The FoodNet surveillance system, which gathers foodborne disease data from ten states that account for about 15 percent of the US population, counted only 17 confirmed cases of cyclospora last year.
Operated by the Centers for Disease Control and Prevention (CDC) in Atlanta, FoodNet figures the cyclospora rate in the ten states at a mere 0.04 per 100,000. It means cyclospora comes dead last on the “top ten” list below.
(Number of cases and rate per 100,000 provided.)
- Salmonella, 7,444, 16.2
- Campylobacter, 5,825, 12.68
- Shigella, 3,029, 6.59
- Cryptosporidium, 1,036, 2.25
- Escherichia coli O157, 513, 1.12
- Shiga-toxin-producing E coli non-O157, 205, 0.45
- Yersinia, 164, 0.36
- Listeria, 135, 0.29
- Vibrio, 131, 0.29
- Cyclospora, 17, 0.04
According to newspaper archives, the last major cyclospora outbreak in the United States occurred five years ago in Florida when 300 people got the parasitic illness from contaminated fresh basil.
Isolated cases like the 17 that occurred in the ten FoodNet states last year are often associated with foreign travel to areas of the world where the parasite is more common.
