Ochratoxin A in dried vine fruit: method development and survey.

A method is described for the determination of OA in dried vine fruits (currants, raisins and sultanas) using acidic methanolic extraction, immunoaffinity chromatography cleanup and HPLC determination.  The limit of detection was estimated as 0.2 mg/kg and recoveries of 63-77% were achieved at 5 mg/kg.  OA and aflatoxins were determined in 60 samples of retail dried vine fruits purchased in the United Kingdom.  OA was found in excess of 0.2 mg/kg in 19/20 currant, 17/20 sultana and 17/20 raisin samples examined giving an overall incidence of 88%.  The maximum level of OA found was 53.6 mg/kg.  No aflatoxin was found in any sample analysed.
