U.S. officials declare an end to record-setting cyclospora outbreak, but its origin is still unknown

U.S. health officials announced on Friday the conclusion of the largest cyclospora food poisoning outbreak in the history of the United States. Despite the official end of the record-setting public health event, authorities stated that the specific origin of the outbreak remains unknown.

The announcement marks the resolution of a historically significant foodborne illness incident in the U.S., though the inability to trace its source leaves a notable gap in understanding how the widespread contamination occurred.
