Abstract An analytical method applying ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was validated for the determination of aflatoxins M2, M1, G2, G1, B2, B1, deoxynivalenol, ochratoxin A, fumonisins B1 and B2, hydrolyzed fumonisins B1 and B2, zearalenone and sterigmatocystin in crackers. The obtained recoveries (70 to 110%) and relative standard deviations (< 13%) were considered satisfactory. Method limits of quantification ranged from 0.20 µg kg-1 (sterigmatocystin) to 12.27 µg kg-1 (deoxynivalenol). The validated method was then applied for mycotoxin determination in 60 cracker samples (cream crackers and water and salt crackers) obtained from the metropolitan area of the state of Rio de Janeiro, RJ. Deoxynivalenol,...
