据外媒报道，美国麦当劳将逐步停止使用含人类抗生素鸡肉。麦当劳此举可改变饲养人员的生产方式，可对抗“超级细菌”问题。

麦当劳日前宣布，2年内美国麦当劳（McDonald's USA）的1万4000个店面将停止购买人类抗生素饲养出来的鸡肉。抗生素在人类医学上地位十分重要，人们在家禽上过度使用抗生素恐降低它对人体疾病的效果。

（Reuters） - McDonald's Corp's U.S. restaurants will gradually stop buying chicken raised with antibiotics vital to fighting human infections, the most aggressive step by a major food company to change chicken producers' practices in the fight against dangerous 'superbugs.'

The world's biggest restaurant chain announced on Wednesday that within two years, McDonald's USA will only buy chickens raised without antibiotics that are important to human medicine. The concern is that the overuse of antibiotics for poultry may diminish their effectiveness in fighting disease in humans. McDonald's policy will begin at the hatchery, where chicks are sometimes injected with antibiotics while still in the shell.
