Dung to Death
Fields across Europe are contaminated with dangerous levels of the antibiotics(抗生素)given to farm animals.The drugs,which are in manure sprayed onto fields as fertilizers(肥料),could be getting into our food and water,helping to create a new generation of antibiotic-resistant“superougs”。
The warning comes from a researcher in Switzerland who looked at levels of the drugs infarm slurry.__(1)___
Some 20,000 tons of antibiotics are used in the European Union(欧盟)and the US each year.More than half are given to farm-animals to prevent disease and promote growth._(2)_
Most researchers assumed that humans become infected with the resistant strains by eatingcontaminated meat?But far more of the drugs end up in manure than in meat products,saysStephen Mueller of the Swiss Federal Institute for Environmental Science and Technology inDubendoff.__(3)_
With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year,this pathway seems an equally likely route for spreading resistance,he said.Thedrugs contaminate(污染)the crops,which are then eaten.___(4)___-
Mueller is particularly concerned about a group of antibiotics called sulphonamides.(磺胺)___(5)___ His analysis found that Swiss farm manure contains a high percentage of sulphonamides;each hectare(英亩)of field could be contaminated with up to 1 kilogram of the drugs.This concentration is high enough to trigger(启动,促使)the development of resistance among bacteria(细菌)?But vets are not treating the issue seriously.
There is growing concern(越来越多的关注)at the extent to which drugs,including antibiotics,are polluting the environment.Many drugs given to humans are also excreted(排泄)unchanged and are not broken down by conventional sewage treatment.
练习:
A They do not easily degrade or dissolve in water,
B And manure contains especially high levels of bugs that are resistant to antibiotics,he say,
C Animal antibiotics is still an area to which insufficient attention has been paid.
D But recent research has found a direct link between the increased use of these farmdrugs and the appearance of antibiotic-resistant bugs that infect people.
E His findings are particularly shocking because Switzerland is one of the few countrieshave banned antibiotics as growth promoters in animal feed.
F They could also be leaching into tap water pumped from rocks beneath fertilized fields.
