Abstract. In the present work one hundred random hen's eggs were
collected from a poultry farm at El-Behera Governorate, Egypt for
detection of fungal contamination and mycotoxins production and
evaluation of the sanitary conditions of the farm. The obtained results
proved that (38%) of the examined eggs were contaminated with
moulds species with a count ranging from 11 to 17×10
3
cfu/g and a
mean value of 3.4 ×10
3
/g. The isolated moulds species were identified
into Aspergillus (14%), Penicillium (9%), Fusarium (1%), Mucor
(6%), Rhizopus (4%) and Cladosporium spp. (5%). The genera
Aspergillus, Penicillium, and Fusarium spp. were further identified
into Asp. flavus, Asp. niger and Asp. fumegatus, P. oxalicum and 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 species 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 produced by one strain of Fusarium graminarium in a
concentration of 0.146 µg/g mycelia. The dangerous role of
contaminated hen's eggs by mould species at poultry farm, as well as,
the public health hazard and the high economic losses have been
discussed. Great attention for the prophylactic and control measures
that should be adopted in the poultry farm to overcome these problems
and achieve the consumer safety has been recommended. |
