Abstract
The presence and/or accumulation of mycotoxins in foods intended for human and animal nutrition is a constant concern for the harmful health effects resulting from ingestion. The aims of this communication were to analyze samples of feed and raw materials for manufacturing and to determine the presence of strains of filamentous fungi with toxigenic capacity. The values of frequency in the total samples (N = 422), indicated 63% of contamination, where A. flavus represented the most common (29.8%), while in feed and raw materials separately, indicated A. flavus has the highest value in both categories. In the analysis of different type of raw materials, A. flavus contaminated all types of samples, with the bran and soybean meal substrates having higher values for this Aspergillus, and corn substrate more fungal contamination. These results would demonstrate that the presence of mycobiota with toxigenic potential in food for animal feed is a disturbing reality.
Highlights
For the reason that many food intended for animal nutrition are an important channel introducing hazards on the human food chain, it is safety should be evaluated and valued before being fed to the animals
Many species of filamentous fungi are able to produce mycotoxins, but those belonging to the genera Aspergillus, Fusarium and Penicillium are especially important in notorious analysis of the contamination of food for human and animal consumption, as there can be consequent adverse effects to health if they are ingested (Bryden, 2011), estimating that at least 300 of these metabolites are potentially toxic to animals and humans (Huwig et al, 2001)
Relative density of filamentous fungi whit toxigenic potential in total samples The results indicated that A. flavus has the highest value of relative density in both feed and raw material, followed by Fusarium spp. and A. niger (Table 2)
Summary
For the reason that many food intended for animal nutrition are an important channel introducing hazards on the human food chain, it is safety should be evaluated and valued before being fed to the animals. While mycotoxin production from fungi depends on environmental conditions and food storage, determining the degree of contamination of feed and raw materials, potentially indicates the presence of these metabolites in these substrates allowing us to monitor and control measures throughout the production chain. For this reason the objective of our study was to assess the degree of contamination in feed and raw materials used for manufacturing by identifying mycelial fungi with mycotoxigenic potential
