A parasite that can cause prolonged diarrhea, known as cyclosporiasis, has been detected in 31 states in the United States, according to recent reporting. Authorities have not identified the source of the current outbreak, but prior outbreaks have been associated with specific foods. In earlier cases, cyclosporiasis has been linked to items including raspberries, basil, snow peas, green onions, and lettuce.
The reporting emphasizes that because the outbreak’s cause is still unknown, people should follow food-safety practices intended to reduce the risk of foodborne illness. Guidance focuses on how to prepare food safely and what types of foods and handling practices may increase exposure. With cases spread across many states, the information is aimed at helping consumers lower their risk while public health officials continue investigation into the outbreak’s origin.
The guidance reflects the pattern seen in past cyclosporiasis outbreaks, where contaminated produce has played a role, while acknowledging that the current outbreak’s specific contamination source has not yet been confirmed.
