AB  - A sensitive and selective liquid chromatography-triple quadrupole-tandem mass 
      spectrometry (LC-ESI-MS-MS) method was developed for the routine analysis of 
      aflatoxins (AFB(1), AFB(2), AFG(1) and AFG(2)) and ochratoxin A (OTA) in tiger 
      nuts and tiger-nut beverage (horchata). A matrix solid phase dispersion was 
      adapted to eliminate lipidic interferences. The solid support was C(18), while 
      the elution solvent was acetonitrile. Mean recoveries obtained at two 
      fortification levels were 72-83% and 71-81% for horchata and tiger nut 
      respectively with relative standard deviations (RSDs) <13% and 15% respectively. 
      The LC-MS-MS method allowed quantification and identification at low levels in 
      two matrices. The method was applied for the routine analysis of tiger-nuts and 
      horchata samples collected from different supermarkets of Valencia (Spain) during 
      one year (March 2009-March 2010). A total of 238 samples were analysed and 32 
      samples were found positives for OTA, AFB(1), AFB(2) and AFG(2).
