PHOENIX — Health officials say nearly two dozen more cases of a food poisoning outbreak linked to romaine lettuce grown in Arizona have been reported.

　　凤凰城卫生官员说，已经有近20多起由长叶莴苣引发的食物中毒事件被报道出来了，这种莴笋生长在亚利桑那州。

　　The Centers for Disease Control and Prevention said Wednesday that the total number of people sickened by a strain of E. coli is now 172 across 32 states.

　　美国疾病控制与预防中心周三表示，因大肠杆菌感染而患病的总人数已达172，横跨32个州。

　　At least 75 people have been hospitalized, including 20 with kidney failure. One death was in California.

　　至少有75人入院治疗，其中20人肾衰竭。一人死于加州。

　　Health officials say there is a lag time of two to three weeks between when someone falls ill and when it’s reported to the CDC.

　　卫生官员说，从有人生病到向疾病控制与预防中心报告，这期间有两到三周的滞后期。

　　The agency says the romaine was grown in Yuma, Arizona, and was last harvested April 16. So it should no longer be in stores and restaurants because of its three-week shelf life.

　　政府机构说，这种莴苣生长在亚利桑那州的尤马县，最后一次采摘是在4月16日。由于它的保存时间只有三周，所以它应该不会再出现在商店和餐馆里了。
