美国境内大大小小的养猪场都知道这样一条规则:让健康的生猪从小定期服用抗生素,既能减少它们患病的几率,又能让生猪“吃得少,长得快”。不过,现在随着多种对各类抗生素有广泛抵抗力的“超级细菌”不断扩散,美国政府开始考虑,今后将禁止养猪场利用抗生素来“促进生猪上膘”的做法。 Large and small pig farms in the United States all know the rule that healthy pigs should take antibiotics regularly, reducing their chances of getting sick and allowing pigs to “eat less and grow faster.” However, with the continuous proliferation of various “super bacteria” that are widely resistant to various types of antibiotics, the U.S. government has started to consider prohibiting pig farms from using antibiotics to “promote the development of pigs” in the future.
