The United States faces its most critical year for cyclospora infections, a parasite that causes gastrointestinal disorders. With more than 30 states affected, cases already exceed the record of 2019. Health authorities maintain an open investigation to identify the origin of the outbreak, which so far has left no fatalities.
Research points to green leafy vegetables
Michigan has the largest number of infections: more than 3,300. After interviewing more than a thousand patients, health officials said that preliminary evidence points to lettuce and other salad greens as possible culprits. For this reason, they recommended buying whole lettuce, removing the outer leaves, washing them carefully and avoiding bagged presentations or ready-to-eat salad kits.
The Food and Drug Administration (FDA) reported that it continues to trace various agricultural products to determine the exact source of the outbreak.
Preventive measures and increasing numbers
The Taco Bell restaurant chain announced the temporary and voluntary withdrawal of some ingredients in selected establishments as a preventive measure. Federal authorities declined to confirm whether the investigation directly involves the company or its suppliers.
The Centers for Disease Control and Prevention (CDC) reported that since May they have identified more than 1,600 confirmed cases and another 5,100 remain under analysis. The figure is expected to continue growing in the coming weeks. Authorities are investigating a possible common outbreak in Michigan, Ohio, Kentucky and West Virginia, although they clarify that not all infections come from the same source.
Cyclospora is a microscopic parasite that infects the intestine and is transmitted through food or water contaminated with feces. The disease, called cyclosporiasis, usually causes severe diarrhea, cramps, nausea and fatigue, and is treated with antibiotics. Specialists consider that the increase in cases responds both to better detection methods and to environmental factors related to climate change.
