The presence of AFM 1 in milk is a public health concern, since milk is a significant part of human diets across nations.   In economies where monitoring is low or non-existent, the possibility of contamination with AFM 1 might be increased. Our study aimed to detect and quantify the concentration of AFM 1 in fluid milk and milk drink of different brands, fat contents, packages and, heat treatments sold in the Metropolitan Area of Asunción. 80 samples were collected following a non-probability sampling method; acquired from supermarkets from the Metropolitan Area of Asunción. To quantify AFM 1 , the AgraQuant® ELISA Aflatoxin M 1 25 - 500 ppt was used. Non-parametric analysis was performed. All samples presented positive values for the detection limit (25 ng/kg); 85% of the samples showed values between 30 to 50 ng/kg, and 15% showed values over 500 ng/kg. There was no significant difference in the content of AFM 1 between fat contents, heat treatments, or types of packaging. However, brands differed significantly.
