随着与冰山生菜相关的环孢子虫疫情蔓延至九个州，美国人在社交媒体上将这一健康事件称为“生菜门”，且他们并不相信局势已得到控制。
美国卫生部长小罗伯特·F·肯尼迪此前试图平息人们对这种寄生虫病日益加剧的担忧，称已确定疫情源头，涉事企业已启动召回。然而就在几天之后，美国疾病控制与预防中心宣布新增数百名环孢子虫感染者——截至周五，全国总感染人数达到1947人。
据疾控中心数据，目前已有至少98人住院治疗，暂无死亡报告。
“有没有人和我一样，现在吓得不敢吃生菜了？”一名用户在TikTok发布的视频中这样问道。
卫生官员认为，受污染的冰山生菜产自墨西哥中部的泰勒农场工厂。
在周六发布的最新声明中，泰勒农场的一名发言人表示，截至周五，美国食品药品监督管理局尚未在其产品样本的环孢子虫检测中确认阳性结果。
“当近期环孢子虫疫情的源头受到质疑时，我们立即将所有可能受牵连的产品撤出市场，并且出于极度谨慎的态度，对该地区采购的所有冰山生菜启动了范围更广的召回，”该发言人说道。
泰勒农场还表示，已自愿暂停从墨西哥中部采购所有冰山生菜并暂停相关生产。该公司曾为塔可钟供应生菜，塔可钟方面称已将受影响产品从门店下架。
墨西哥政府周五也表示，其在泰勒农场的检测未发现该寄生虫的踪迹。该国联邦卫生风险防护委员会称，他们共检测了10份生菜样本和4份水样。
上周，美国食品药品监督管理局宣布一份来自泰勒农场的生菜样本环孢子虫检测结果为假阳性，这引发了更多困惑。但该局在周一表示，其调查和数据“仍在指向墨西哥中部泰勒农场生产的切碎冰山生菜”。
目前已确认出现感染病例的州包括伊利诺伊州、堪萨斯州、俄克拉荷马州、宾夕法尼亚州、印第安纳州、肯塔基州、密歇根州、俄亥俄州和西弗吉尼亚州。卫生官员怀疑全美41个州存在多起疫情，自5月1日以来，已有超过4100例实验室确诊病例和7400例疑似病例。
疾控中心表示，尽管已启动召回，但确诊病例数预计仍将上升，因为联邦和州政府官员可能需要长达六周的时间才能确认一名患者是否属于本次疫情关联病例。
环孢子虫是一种微观寄生虫，通常通过受污染的食物或水感染人类。它会引发一种名为环孢子虫病的胃肠道疾病，症状包括严重甚至“暴发性”腹泻。感染后潜伏期最长可达两周。
“我认为我们还不能说疫情已得到控制，”哈特福德医疗保健首席流行病学家尤利西斯·吴博士在接受哥伦比亚广播公司新闻采访时表示，“即便确实是这批生菜引发了疫情，也不意味着其他农产品不会成为感染源头。”
美国食品药品监督管理局周四报告了一起新的环孢子虫疫情，与未指明的产品有关。与此同时，北卡罗来纳州卫生官员表示，他们正在调查自5月1日以来该州超过560例可能与欧芹、香菜和生菜相关的病例。

Cyclospora outbreak dubbed “lettuce-gate” as concerns over parasitic illness spread across U.S.

As the cyclospora outbreak linked to iceberg lettuce spread to nine states, Americans have dubbed the health concern “lettuce-gate” on social media, and they aren’t convinced the situation is under control.
Days after Health Secretary Robert F. Kennedy Jr. tried to calm growing concerns about the parasitic illness, saying that the source of the outbreak has been identified and companies involved have implemented a recall, the Centers for Disease Control and Prevention announced hundreds more have been infected with cyclospora — bringing the nationwide total to 1,947 as of Friday.
At least 98 hospitalizations have been reported, but no deaths have been reported, according to the CDC.
“Is anyone else, like, deathly afraid to eat lettuce right now?” one person asked in a video posted on TikTok.
Health officials believe the affected iceberg lettuce came from a Taylor Farms facility located in central Mexico.
In a new statement on Saturday, a spokesperson for Taylor Farms said the U.S. Food and Drug Administration has not confirmed positive results from cyclospora testing of its product samples as of Friday.
“When questions were raised about the source of the recent Cyclospora outbreak, we immediately removed all potentially implicated product from the marketplace, and out of an abundance of caution we issued an even broader recall of all iceberg lettuce sourced from the region,” the spokesperson said.
Taylor Farms also said it voluntarily suspended all iceberg lettuce sourcing and production from central Mexico. The company supplied its lettuce to Taco Bell, which said it removed the affected products from its restaurants.
The Mexican government on Friday also said its tests found no evidence of the parasite at Taylor Farms. The country’s Federal Commission for the Protection against Sanitary Risks said it tested 10 lettuce samples as well as four water samples.
More confusion sparked last week when the FDA announced that a sample of lettuce from Taylor Farms that had tested positive for cyclospora was a false positive. But the FDA said Monday that its investigation and data “continue to converge on shredded iceberg lettuce from Taylor Farms locations in central Mexico.”
While illnesses have been confirmed in Illinois, Kansas, Oklahoma, Pennsylvania, Indiana, Kentucky, Michigan, Ohio and West Virginia, health officials suspect multiple outbreaks across 41 states, with more than 4,100 laboratory-confirmed cases and 7,400 suspected cases since May 1.
The number of confirmed cases is expected to rise despite the recall, due to the fact that it can take as long as six weeks for federal and state officials to determine if a sick person is part of an outbreak, the CDC said.
Cyclospora is a microscopic parasite that typically infects people through contaminated food or water. It causes a gastrointestinal illness called cyclosporiasis, which can result in symptoms like severe and sometimes “explosive” diarrhea. Symptoms can take up to two weeks to start.
“I don’t think we can say that this is under control yet,” Dr. Ulysses Wu, the chief epidemiologist for Hartford HealthCare, told CBS News. “Even if this lettuce was implicated, it doesn’t mean that other produce is not implicated as well.”
The FDA on Thursday reported a new cyclospora outbreak linked to unspecified products. It comes as health officials in North Carolina say they are investigating more than 560 cases there since May 1 that are possibly linked to parsley, cilantro and lettuce.
