The consumption of bracken fern (Pteridium aquilinum) as food is associated with a high incidence of cancer in humans and animals. We investigated the cytogenetic effects of bracken-fern extracts (hexane extract—HE, ethanol extract—EE, hot water extract—HWE and cold water extract—CWE) on chromosomes of peritoneal and bone-marrow cells of Swiss mice. In peritoneal cells, all four treatments (HE, EE, HWE and CWE) induced structural chromosome aberrations, but the EE also induced numerical chromosome aberrations. In bone-marrow cells both HE and CWE induced structural chromosome aberrations; additionally, the number of abnormal metaphases was higher in peritoneum than in bone marrow. We suggest that bracken fern induces cytogenetic damage through DNA strand breaks and affects chromosome segregation.
