绝大多数美国人至少会在一定程度上关注环孢子虫疫情的相关新闻，四成受访者表示他们如今会因此减少农产品的购买或食用。
女性比男性更有可能这么做，老年人比年轻人更甚。
此次疫情正牵动着美国人的注意力。关注环孢子虫寄生虫相关新闻的人数，几乎与关注伊朗冲突的人数不相上下。
对环孢子虫相关新闻极为关注的人群，如今更有可能减少农产品的购买或食用。
公众对FDA应对此次疫情的能力信心不一。总体而言，对FDA有信心的人数多于没有信心的人数，但几乎没有人对该机构表示“非常”有信心。
政治因素确实在一定程度上影响了公众对FDA的此番看法。共和党人中表示有信心的比例高于民主党人。
此次CBS新闻/舆观民调于2026年7月22日至24日期间进行，受访样本为具有全国代表性的2193名美国成年人。该样本根据性别、年龄、种族和教育程度进行加权，以匹配全美成年人的人口结构，权重依据美国人口普查局美国社区调查和当前人口调查以及2024年总统选举投票结果得出。本次民调的误差幅度为±2.7个百分点。

Cyclospora outbreak has many changing eating habits, CBS News poll finds; mixed and partisan confidence in FDA
July 26, 2026 / 9:00 AM EDT / CBS News
By Jennifer De Pinto
Most Americans are following news about the outbreak of cyclospora at least somewhat closely and four in 10 say they are now buying or eating less produce because of it.
Women are a bit more likely than men to be doing that, and older people more so than younger.
This outbreak is grabbing Americans’ attention. Nearly as many are following news about the cyclospora parasite as they are the conflict with Iran.
People paying very close attention to news about cyclospora are especially likely to be buying or eating less produce now.
Confidence in the FDA’s ability to deal with the outbreak is mixed. On balance, more are confident than not in the FDA, but few express “a lot” of confidence in the agency.
Politics does play some role in perceptions of the FDA on this. More Republicans express confidence than do Democrats.
