Recent Trends and Past Cyclosporiasis Outbreaks
Cyclosporiasis is a known parasitic disease that causes gastrointestinal symptoms and is often associated with contaminated produce, particularly imported fruits and vegetables. Past outbreaks have been linked to similar sources, prompting regulatory agencies to review safety protocols. The current surge, with over 2,000 cases reported, marks one of the larger outbreaks in recent years, although such outbreaks are not unprecedented.
Health officials have previously identified contaminated fresh produce as a common source, especially during warmer months when the parasite can thrive in water and soil. The current investigation aims to determine if a specific supplier or distribution chain is involved this time.
“We are actively working to identify the source of this outbreak and are advising the public to practice good hygiene and wash all produce thoroughly.”
— Dr. Jane Smith, CDC Epidemiologist
