The largest chicken meat producer in the United States says it will stop giving its birds antibiotics that doctors use to treat humans. Tyson Foods made the announcement on April 28 and said it would complete the change next year. Health experts say the overuse of the medicines is part of the reason more bacteria are becoming resistant to them. Farmers have fed livestock small amounts of antibiotics for many years. The drugs help the animals grow faster and prevent the spread of sickness among farm animals that live close together. But bacteria living in and on the animals develop and become immune to the drugs. These drug-resistant bacteria then enter the bodies of people who eat the birds or livestock. Then, infections in humans become more costly and difficult to treat. Sometimes, treatment does not work at all. While the use of antibiotics in birds and livestock is decreasing in the US and Europe, it is expected to increase in the developing world. There is a growing demand for meat there. Livestock producers in those countries are using methods that require antibiotics to keep animals healthy.
5. What do we learn about Tyson Foods from the news report?
6. What is the benefit of giving livestock antibiotics?
7. Why is the use of antibiotics expected to increase in the developing world?
