Citrinin in the diet of young and healthy persons living in balkan endemic nephropathy areas.

The dietary citrinin (CT) intake of 19 persons living in highrisk "Balkan Endemic Nephropathy" areas in Bulgaria was studied. Over 4 weeks, volunteers collected aliquots of their daily meals. Weekly samples were homogenized and analysed for CT by enzyme immunoassay (detection limit: 1ng/g). CT was found at least once in the weekly diet of 11 persons, maximum levels were at 6 ng/g. Considering the total amount of food consumed, the weekly CT intake of several persons exceeded 10 microgram. The data suggest that people living in high-risk nephropathy areas are exposed to dietary CT at considerable levels.
