A Cyclospora parasite outbreak spreading in the U.S. has prompted action from public health officials and a fast-food chain. The Centers for Disease Control and Prevention (CDC) has reported 1,645 cases across 31 states since May 1, with more than 5,100 suspected cases under investigation. So far, 145 people have been hospitalized.
As officials investigate the source of the outbreak, they shared that interviews with patients identified lettuce and salad greens as a common exposure among those who ate at Taco Bell restaurants. The Michigan Department of Health and Human Services (MDHHS), the CDC, and the Food and Drug Administration (FDA) are examining a possible link between the outbreak and fresh ingredients served at specific Taco Bell locations.
Taco Bell has voluntarily and temporarily removed a limited number of fresh ingredients from some restaurants as the investigation continues. In a statement, the company said, 'The health and safety of our guests is our top priority. Public health officials have not confirmed a link to Taco Bell or any specific ingredient, supplier, restaurant, or retailer.'
Cyclospora parasite and risks
According to the CDC, Cyclospora is a microscopic parasite that infects the small intestine after contaminated food or water is consumed. Dr. Tammy Lundstrom, Chief Medical Officer of Trinity Health, said, 'Cyclosporiasis is generally not a life-threatening illness for most people. The biggest concern is that it can lead to severe, prolonged diarrhea that can last weeks or even longer if not diagnosed and treated.'
Experts' food safety advice
Dr. Marc Siegel, senior medical analyst for Fox News, said the parasite has been detected particularly in packaged lettuce and salad bags, but no specific brand has been identified. Siegel said, 'In the meantime, the best strategy is to wash lettuce and all salad greens thoroughly and wash hands with soap and water before and after food preparation.'
Dietitian Caroline Margolis recommended avoiding pre-washed, bagged lettuce and salad mixes. Margolis advised, 'Instead, opt for whole heads of lettuce, discard the outer two to three leaves, and wash and rinse thoroughly.' Dr. Lundstrom also noted that iceberg lettuce is a better option for now, repeating similar washing steps.
CDC's safe food preparation guidelines
- Wash hands with soap and water before and after preparing raw fruits and vegetables.
- Wash all fruits and vegetables thoroughly under running water before eating, cutting, or cooking.
- Fruits and vegetables labeled 'pre-washed' do not need to be washed again at home.
- Scrub firm fruits and vegetables like melons and cucumbers with a clean produce brush.
- Cut away any damaged or bruised areas on fruits and vegetables before preparing and eating.
- Refrigerate cut, peeled, or cooked fruits and vegetables as soon as possible (within two hours).
Dr. Lundstrom concluded, 'It's important to remember that all types of fruits and vegetables are a fundamental part of our daily healthy diet. By following these practical preventive steps, people can continue to enjoy these nutritious foods.'
