The occurrence of enniatins (ENs) and beauvericin (BEA) in nuts, dried fruits and dates available in Valencia (Spain) was surveyed in this study. To do this, seventy-four samples of nuts, dried fruits and dates were analyzed for the determination of mycotoxin contamination. Mycotoxins were identified and quantified using an ultrasonic-C₁₈ extraction and LC-MS/MS with a triple quadrupole (QqQ) mass analyzer. The frequencies of contamination of nuts, shell, dried fruits and dates were 50 % , 80 % , 35.7 % and 83.3 % , respectively. Enniatin A (ENA) was the most predominant EN found in nuts (45.2 % ) while ENB was the most common EN found in dates (58.3 % ). The analytical results of the shell samples showed a protective effect of the shell, avoiding the contamination of the fruit with mycotoxins.
