That sudden, violent stomach cramp isn't always the 24-hour bug you think it is. If you live in Virginia or Maryland and spent the last few days running to the bathroom, you might want to look closer at your salad bar habits.
Public health networks across the mid-Atlantic are currently tracking a sharp spike in cyclosporiasis. It's a parasitic intestinal infection that turns a simple summer lunch into a nightmare. In Maryland alone, state health officials confirmed 32 cases this year, with 28 hitting right after May 1. MedStar Health just flagged fresh cases at urgent care centers in Baltimore and Alexandria. Nationally, the Centers for Disease Control and Prevention is tracking over 145 cases across 17 states.
The numbers are climbing. The source is still a mystery. If you think a quick rinse under the kitchen tap makes your produce safe, you're entirely wrong.
The Sticky Truth About Your Produce
Cyclosporiasis comes from Cyclospora cayetanensis, a microscopic parasite. It doesn't care if your berries are organic or your lettuce came from a high-end grocery store.
Most people mistake this for typical bacterial food poisoning like Salmonella or E. coli. It isn't. Bacteria can multiply on your food if left out on the counter. Parasites don't do that. They just sit there, clinging tightly to the surface of your food, waiting for you to swallow them.
The big problem here is how sticky these parasite eggs actually are. Dr. Jonathan Thierman, president of Expresscare Urgent Care Centers, recently pointed out that fruits like raspberries are particularly hazardous. Why? Because they're full of tiny crevices.
When contaminated irrigation water or soil hits a crop, these microscopic eggs wedge themselves into the tight spaces of your food. Washing them under running tap water might get rid of visible dirt, but it frequently fails to dislodge the parasite.
Why Tracing This Outbreak Is an Absolute Mess
Health investigators at the FDA and CDC are hitting a wall trying to find the exact food source behind the DMV cases. It's easy to blame a single restaurant or a specific brand of bagged salad, but the biology of Cyclospora makes tracking it incredibly difficult.
First, consider the incubation period. When you get standard food poisoning, you usually get sick within hours of eating something bad. With this parasite, symptoms take about a week to show up. Sometimes it takes up to two weeks.
Think about everything you ate seven days ago. Can you remember every piece of cilantro, every slice of green onion, or every piece of garnish on your plate? Probably not. That delay makes patient interviews incredibly unreliable.
Second, the parasite undergoes complex molecular changes as it replicates. This means state labs can't easily link a case in Alexandria to a case in Baltimore, even if both people ate from the exact same shipment of herbs.
Historically, these summer outbreaks stem from:
- Fresh cilantro and basil
- Snow peas
- Green onions
- Pre-packaged salad mixes
- Imported berries
Right now, officials state there's no evidence of a single, multistate outbreak connecting every single patient. Instead, we're looking at multiple distinct clusters happening simultaneously because of widespread agricultural contamination.
What True Cyclospora Infection Feels Like
This isn't a mild stomach ache. The hallmark of cyclosporiasis is watery, frequent, and often explosive diarrhea.
People who contract it report having more than 10 episodes a day. The infection targets your small intestine, leading to massive fluid loss, extreme abdominal cramping, bloating, and severe nausea.
One of the most telling signs is prolonged, crushing fatigue. Because your body stops absorbing nutrients properly, you're left completely drained.
If you leave cyclosporiasis untreated, it doesn't just disappear. The illness can drag on for weeks, or even months, following a exhausting relapsing-remitting cycle. You think you're getting better, and then it hits you all over again.
While it rarely kills anyone, the long-term toll is miserable. Complications include severe malabsorption, gallbladder inflammation (cholecystitis), and reactive arthritis that can leave your joints aching for months.
How to Handle the Risk Right Now
You can't completely eliminate risk unless you cook every single thing you eat to 158 degrees Fahrenheit, which kills the parasite instantly. But nobody wants to cook their summer raspberries or boil their salad greens.
If you're eating raw produce in Maryland or Virginia right now, change your prep strategy immediately. Scrub firm fruits and vegetables with a dedicated brush. Don't just rely on water; use a produce wash or a vinegar solution, which can help loosen the sticky outer coating of the parasite eggs.
If you start experiencing persistent, watery diarrhea that lasts more than a few days, skip the over-the-counter anti-diarrheal meds. They won't fix this. You need a specific stool test from a doctor to look for Cyclospora oocysts.
If you test positive, standard food poisoning advice like "drink fluids and wait it out" is useless. You need a course of trimethoprim-sulfamethoxazole, commonly known as Bactrim. It's one of the only treatments that actually eliminates the parasite from your system. Get tested, get the right prescription, and stop waiting for a parasitic infection to clear up on its own.
