美国近500人因吃麦当劳染病

As of Aug 16, the number of people infected with a parasite linked to McDonald's salads has grown to 476, the US Food and Drug Administration (FDA) said.

美国食品药物监督管理局（FDA）日前表示，截至本月16日，感染与麦当劳沙拉相关的寄生虫的人数已增至476人。

The lab-confirmed cases of Cyclospora infection were reported in 15 states, with 21 people now hospitalized. The people fallen sick range in age from 14 to 91, with two-thirds of them women.

美国15个州报告了经实验室确诊的环孢子虫感染病例，其中21人现已入院治疗。患病人群年龄从14岁到91岁不等，2/3为女性。

The FDA continues to investigate and is "currently reviewing distribution and supplier information for romaine and carrots," the agency said.

FDA表示将继续调查此事，目前正在审查长叶莴苣和胡萝卜的配送和供应商信息。

The probe has focused on Fresh Express salad mix containing those two ingredients.

含有上述两种原料的Fresh Express沙拉是调查的重点。

Health officials tested an unused package of the mix, which had been sent to McDonald's, and found Cyclospora in that sample.

卫生部门官员检测了一包送至麦当劳的未使用的Fresh Express沙拉，在样本中发现了可环孢子虫。

The fast food chain voluntarily stopped selling the lettuce blend at "impacted restaurants" -- about 3,000 locations -- on July 13 and has since turned to a new salad supplier, McDonald's said in a statement.

麦当劳在一份声明中表示，已于7月13日主动在受影响的约3000家餐厅停售这款莴苣沙拉，并已更换一家新的沙拉供应商。
