A Cyclospora outbreak that was witnessed in June is still under investigation. The police are still trying to find out the cause of the outbreak that made at least 275 people ill in the Midwest. The effectiveness and speed of the investigation has been criticized by one epidemiologist. CIDRAP’s director, Dr. Michael Osterholm said that the source of the outbreak should have been established a few weeks ago. He further added that he had fears that the state and federal investigators were slow because of the notion that the outbreak had ended. Virtually all illnesses were initially reported in late June and early July. This is an indication that fresh produce was the most likely source of the outbreak. If so, the produce in question has expired and is no longer available in the market.
According to Osterholm, the slowing down of investigations is not an indication that the outbreak wasn’t something the authorities should take lightly. There is potential for a second product harvested to cause more illnesses. This criticism has been countered by Dr. Patricia Quinlisk, an Iowa epidemiologist who noted that the officials were diligently working to identify the source of the outbreak. She said that the officials had narrowed the cause to numerous vegetables. They however, did not want to take the risk of establishing the wrong product as the cause. She further added that one of the key challenges of the investigation is that it revolved around Cyclospora, an organism known to have a long incubation period lasting for a number of days and even weeks. Another problem with this organism is that it thrives in fresh produce, and people who consume such foods consume a wide range, normally in salad form. It is therefore essential for federal and state officials to identify the accurate source of outbreak.
