Using antibiotics when they're not needed can make bacteria resistant and a human can potentially eat those bacteria especially if the meat is not cooked properly.

在不需要抗生素的情况下使用了抗生素，可能会使细菌产生抗药性，而人类可能会吃掉这些细菌，特别是如果肉类在没有得到有效的烹饪环境下。

This process can happen over and over again, and eventually, we could end up with strains of bacteria resistant to all current antibiotic treatments.

这个过程可能会一遍又一遍地发生，最终，我们可能会得到对目前所有抗生素治疗都具有耐药性的细菌菌株。

And every time bacteria reproduce, there’s a chance that the baby bacterium’s DNA will mutate -- and a chance that the mutation will make that bacterium resistant to an antibiotic.

每次细菌繁殖时，小细菌的 DNA 都有可能发生突变——而且这种突变有可能使细菌对抗生素产生抗药性。
