OK I keep seeing people refer to the Michigan parasite outbreak and then others will chime in “it’s in my state too!” so to clarify this for everyone it is a NATIONWIDE outbreak reported in 31 US states as of today, July 12th 2026. There is no reason to assume it is not present in the rest of them
NBC News’ tally shows at least 26 states have reported cases of the parasitic stomach illness, as health authorities race to find the source
The CDC is tracking cases but they are significantly lagging behind the states on numbers (their data is weeks behind) so it’s probably going to be most effective to check your individual state’s infectious disease tracking.
This is a parasite that usually causes about 3000 cases of illness per year in the USA, Michigan currently has reported about 2900 (the confusion about “Michigan outbreak” is because Michigan is the first that caught an uptick in cases and has been very proactive about trying to trace them). Last official update from Massachusetts was 18 cases here centered in Greater Boston. The CDC recommends NOT assuming there are no sources of the parasite in your state even if no cases have been reported.
It isn’t an unknown illness but it is an unusual quantity of cases, and the fact that they haven’t been able to pin down the source after weeks of tracking is what makes it particularly concerning this year (harder to contain).
Wash your hands, wash your produce, cook it ideally, and advocate for farm workers to have access to safe and hygienic toilet facilities
