联邦卫生官员周四表示，目前已有20个州确认出现与召回卷心生菜相关的寄生虫感染病例，这场美国同类疫情中规模最大的暴发范围进一步扩大。
美国食品药品监督管理局称，政府科研人员目前在佐治亚州、田纳西州和得克萨斯州三个州新增确认了环孢子虫病病例。此次疫情波及的其他州包括阿肯色州、艾奥瓦州、伊利诺伊州、印第安纳州、堪萨斯州、肯塔基州、马萨诸塞州、缅因州、密歇根州、密苏里州、内布拉斯加州、新罕布什尔州、北卡罗来纳州、俄亥俄州、俄克拉荷马州、宾夕法尼亚州和西弗吉尼亚州。
美国食品药品监督管理局表示，此次环孢子虫疫情的患病总人数现已达到11458人，高于上周报告的约10900人。此次疫情已导致两例死亡病例，均出现在密歇根州。密歇根州卫生与公众服务部表示，这两名死者均“存在严重基础疾病”。
美国食品药品监督管理局、美国疾病控制与预防中心以及各州卫生官员已将调查重点指向墨西哥中部一家由美国大型农产品供应商泰勒农场运营的农场。哥伦比亚广播公司新闻调查发现，在此次环孢子虫病疫情暴发前，美国食品药品监督管理局上一次对潜在疫情源头墨西哥泰勒农场进行检查还是在七年前。
美国食品药品监督管理局称，其工作人员正与墨西哥政府官员合作，持续对该农场的农产品进行检查和检测。该机构表示，“仍有信心与此次特定环孢子虫疫情相关的所有召回卷心生菜已全部下架”。
据美国疾病控制与预防中心介绍，环孢子虫是一种微观寄生虫，通常会引发“频繁甚至突发性水样腹泻”。此类疫情多发生在晚春和夏季。
这种喜好高温的寄生虫会感染肠道并通过粪便传播。这种被称为环孢子虫病的疾病，相较于沙门氏菌、大肠杆菌等其他病菌引发的食源性疾病更为少见。许多环孢子虫病病例始终无法追溯到特定食物或其他感染源。
本周早些时候，美国疾病控制与预防中心报告称，今年美国境内已确认约17180例环孢子虫感染病例。该机构称，其中已有922人住院治疗。此前美国环孢子虫感染最严重的年份是2019年，当时全国报告的感染病例约为4700例。

Cyclospora outbreak linked to recalled iceberg lettuce tied to 3 more states, FDA says

Parasitic illness cases linked to recalled iceberg lettuce have now been confirmed in 20 states, federal health officials said Thursday, expanding the scope of the largest outbreak of its kind in the U.S.
The Food and Drug Administration said government scientists have now identified cyclosporiasis cases in three additional states: Georgia, Tennessee and Texas. Other states impacted by the outbreak include Arkansas, Iowa, Illinois, Indiana, Kansas, Kentucky, Massachusetts, Maine, Michigan, Missouri, Nebraska, New Hampshire, North Carolina, Ohio, Oklahoma, Pennsylvania and West Virginia.
The tally of people sickened in the outbreak by the parasite cyclospora is now 11,458, the FDA said, up from about 10,900 reported last week. There have been two deaths linked to the outbreak, both reported in Michigan. The two residents had “significant underlying health conditions,” the state’s Department of Health and Human Services has said.
The FDA, U.S. Centers for Disease Control and Prevention and state health officials have focused their investigation on lettuce grown at a farm in central Mexico operated by Taylor Farms, a major U.S. produce supplier. CBS News discovered that prior to the cyclosporiasis outbreak, the FDA last inspected its potential source, Taylor Farms de Mexico, seven years ago
The FDA said its staffers are continuing to inspect and test produce at the farm, in cooperation with officials from the Mexican government. The U.S. agency said it “remains confident that all recalled iceberg lettuce related to this specific cyclospora outbreak is off the market.”
Cyclospora is a microscopic parasite that commonly causes watery diarrhea “with frequent and sometimes explosive bowel movements,” according to the CDC. Outbreaks tend to occur most often in the late spring and summer.
The heat-loving parasite infects the bowels and spreads through feces. The illness, called cyclosporiasis, is less common than foodborne illnesses caused by other germs, including salmonella and E. coli. Many cyclosporiasis cases are never linked to a specific food or other source.
Earlier this week, the CDC reported that there have been about 17,180 confirmed cyclosporiasis cases in the U.S. this year. There have been 922 hospitalizations, according to the agency. Previously, the worst year in the U.S. for infections was 2019, when about 4,700 illnesses were reported nationally.
