Mycotoxins are substances produced by several species of molds that can grow on food under certain conditions of humidity and temperature, and constitute a real risk to human and animal health. The objective of the present study was to determine the presence of Mycotoxins (Aflatoxins) in primary and processed foods for humans and farm animals in Riobamba, Ecuador. Twelve samples were taken with 4 replicates of primary foods: rice, chicken, raw milk, corn, alfalfa, and wheat; and, processed foods: chicken sausages, pasteurized milk, bread and concentrates for chickens, cows, and pigs from the different markets with the highest concentration of product offer, which were analyzed through the ELISA enzyme-linked immunosorbent method (Veratox® for Aflatoxin Quantitative Test and Veratox® Aflatoxin M1, NEOGEN) with the capacity to determine quantitatively aflatoxins B1, B2, G1, G2, M1. Of the total samples analyzed, 98 % presented contamination by aflatoxins, which according to the Ecuadorian Food Codex are within the allowed permitted parameters of less than 10 µg kg-1, for food and feed, and, less than 0.5 µg l-1 for milk.

Keywords : mycotoxins; aflatoxins; toxic; immunodepression; carcinogens.
