Environmental Analysis

Menai Organics Ltd. has undertaken analysis of bracken, bracken compost and groundwater run-off in areas with bracken for the presence of the carcinogen ptaquiloside and related compounds.

Consumption of the bracken fern Pteridium aquilinum by cattle has been shown to induce bladder and intestinal carcinomas in cattle and to cause a number of diseases in other farm animals. An unstable glucoside named ptaquiloside, containing a reactive cyclopropane ring, has been isolated from the fern and its potent carcinogenicity proven.
