Ochratoxin A in grape juice and wine.
37 different grape juices and 21 red wines were analyzed for their contents of ochratoxin A at the State's Veterinary and Food Research Institute of Saxony-Anhalt in Halle in 1999 and the 1(st) quarter of 2000. Ochratoxin A was found in 78 % of the grape juices and 100 % of the wines. 27 % or 33 % respectively exceeded the EC Commission's lately intended proposal for an ochratoxin A maximum permissible level which is 0.5 ppb. A higher contamination rate for wines originating from southern growing regions of the EC was noticeable.
