Opis:
Objective: Contamination of feeds with pathogenic microflora and mycotoxins constitutes a serious threat both for animals and humans. The aim of the study was to determine the degree of risk of the occurrence of microscopic fungi, selected bacteria and mycotoxins from the trichothecene group in poultry feeds in western Poland. Results: In feed mixtures, the concentration of ergosterol (ERG), being a specific quantitative biomarker for the content of microscopic fungi, was determined. Grower and finisher feeds were characterized by a higher count of bacteria and fungi in comparison to starter feeds. A considerable variation was found in the amount of ergosterol in analyzed feeds. Mean ergosterol content in feeds amounted to 19.34 mg/kg. The most common genera of fungi detected in the tested feeds included Aspergillus, Rhizopus and Mucor. Irrespective of the type of feed, the proportion of trichothecenes group B was five times higher than that of trichothecenes group A in relation to the total content of these mycotoxins in samples. In terms of the analyzed mycotoxins, feeds contained the highest concentration of deoxynivalenol (DON). A statistically significant correlation was shown between DON and ERG and between total trichothecenes and ERG. Conclusion: Recorded results indicate that the level of microbiological contamination in feeds for broiler chickens produced in western Poland is within the requirements of the binding standards.

Opis:
Microscopic fungi are microorganisms commonly found in cereal products. Pathogens of cereals colonising kernels are responsible, among other things, for deterioration of the technological value of grain. However, the greatest threat is posed by mycotoxins produced by toxin-forming strains of these microorganisms. The aim of the present study was to determine the level of contamination with microscopic fungi and mycotoxins from the group of trichothecenes in wheat grain from Poland in a 4-year cycle. In the period 2006–2009, studies were conducted on the content of fungal metabolites (ergosterol [ERG] and type A and B trichothecenes) and the content of microscopic fungi expressed in colony-forming units (CFU) in wheat grain. A total of 129 grain samples were examined. Analysed wheat samples had similar contents of both the investigated fungal metabolites and levels of microscopic fungi. Contents of microscopic fungi were low. Concentration of ERG, on average, was 2.64 mg/kg, while in colony forming units this value ranged from 101 CFU/g to over 103 CFU/g. The total concentration of type A and B trichothecenes was also low and within the 4 years of the investigation did not exceed 0.062 mg/kg. Concentration of DON did not exceed 1,250 μg/kg, established as safe in grain for human consumption, in any of the tested samples. For the results collected in the years 2006–2009 and presented in this paper, correlations were calculated between the amount of mycoflora and analysed metabolites in 3 possible combinations: 0.7096 for ERG/total toxin concentration, 0.6086 for ERG/log CFU/g, and 0.4016 for the concentration of total toxins/log CFU/g. Highly significant correlations between the content of trichothecenes and the concentration of ERG indicate that the level of this metabolite is closely related to the content of mycotoxins in grain.
