Interpretive Summary:

Technical Abstract: Incaparina is mainly a mixture of cottonseed and corn flours. It is given to 80 percent of Guatemalan children in their first year of age to combat protein deficiency. The aflatoxins and fumonisins producing fungi such as Aspergillus flavus and Fusarium moniliforme are commonly found in corn and cottonseed. It is possible that one or more of these toxins may be found in the Incaparina. Five samples of Incaparina collected from different importers were examined for fungal contamination and analyzed for the toxins. A. flavus was the predominant fungus in all the samples, whereas F. moniliforme was found in one of the samples. All samples contained aflatoxins ranging from 57-244 ng/g and total fumonisins (B1, B2, and B3) from 208-2107 ng/g. The identities of the aflatoxins were confirmed using a chemical derivatization method and LC/MS/MS analysis. The identities of the fumonisins were confirmed using LC/MS/MS analysis. Appropriate regulatory action was recommended for the import of Incaparina.
