A parasite commonly linked to contaminated fresh produce has caused an outbreak of cyclospora infections, affecting over 1,500 people in Michigan and prompting investigations in 30 other states. The exact source of the outbreak is still unknown, but there are ways to protect yourself and still enjoy summer’s bounty of fruits and vegetables.
Understanding Cyclospora
Cyclospora is a microscopic, spherical parasite that commonly causes watery diarrhea “with frequent and sometimes explosive bowel movements,” according to the U.S. Centers for Disease Control and Prevention. The heat-loving parasite infects the bowels and spreads through feces.
Previous outbreaks have been linked to raspberries, basil, cilantro, snow peas, and salad mixes. Cyclospora surges can be tricky to investigate, and food poisoning sources can be hard to establish. Investigations can take months and sometimes never find a clear source.
Food Safety Tips
While the source of the outbreak is unknown, it’s a reminder to always practice basic hygiene, including washing hands with soap and water after using the bathroom and before handling food. Dr. Erika Noel, an assistant professor at Hawaii’s medical school and a pediatrician, recommends washing produce thoroughly, especially items like cilantro and basil, and cooking produce to an internal temperature of 158 degrees Fahrenheit or higher to kill cyclospora.
Research shows that washing fruits and vegetables in vinegar can be helpful. Vinegar won’t kill the parasite but can help remove it. Noel recommends submerging produce in a bowl filled with three parts water and one part vinegar and swishing it around for a few minutes.
Some produce can be challenging to clean, like broccoli and cauliflower, and berries. Anything grown underground and covered in thick dirt, such as root vegetables like carrots, potatoes, and radishes, can also be tough to clean.
Stay Safe, Enjoy Summer Produce
Noel doesn’t want the outbreak to lead to people avoiding eating fruits and vegetables; the health benefits outweigh the risks. “We don’t need to panic,” she said. Just be aware and ensure basic hygiene habits, which is always a good practice.
