生菜可以安全食用吗？新数据表明环孢子虫病病例正在放缓
在 7 月份感染高峰之后，这场爆发性腹泻疫情可能即将结束
来源:科学美国人This summer the U.S. has been gripped by a parasite-borne illness that causes explosive diarrhea and has basically taken iceberg lettuce off the menu.但美国疾病控制和预防中心的新数据以及各州数据表明，新感染病例可能正在逐渐减少。
截至 8 月 18 日，自 5 月份以来，CDC 已收到超过 15,000 例实验室确诊的环孢子虫病病例报告。 That’s an increase of more than 14,000 cases compared with May 1, 2025, through August 31, 2025. Some 828 people have been hospitalized, and two people died because of the infection, according to the CDC.
There are many more thousands of yet-to-be-confirmed cases, especially considering that some states are tracking the outbreak differently than the CDC does.例如，周四在密歇根州，当地官员表示，自 6 月以来该州已出现 14,277 例病例。 And the true number nationwide may be higher still because some people who get cyclosporiasis may not have serious symptoms, meaning they are less likely to go to the doctor or get tested for the bug.

这次疫情的爆发与卷心生菜有关，尤其是墨西哥泰勒农场生产的生菜。在被召回之前，这种生菜已在美国各地的商店和塔可钟餐厅出售。环孢子虫病是由寄生虫引起的，该寄生虫通过被感染的人类粪便污染的食物和水传播。 The Food and Drug Administration, which oversees food safety,has said it is “confident that all recalled iceberg lettuce related to this specific Cyclospora outbreak is off the market.”
