If the uncooked meat is refrozen these new bacteria are put into suspended animation along with their living ancestors. This means that when the meat is rethawed there are not only the parents and their offspring, but the “grandkids,” “great-grandkids,” and so on, all reproducing faster than the proverbial rabbits. In other words, there are many more generations of bacteria to cause illness. By refreezing uncooked meat we increase the odds of becoming sick from eating it because we give harmful bacteria more chances to reproduce and thrive. So if you can’t cook it soon, throw it away, or give it to the dog, who is not as sensitive to those bacteria.

【生词注释】
ancestor n.祖宗，祖先

offspring n.子女，子孙

odds n. 可能的机会

【参考译文】
如果未煮熟的人再次被冷冻，这些新的细菌会有“祖先们”一起进入暂定生长状态。这意味着当肉再次解冻时，肉中不仅细菌的父母和子女，还有细菌的子孙和曾孙，这些细菌比兔子繁殖还要快。换句话说，有很多代细菌会导致病痛。将未煮的肉重新冷冻，我们吃肉的话就会增加患病的机会，因为我们会细菌更多繁殖和生存的机会。所以如果你马上将肉煮熟，就把肉扔了吧，或把它扔给对细菌不敏感的小狗吃。
