Michigander here. This shit can take weeks to show up and last for months if untreated! If you have the symptoms, get tested so you can go on antibiotics asap! I know people with it and it is brutal. As someone with a severe GI condition, im eating canned veggies and cooking everything, period. If you are disabled in a similar way, fresh and frozen produce is a no until they can figure out the source. It isnt life threatening until you get severely dehydrated from the shit-out-your-liquids-bug and the heat index is near the 100°F and you take medication which make the body less heat resistant(ssri's, adhd meds, anti psychotics, snri's, heart medications, diuretics, ace inhibitors, antihistamines, etc).
