Cyclosporiasis is a parasitic infection caused by the microscopic protozoan Cyclospora cayetanensis. This infection is usually spread through the fecal-oral route, where contaminated food or water is ingested. Recent outbreaks across the United States have highlighted the importance of proper food handling and hygiene practices to prevent the spread of this disease.
NPR’s Mary Louise Kelly spoke with Kali Kniel, a professor of microbial food safety at the University of Delaware, about the recent cyclosporiasis outbreaks. Kniel emphasized the need for individuals to take simple yet effective measures to prevent the infection.
Washing Hands and Produce
According to Kniel, the primary method of preventing cyclosporiasis is through good hand hygiene and proper food handling. Washing hands with soap and water for at least 20 seconds before and after handling food can significantly reduce the risk of infection. Additionally, washing produce under running water and scrubbing firm-skinned fruits and vegetables can help remove any potential contaminants.
Kniel noted that people often underestimate the importance of washing produce, thinking that it is not necessary for fruits and vegetables that are typically peeled before consumption. However, she emphasized that even when produce is peeled, the risk of contamination still exists. For instance, Cyclospora can survive on the surface of produce, even if it is peeled.
Outbreaks and Statistics
The recent cyclosporiasis outbreaks across the United States have been linked to various food sources, including salads, fruits, and vegetables. According to the Centers for Disease Control and Prevention (CDC), between May 1 and August 31, 2022, there were 629 reported cases of cyclosporiasis in 36 states. This represents a significant increase from previous years.
Kniel pointed out that the cyclosporiasis outbreaks are often linked to specific food sources, such as berries, leafy greens, and melons. She emphasized that individuals should be aware of the potential risks associated with these foods and take necessary precautions to prevent infection.
Prevention and Control
Preventing cyclosporiasis requires a multi-faceted approach that involves individuals, food handlers, and regulatory agencies. Kniel stressed the importance of proper food handling practices, including storing and preparing food safely, and preventing cross-contamination. She also emphasized the need for better food safety regulations and enforcement to prevent foodborne illnesses.
In addition to washing hands and produce, Kniel recommended that individuals take other preventive measures, such as avoiding consuming raw or undercooked foods, especially for high-risk groups like the elderly and young children. She also emphasized the importance of reporting any foodborne illnesses to local health authorities to facilitate prompt investigation and control measures.
Kniel concluded that preventing cyclosporiasis requires a collective effort from individuals, food handlers, and regulatory agencies. By taking simple yet effective measures, such as washing hands and produce, and practicing good food handling habits, individuals can significantly reduce the risk of infection and contribute to a safer food environment.
