Abstract

The aim of this work was to monitor flutriafol and pyraclostrobin residues in Brazilian green coffees. More than 10,000 samples were analyzed. The pesticides were extracted using the QuEChERS method and analyzed by LC-MS/MS. The validated method is fast, with 5 min runs, and efficient, as precision and accuracy showed RSD no greater than 5% and recoveries within the 88-119% range. LOQ for flutriafol and pyraclostrobin were 0.005 mg/kg. The results of the analyzed samples showed that the percentage of nonconformities regarding flutriafol increased throughout the years, with over 1200 samples (11.8%). On the other hand, just 15 samples (0.15%) presented residues above 10 μg/kg for pyraclostrobin. Considering that flutriafol is a toxic and carcinogenic pesticide, as well as the increase in the number of irregularities throughout the years, it becomes important to implement public actions to assure consumer safety.
