _ntage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This con _ntration is high enough to trigger the development of resistan _ among bacteria. But vets are not treating the issue seriously. There

But re _nt research has found a direct link between the increased use of these farmyard drugs and the appearan _ of antibiotic-resistant bugs that infect people. E. His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in ani _ls feed. F. They could also be leaching into tap water pumped from rocks beneath fertilized fields. E,D,B,F,A 模板,内容仅供参考
