美国FDA澄清泰勒农场生菜环孢子虫检测结果为假阳性FDA Clarifies Taylor Farms Lettuce Sample Result Was False Positive
美国食品监督管理局(FDA)于2026年7月19日表示,经实验室专家重新检查,此前宣布呈环孢子虫阳性的泰勒农场(Taylor Farms)生菜样本结果应被视为“假阳性”。截至2026年7月19日,在此次多州环孢子虫疫情的产品检测中,尚无确认的阳性样本结果。尽管出现假阳性结果,泰勒农场此前对其源自墨西哥中部的冰山生菜进行的自愿召回决定保持不变,FDA也正继续与该公司合作,确保相关涉事产品退出市场。此次环孢子虫病疫情已导致美国约100人住院,无人死亡。根据官方调查,此次疫情与印第安纳州、肯塔基州、密歇根州、俄亥俄州和西弗吉尼亚州的百胜餐饮集团旗下塔可钟(Taco Bell)餐厅所供应的切丝冰山生菜有关。
The U.S. Food and Drug Administration (FDA) announced on July 19, 2026, that after laboratory experts re-checked results, a lettuce sample from Taylor Farms previously reported as positive for the cyclospora parasite is now considered a false positive. As of July 19, 2026, there are no confirmed positive sample results for product testing in connection with the multi-state cyclospora outbreak. Despite the false positive finding, Taylor Farms' earlier voluntary recall of its iceberg lettuce sourced from central Mexico remains unchanged, and the FDA continues to work with the firm to ensure implicated products are removed from the market. The cyclosporiasis outbreak, which has been linked to shredded iceberg lettuce served at Yum Brands' Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio, and West Virginia, has resulted in approximately 100 hospitalizations and no deaths.

01FDA澄清检测结果为假阳性FDA Clarifies False Positive Result
美国食品监督管理局(FDA)于2026年7月19日对泰勒农场(Taylor Farms de Mexico)的生菜样本检测结果进行了重新审查。此前在7月18日,官方曾宣布该供应商的一份切丝冰山生菜样本呈环孢子虫阳性。然而,经过实验室专家的重新检查,FDA在周日晚间发布声明,将这一结果修正为“假阳性”。
The U.S. Food and Drug Administration (FDA) re-reviewed the lettuce sample results from Taylor Farms de Mexico on July 19, 2026. This review came after officials had announced on July 18 that a sample of shredded iceberg lettuce supplied by the company had tested positive for the cyclospora parasite. Following a re-check by laboratory experts, the federal agency corrected the previous day's report, concluding that the finding should be considered a false positive.
FDA在声明中明确指出,截至2026年7月19日,在此次针对多州环孢子虫疫情的产品检测中,尚无任何确认的阳性样本结果。尽管前一日公布的阳性结果已被推翻,但相关的疫情调查工作仍在继续进行,监管机构正致力于厘清导致此次寄生虫感染爆发的具体源头。
In its statement released on Sunday evening, the FDA clarified that as of July 19, 2026, there are no confirmed positive sample results for product testing in connection with this multi-state cyclospora outbreak. While the previous positive finding has been walked back, federal officials and laboratory experts continue their investigation into the parasitic illness outbreak to identify the source of contamination.
02自愿召回与市场清理工作持续进行Voluntary Recall and Market Clearance Continue
尽管此次生菜样本检测结果被证实为假阳性,但泰勒农场(Taylor Farms)此前针对其源自墨西哥中部冰山生菜所做出的自愿召回决定并未发生改变。这家为百胜餐饮集团旗下塔可钟(Taco Bell)及多家食品零售商提供生菜的供应商,将继续维持其召回措施,以确保食品安全。
Despite the false positive laboratory result, Taylor Farms' earlier decision to initiate a voluntary recall of its iceberg lettuce sourced from central Mexico remains unchanged. The company, which produces lettuce for Yum Brands' Taco Bell restaurants as well as multiple grocery retailers, is maintaining its recall measures as a precautionary step.
美国食品监督管理局(FDA)在周日晚间的声明中表示,该机构已正式通知泰勒农场,并正继续与该公司密切合作,以确保与此次疫情相关的所有涉事产品均已成功从市场中清除。在此之前,泰勒农场曾向监管机构确认,被检测出假阳性的特定产品并不属于其当前召回范围的一部分。
The FDA stated in its Sunday evening update that it has notified Taylor Farms and continues to work closely with the firm to ensure that all products implicated in the multi-state outbreak are successfully removed from the market. According to the federal agency, Taylor Farms had previously confirmed that the specific product sample yielding the false positive was not part of its active recall.
03环孢子虫疫情的范围与健康影响Scope and Health Impact of the Cyclospora Outbreak
根据美国疾病控制与预防中心(CDC)的数据,此次环孢子虫病疫情已导致美国约100人住院治疗,目前并无人员死亡的报告。尽管该寄生虫病已在全美范围内导致数千人感染,但联邦和地方卫生官员正将重点放在这一特定的聚集性感染事件上。随着对污染源调查的推进,CDC等机构正在持续评估和监控此次疫情对公众健康的影响。
According to the Centers for Disease Control and Prevention (CDC), the cyclosporiasis outbreak has resulted in approximately 100 hospitalizations and no reported deaths. Although the parasitic illness has sickened thousands of people across the United States, federal and state health officials are focusing their efforts on this specific cluster of infections. The CDC and other agencies are continuing to monitor the health impact as the investigation into the contamination source proceeds.
调查表明,此次疫情与百胜餐饮集团(Yum Brands)旗下塔可钟(Taco Bell)餐厅供应的切丝冰山生菜密切相关。受波及的餐厅分布在印第安纳州、肯塔基州、密歇根州、俄亥俄州和西弗吉尼亚州等五个州。卫生官员正继续追踪向这些门店供应的受污染生菜的具体分销渠道,以防止更多消费者受到感染并确保食品安全。
The ongoing investigation has linked the outbreak to shredded iceberg lettuce served at Yum Brands' Taco Bell restaurants. The affected dining locations are spread across five states, which include Indiana, Kentucky, Michigan, Ohio, and West Virginia. Health authorities are continuing to trace the distribution channels of the contaminated lettuce supplied to these locations to prevent further infections and ensure public safety.
