ROJAS C., Liliana; WILCHES F., Ángela  e  DARGHAN C., Enrique. CO-OCURRENCE OF MICROORGANISMS AND TOXIC METABOLITES IN FOOD FOR CHILDREN. rev.udcaactual.divulg.cient. [online]. 2015, vol.18, n.1, pp.3-12. ISSN 0123-4226.

The importance of nutrition in infants makes it increasingly necessary to establish control measures to ensure safe food consumption. The microbiological quality of baby foods marketed in Pamplona (Colombia), reveals that 46.67% of the products studied violate the parameters of the Resolution of the Ministry of Health N° 11488 of 1984. 6.67% of the samples presented molds and yeasts exceeding the permissible values. This research assessed the co-occurrence of total coliforms, Escherichia coli, aerobic mesophilic bacteria, molds and yeasts; mycotoxins: aflatoxin, zearalenone and deoxynivalenol in baby food samples. For quaintification of mycotoxins standardized techniques were applied in the Toxicology Laboratory of the National University of Colombia. 30 samples with three types of co-occurrence in response to potential harmful effects of pollutants using a hierarchical cluster analysis were established. The co-occurrence rates associated to the source of pollution were biological 33.34% with only microorganisms, chemical only 3.33% mycotoxins and biological chemical 3.33%. No significant contamination according to Colombian law was observed in a 40%. The steadiness of this co-occurrence in other research can serve as a bio-indicator for the detection of various toxic agents, which often co-occur, allowing its control in products consumed by infants, employing preventive inhibitory growth methods of toxigenic fungi or food detoxification.
