ARRUA, Andrea Alejandra et al. Presence of mycotoxins in commercially-prepared food for infants in the metropolitan area of Asunción, Paraguay. Pediatr. (Asunción) [online]. 2019, vol.46, n.2, pp.97-102. ISSN 1683-9803.


Mycotoxicoses are diseases caused by mycotoxins, secondary toxic metabolites produced by filamentous fungi. Infants are especially susceptible to this type of toxins due to the anatomical and functional immaturity of their digestive and immune systems, which is related to the amount of food eaten and their weight.


To determine the presence of mycotoxins in foods for infants sold in pharmacies and supermarkets in the Metropolitan Area.

Materials and methods:

66 units of products from six different brands of imported commercial sweet and salty preparations and strained foods from pharmacies and supermarkets in the Metropolitan Area were randomly collected. Subsequently, they were analyzed by the enzyme-linked immunoaffinity test (ELISA). The variance analysis and the subsequent comparison of means of mycotoxin concentrations were performed using the Tukey test (95% CI), with the InfoStat® statistic.


The prevalent mycotoxins were aflatoxins (AF) and T-2 Toxin, which were present in 39% of the sample units analyzed, both in preparations and in strains. In third order of importance we detected Ochratoxin A (OTA) in 18% of the units. Fourth, deoxinivalenol (DON) products were detected in 4%. There were significant differences between the preparations and the strains, with the strains having the highest concentration levels of all the mycotoxins studied.


Variable levels of AF, OTA, T-2 and DON were found in infant foods marketed in the Metropolitan Area. The strains showed a higher average concentrations of mycotoxins in all the products analyzed. Both AF and OTA exceeded the maximum limits allowed by international standards.
