Michigan is currently facing the highest number of cyclosporiasis cases, which is linked to a parasite often associated with severe gastrointestinal issues. Lettuce is a primary suspect, though officials don’t think a particular type of lettuce or any supplier is to blame.
In Michigan, cases have surged to 2,640, and the numbers have been climbing nationwide since last Friday. New York City is also seeing a notable rise, reporting 374 cases from May 1 to July 10, as the search for the outbreak’s source continues there.
With the understanding that cyclospora often comes from produce, and with suspicions cast on lettuce in this instance, it raises the question: should we hit pause on salads for our safety? At least for a while?
What foods should I avoid? Is washing enough?
The CDC has given broad advice on washing produce whenever possible, given that past outbreaks have implicated bagged salads, herbs, and certain berries.
Cooking is widely recognized as the most effective method to eliminate harmful organisms. If you’re consuming raw foods, thorough washing is the next best step, although it’s not foolproof.
This parasite can be particularly stubborn to remove from leafy greens because it may hide in nooks and crannies where water doesn’t reach effectively, warns Melissa Vaccaro, a senior food safety program specialist with the National Environmental Health Association.
Symptoms of cyclosporiasis include severe cramps, nausea, fatigue, and what people call explosive diarrhea. Interestingly, some infections show no symptoms, while others could land individuals in the hospital.
Dr. Manish N. Trivedi, a director of infectious diseases, suggests that if you don’t wash your vegetables at home, it might be wiser to avoid ordering them at restaurants or to opt for pre-cooked options, especially if your immune system is compromised.
“It’s all about weighing the potential risks and benefits. Everyone has a different situation,” Trivedi noted.
So…can I have a salad?
Historically, Cyclospora has been linked to imported foods, which are distributed nationwide; some may carry contamination while others do not, explained epidemiologist Jill Roberts from the University of South Florida.
Some suggest an extreme avoidance of raw foods, but Dr. Aaron E. Glatt argues this approach is too drastic. It’s essential that people don’t lose faith in consuming fresh fruits and vegetables, which are crucial for a healthy diet, Vaccaro emphasized.
The focus should be on identifying and removing contaminated products to prevent illness rather than discouraging the consumption of produce altogether. The guidance from Michigan is relevant for those in affected areas, but it doesn’t imply that everyone in the country needs to stop eating lettuce.
Properly washing herbs and berries and refrigerating them remains a good habit, regardless of current issues, advises Dr. Perry N. Halkitis. Just remember, “don’t panic.”
A glimmer of hope
Authorities are actively interviewing people about their food habits to track down specific stores, restaurants, and products involved. Research labs are stepping in to help identify the parasite.
However, an uptick in reported cases doesn’t automatically indicate more contamination, Vaccaro reassured. It also points to enhancements in clinical testing and public health monitoring, allowing for better detection and linking of cases that might have slipped under the radar in the past.
