Best Question:
Are all 8,000+ Cyclospora cases linked to shredded lettuce from Mexico?
It’s too early to say, but probably not. CDC has linked cases in Michigan, Ohio, Kentucky, Indiana, and West Virginia to shredded lettuce from Mexico. Just based on proximity, it seems like a good bet that Illinois cases, which are also growing quickly, might also be linked to Taylor Farms lettuce served at Taco Bells in the region.
At least some other outbreaks are probably unrelated. North Carolina, for example, has 300+ cases that the state says have not been linked to outbreaks in other states. And the FDA lists five separate Cyclospora outbreaks right now on its website, only one of which is linked to lettuce so far.
It’s possible that now that they’ve narrowed down a product, supplier, and growing region that we’ll start to see some of these other clusters linked - possibly to other restaurants and vendors besides Taco Bell that purchased Mexican iceberg lettuce via Taylor Farms. But if we had to guess, we’d say that some of this nationwide outbreak will be linked to lettuce and at least some of these cases will end up being other, smaller, unrelated clusters, travel-related cases, and just a general increase in one-offs detected due to the increase in testing. It may be days or even weeks until FDA and CDC are able to confirm, though. And for smaller outbreaks, don’t hold your breath – most Cyclo outbreaks are never solved because of how hard it can be to track down a source weeks after patients ate whatever made them sick.

There’s a lot of noise out there about how FoodNet no longer tracks Cyclospora. But in reality, it wouldn’t have helped catch or resolve this outbreak any sooner. It does limit CDC's ability to track longer-term disease trends and risk, though. And other cuts to federal and state programs are almost certainly affecting their ability to respond.
