Occurrence of fungi and mycotoxins in corn silage, Jalisco State, Mexico

Abstract

The sedimentological, palaeontological and radiometric analyses of two cores collected in the Domingo Rubio tidal channel (Huelva estuary, SW Spain) permit us to recognize the main features of several tsunamigenic layers with different ages. Two tsunamigenic facies were differentiated with a foraminiferal record, largely dependent on the palaeogeography of the estuary. These bioclastic beds were deposited during a prehistorical tsunami (3.6-3.0 cal ka BP) and a historical tsunami (1531 CE), the latter is the first geological record of this high-energy event in Spain.

Ramirez-Alvarez, A.",,"2008",,"The aim of this study was to evaluate the chemical composition, mold count and mycotoxin contamination of corn silage collected during a six month-period. The results indicated that the chemical composition and the physicochemical parameters evaluated did not show significant variation during the sampling time. Fungal count on RBC ranged from 1.7 103 to 9 108 CFU/g. Mucor, Penicillium and Aspergillus spp. were the most frequent fungal species in the corn silage. Fusarium count ranged from 1.6 103 to 1.6 108 CFU/g in Nash Snyder culture media. Aflatoxin B, fumonisins, ochratoxin A, ochratoxin B, deoxynivalenol, and zearalenone were detected throughout the period of corn silage maintenance (100% positive samples). However, only deoxynivalenol levels were higher than the maximum limit recommended by the FDA. " 2008 Revista Iberoamericana de Micología.
