Fungal contamination and selected mycotoxins in pre- and post-harvest maize in Honduras.

 

A total of 69 maize samples were collected from pre-harvest standing crops and on-farm storage facilities from 52 smallholder farms located within 4 regions of Honduras during Oct. 1992-Nov. 1993. Samples were visually assessed for insect damage and fungal spoilage, and the mycoflora were quantified on artificial media. The major components of the ear rot complex were Fusarium moniliforme [Gibberella fujikuroi], F. moniliforme var. subglutinans [Gibberella fujikuroi var. subglutinans], Penicillium spp., Stenocarpella maydis, S. macrospora and Acremonium spp. Representative samples were also assayed for mycotoxin content. Fumonisin B1 was detected in all 24 samples tested at levels of 68-6555 micro g/kg and aflatoxin was detected in 2 samples heavily contaminated with Aspergillus flavus. Moniliformin and tenuazonic acid were not detected in the samples tested.
