Foodborne illnesses are an important environmental health concern, with cases often being associated with both food and water contamination. Cyclospora cayetanensis is a coccidian parasite that is transmitted through the environment and infects the human intestinal tract, commonly causing diarrheal illness. Cyclosporiasis is most prevalent in tropical and sub-tropical regions of the world, although cases occur all over the world annually. There is strong evidence of seasonality for cyclosporiasis cases with different regions experiencing peaks at different times of year. In the United States, cases have historically been associated with foreign travel and outbreaks associated with imported produce. Recently, domestic cases appear to be rising in the US, and there have been concerns raised that cyclosporiasis has become endemic. The spread of Cyclospora through the water supply is of particular environmental health concern to the FDA. To assess this concern, I reviewed cyclosporiasis case reports submitted to the CDC for evidence of trends associated with water. Only two jurisdictions in the United States included questions on water exposures on their case questionnaires, and those questions were not uniform and only included for a limited number of years. There was no evidence of water associated outbreaks or trends, and there does not appear to be a need for comprehensive water exposure questions on case questionnaires at this time.
