Coccidial Conamination of Raspberries: Mock Contamination with Eimeria acervulina as a Model for Decontamination Treatement Studies

摘要

Numerous outbreak have been reported since 1995 in the United States and Canada that were linked tot he consumption of imported fresh raspberries contaminted wit Cyclospora. Because Cyclospora has no laboratory animal hosts, Eimeria ac- ervulina, a common chicken coccidium similar in characteristics to Cyclospora, was used as a surrogate to test decontamination treatments. Raspberries were mock contaminated with E.acervulina-sporulated oocysts in a water suspension, then exposed to washing, freezing, heat, or irradiation before they were fed to chicks.
