Biosafety against fungal contamination of hen's eggs and mycotoxins producing species

In the present work one hundred random hen's eggs were
collected from one of the poultry farm at El-Behera Governorate, Egypt
for diction of fungal contamination and mycotoxins production for
evaluation of the sanitary condition of the farm. The obtained results
proved that (38%) of the examined eggs were contaminated with moulds
species with a count of ranged from 11 to 17 x103/g and a mean value of
3.4 x103/g magma. The isolated moulds species could be identified into
Aspergillus (14%), penicillium (9%), Fusarium (1%), Mucor (6%), Rhizopus
(4%) and Claddosporium spp (5%). The genus Aspergillus, penicillium,
and Fusarium spp were further identified into Asp. Flavus, Asp.niger
& Asp. fumegatus; P.oxalicum & p.regulosum and Fusarium
graminarium. The isolated mould species were screened for mycotoxins
production under laboratory circumstances. The obtained results showed
that (10.25%) of the previous mould spp were able to produce mycotoxins
in synthetic media. Aflatoxins B1, B2, G1, G2 were produced by two
strains of Asp. flavus in total concentrations of 1.3 and 1.5 µg/g
mycelia, respectively. T2-toxin was produced by one strain of
penicillium regulosum with concentration 0.072 µg/g mycelia while;
Zearalenon toxin was also produced by one strain of Fusarium graminarium
in a concentration of 0.146 µg/g mycelia.The dangerous role of
contaminated hen's eggs at poultry farm by mould species as well as the
public health hazard and the high economic losses has been discussed.
Through light on the great attention for the prophylactic and control
measures that should be adopted in the poultry farm to overcome that
problems and achievement of the consumer safety.
