美国正面临环孢子虫病疫情，确诊病例数可能超过11000例，其中超过300人住院治疗[1]。密歇根州疫情最为严重，报告超过7000例[1]。疾病预防控制中心正调查6起疫情，其中一起跨越9州的疫情与泰勒农场墨西哥公司销售的冰山生菜有关[1]。该公司已自愿召回27个州餐厅和15个州超市的生菜[1]。此外，Taco Bell与9个州的病例相关[1]。
专家指出此次疫情暴露了美国食品安全系统存在的深层问题。报告机制不统一，47个州要求向全国疾病报告监测系统（NNDSS）报告环孢子虫病，而其他州的报告仅为自愿性质[1]。诊断延迟也成为追踪的障碍，疾控中心假设从患病到收到报告有6周延迟[1]。公共卫生部门资金严重不足更是根本问题，特朗普政府2025年削减公共卫生经费11.4亿美元[1]，导致疾控中心人员减少25-30%，其中寄生虫病团队从11人缩减至3人[1]。食品安全倡导者Barbara Kowalcyk表示，"令我惊讶的是病例数量之大，以及它凸显的所有系统漏洞"[1]。
The United States is grappling with a significant cyclosporiasis outbreak, with confirmed cases potentially exceeding 11,000 and more than 300 people hospitalized [1]. The Centers for Disease Control and Prevention is investigating six separate outbreaks, one of which spans nine states and has been traced to iceberg lettuce sold by Taylor Farms de Mexico [1]. Michigan has been hit hardest, reporting over 7,000 cases [1].
Taylor Farms has voluntarily recalled lettuce from restaurants in 27 states and supermarkets in 15 states following the identification of the contaminated product [1]. The outbreak has also been linked to Taco Bell locations across nine states [1]. Public health experts warn that the true scope of the crisis may be obscured by systemic weaknesses. The CDC estimates a six-week delay between patient illness and report submission, and reporting requirements vary significantly across the country—47 states mandate cyclosporiasis reporting to the National Notifiable Diseases Surveillance System, while others report on a voluntary basis [1].
Structural vulnerabilities in the food safety and public health infrastructure have been exposed by the outbreak. The Trump administration's 2025 budget cuts eliminated $1.14 billion in public health funding, resulting in a 25 to 30 percent reduction in CDC personnel [1]. The agency's parasitic disease team has been particularly affected, shrinking from 11 staff members to just 3 [1]. Barbara Kowalcyk, a food safety advocate, stated: "What strikes me is the sheer number of cases, and all of the system vulnerabilities that it highlights" [1].
