Mycoflora study in a wheat flour mill of Argentina

Abstract

The mycoflora of the environment: wheat conditioning, milling and screening, and filling zone, as well as, raw material -wheat-, intermediate product -grits-and end product -flour-on day 1, and after cleaning improvements -days 45 and 90-were studied in an Argentine wheat mill. Samples were incubated at 28°C Deoxynivalenol was above the levels allowed in wheat, being acceptable in grits and flour. Aflatoxin and Zearalenone showed acceptable levels. When studied in vitro, 53% of Aspergillus flavus and 100% of Fusarium graminearum isolates, produced Total Aflatoxins, and Deoxynivalenol and Zearalenone, respectively.

Bioaerosols at plants processing materials of plant origin—a review

“…Until now, microbiological analyses of air showed that the concentrations of bacterial and fungal aerosols in plants processing plant materials usually range from 10 3 to 10 6 cfu m -3 (Jain 2000;Dutkiewicz et al 2000Dutkiewicz et al , 2001Góra et al 2004;Krysińska-Traczyk et al 2005;Skórska et al 2005;Tsapko et al 2015;Aringoli et al 2012). The activity like processing agricultural products (grain, hay, herbs) can be responsible for worker's exposure to viable microorganisms or their fragments and metabolites.…”
