墨西哥卫生部周六表示，美国食品药品监督管理局针对与墨西哥Taylor Farms碎冰生菜相关的环孢子虫寄生虫疫情的调查，并未最终确定污染源。
Mexico's Health Ministry said on Saturday that a US Food and Drug Administration investigation into the cyclospora parasite outbreak linked to shredded iceberg lettuce from Taylor Farms in Mexico did not conclusively identify the source of contamination.
