Chicken manure is one of the most wide spread waste worldwide. One of its hazardous properties is contamination with live pathogens or pathogens’ spores. Being introduced into soil for fertilization, fresh, cured or treated manure can cause soil contamination with those pathogens. Further, transmission of the pathogens through soil and plant tissues to human or animal food is possible. The objective of the present work was to reveal the level of pathogenic contamination of wheat grains cultivated on soil that was previously treated with cured chicken manure. Two types of manures M1 and M2 sampled from the large poultry farms situated in Russia were used to fertilize soil and obtain wheat grains (samples G1 and G2, respectively). Grains obtained with mineral fertilizers were used as a control (G0). Among 10 pathogenic bacterial species investigated, 6 were detected in both M1 and M2 samples - Listeria monocytogenes, Mycobacterium paratuberculosis,, Enterococus spp,, Campylobacter jejuni,, Bacillus anthracis,, Streptococcus dysgalactiae, the gene copy numbers for those bacteria revealed using RT-PCR was found to range between 2.22*104 and 1.19*108 gene copies per g manure. 5 of those species, except of C. jejuni, were also detected in both types of grains, while the gene copies number were found to be lower, thus they ranged between 1.45*103 and 8.81*103 copies per g grain. No bacterial pathogens were detected in G0 sample. Viral particles of bursal disease virus and avian orthoreovirus were not found either in manures nor in grains. It can be concluded that the risk of pathogenic transmission from the manures to grains exists, and that higher attention should be paid on their treatment to avoid the secondary infection of livestock and human.
