This July 4th weekend, get ready to give your raw berries and green salads a second thought. A parasite that can contaminate raw produce and cause severe, prolonged diarrhea is making headlines across several states. The culprit? Cyclospora, a single-cell parasite carried in human feces. It's a nasty bug that's been making people sick, with 145 cases reported by 17 states between May 1 and June 16, according to the US Centers for Disease Control and Prevention (CDC). At least 20 of those cases resulted in hospitalizations.
What's particularly concerning is the sudden spike in cases during the summer months. Michigan, for instance, typically sees around 50 cases of cyclosporiasis annually, but has now reported at least 170 cases in just 7 counties over the past nine days. New York State is also experiencing an unusual surge, with 107 cases reported outside of New York City since May 1, compared to its usual yearly average of 500-700 cases.
Despite the alarming numbers, federal and state health officials stress that there's currently no evidence of a single, multistate outbreak linking all cases. Investigations are ongoing to identify potential clusters and sources of illness.
So, how does this parasite end up in our food? Cyclospora is carried in human feces and gets into food when water contaminated with feces is sprayed on crops. Once on plants, it thrives in the humid environment of a farm field, multiplying and potentially causing illness. Dr. David Freeman, professor emeritus of infectious diseases at the University of Alabama at Birmingham, explains that two categories of produce seem to be the most common sources of outbreaks: 'basil and herb' plants like cilantro and basil, and fresh berries like strawberries, blueberries, and melons.
The good news is that cooking kills the parasite, so a simple solution is to heat your food. However, with the summer heat, people tend to opt for cooler options, leaving raw produce more vulnerable. That's why thorough washing is crucial. Freeman emphasizes that just washing with water is effective, but handwashing with soap and water, followed by an alcohol-based hand sanitizer, is even safer.
The symptoms of cyclosporiasis are unpleasant and can start anywhere from 2 to 14 days after consuming contaminated food. Patients experience frequent watery diarrhea, loss of appetite, and low-grade fever. Staying hydrated and replenishing electrolytes are essential, and seeking medical help is advised if symptoms worsen.
In my opinion, this outbreak highlights the importance of food safety, especially during the summer months when we're more likely to consume raw produce. It's a reminder to be vigilant and take simple precautions to protect ourselves and our loved ones from potentially harmful pathogens.
