Fresh Produce Safety: A Guide to Preventing Cyclosporiasis

Cyclosporiasis, a parasitic intestinal infection, has been affecting thousands of Americans across 31 states since May 1. The parasite, Cyclospora cayetanensis, causes symptoms like explosive diarrhea, loss of appetite, and stomach cramps. While health officials investigate the source, experts stress the importance of proper handwashing and produce handling to reduce the risk of infection.

Washing hands with soap and water for at least 20 seconds is crucial, especially after using the bathroom and before preparing food. Hand sanitizers are not effective against cyclosporiasis, so soap and water are the best options. When it comes to produce, a simple rinse under cool running water can help remove dirt and contaminants. However, no home washing method can completely eliminate the parasite from contaminated produce.

Different produce requires different washing techniques. For delicate items like berries, a gentle rinse is best, while firmer produce like potatoes and carrots can be scrubbed with a clean produce brush. Leafy greens like lettuce and spinach should be separated and rinsed thoroughly, with the outer leaves removed and discarded. Even if produce has a peel or rind, it's still a good idea to rinse it before cutting to prevent bacteria and dirt from being transferred to the edible portion.

Previous outbreaks have been linked to produce like raspberries, basil, and salad mixes. To reduce the risk of cyclosporiasis, experts recommend avoiding contaminated foods, cutting away bruised or damaged areas, and cleaning and sanitizing utensils and food-prep surfaces. Cyclosporiasis is commonly treated with a prescription antibiotic, and recognizing the symptoms is crucial to seeking medical attention. By taking these precautions and being aware of the risks, individuals can enjoy the nutritional benefits of fresh produce while minimizing the risk of foodborne illnesses.

The microscopic parasite that causes cyclosporiasis can adhere tightly to the surface of fruits and vegetables, making it difficult to remove. Despite this, experts emphasize that washing produce is still an effective way to reduce contaminants. A balanced diet that includes fruits and vegetables is essential, and sensible food safety practices can help balance the nutritional benefits with the risk of infection. By following these guidelines, individuals can take steps to protect themselves and their families from cyclosporiasis.
