美国食品药品监督管理局（FDA）已澄清，此前对泰勒农场（Taylor Farms）生菜样本的环孢子虫检测呈假阳性 [1]。尽管存在这一检测错误，FDA仍将该供应商位于墨西哥中部产地的碎冰生菜确定为引发多州疫情的主要源头 [1]。
本次环孢子虫疫情已导致美国至少1,645人感染，其中141人需要住院治疗 [1]。泰勒农场已召回8个品牌代码下的25种碎生菜和沙拉混合产品 [1]。
受疫情影响，多家连锁餐饮企业的经营出现明显下滑。塔可贝尔（Taco Bell）的客流量下降了18.9%，Chopt下降14.3%，而Chipotle和潘尼拉面包店（Panera Bread）的跌幅约为7% [1]。塔可贝尔已无限期从供应链中移除墨西哥产冰山生菜 [2]。
FDA正在继续追踪受污染产品的供应链并加强边境检测 [1]。
The U.S. Food and Drug Administration has acknowledged that a laboratory rapid test yielded a false positive for cyclospora in lettuce samples from Taylor Farms, yet continues to identify the supplier as the primary source of a multi-state outbreak [1]. The agency remains concentrated on tracing the supply chain and strengthening border detection efforts as the contamination investigation proceeds [1].
The 2026 cyclospora outbreak has infected at least 1,645 Americans, with 141 requiring hospitalization [1]. Despite the faulty test result, FDA investigators point to Taylor Farms' shredded iceberg lettuce produced at facilities in central Mexico as the likely culprit [1]. Taylor Farms has issued recalls covering 25 shredded lettuce and salad mix products across eight brand codes [1].
The outbreak has triggered significant business impacts across the restaurant industry. Taco Bell has experienced an 18.9 percent decline in customer traffic, while Chopt saw a 14.3 percent drop [1]. Chipotle and Panera Bread each reported approximately 7 percent decreases [1]. Taco Bell has removed Mexican-sourced iceberg lettuce from its supply chain indefinitely [2].
