美国食品和药物管理局表示，它在墨西哥一个农场发现了环孢子虫，该寄生虫被确定为大规模生菜传播疫情的源头。
The Food and Drug Administration says it found the cyclospora parasite at a Mexican farm identified as the source of a massive lettuce-borne outbreak.
华盛顿马修·佩罗恩--美国食品和药物管理局周五表示，其检查人员在墨西哥农场检测到环孢子虫，该农场被认为是美国历史上最大规模食源性寄生虫病爆发的罪魁祸首。
MATTHEW PERRONE WASHINGTON — The Food and Drug Administration said Friday that its inspectors detected cyclospora at the Mexican farm blamed for the largest foodborne illness outbreak of the parasite in U.S. history.
尽管有这一发现，但FDA表示尚不清楚这种寄生虫是如何进入泰勒农场工厂的生菜的。该机构表示，现已结束对此次疫情的调查，此次疫情导致美国各地出现近13，000例腹泻和其他疾病病例该声明是在该机构派遣调查人员前往墨西哥瓜纳华托的农场六个多星期后发布的。此次访问是该机构七年多来首次访问中国，此前在COVID-19大流行后，国际食品安全检查急剧减少。
Despite the finding, the FDA said it’s unclear how the parasite got into lettuce at Taylor Farms’ facility. The agency said it has now closed its investigation into the outbreak, which led to nearly 13,000 cases of diarrhea and other illnesses across the U.S. The announcement comes more than six weeks after the agency sent its investigators to the farm in Guanajuato, Mexico. The visit was the agency’s first time there in more than seven years following a steep drop in international food safety inspections after the COVID-19 pandemic.
FDA检查人员星期五说，他们在两个地方发现了环孢菌：一个废水池和一个用于生菜种植的排水沟。虽然目前还不清楚污染是如何发生的，但FDA表示，这些样本提供了“强有力的流行病学数据”，将疫情与泰勒农场联系起来。
FDA inspectors said Friday they found cyclospora in two places: a wastewater tank and a drainage ditch used for lettuce cultivation. While it’s unclear how the contamination took place, the FDA said the samples provide “strong epidemiological data” linking the outbreak to the Taylor Farms site.
美国据疾病预防控制中心称，官员上个月宣布疫情已经结束，环孢子虫是一种微型寄生虫，通常会导致水样腹泻，“伴有频繁甚至有时是爆炸性排便”。这种疾病称为环孢子虫病，比沙门氏菌和大肠杆菌等其他细菌引起的食源性疾病不常见。杆菌这种寄生虫通过人类粪便传播，目前尚不清楚污水如何污染了足够多的食物来感染这么多人。
U.S. officials last month declared the outbreak had ended Cyclospora is a microscopic parasite that commonly causes watery diarrhea “with frequent and sometimes explosive bowel movements,” according to the CDC. The illness, called cyclosporiasis, is less common than foodborne illnesses caused by other germs, including salmonella and E. coli. The parasite is spread through human feces, and it still isn’t clear how sewage could have contaminated enough food to sicken so many people.
墨西哥食品安全当局的监管机构8月份宣布，他们自己的调查没有在该设施的生菜或水中检测到环孢子虫。几天前，FDA被迫撤回了一项错误的检测结果，该结果错误地识别了在边境收集的泰勒农场生菜样本中的环孢子虫。
Regulators from Mexico’s food safety authority announced in August that their own investigation did not detect cyclospora in the lettuce or water at the facility. That conclusion came days after the FDA was forced to retract a faulty test result that had incorrectly identified cyclospora in a sample of lettuce from Taylor Farms collected at the border.
