The composition of mycoflora in storage rooms, and other rooms in a poultry-processing plant, as well as on the surfaces of egg shells was observed. The concentrations of both aflatoxin B₁ and ochratoxin A were determined in the shell eggs at room temperature and humidity, at a higher temperature and humidity, and in the eggs previously contaminated by Aspergillus flavus. We found that there was a reciprocal correlation between the presence of microscopic filamentous fungi in the air and on the working tables (Cladosporium spp. 45.5%, Penicillium spp. 36.4%, Mucor spp. 9.0%). The penetration of mycotoxins through the egg shell was relatively low and the residue limit of aflatoxin B₁ allowed (5 μg.kg⁻¹) was not exceeded in any sample of egg tested. However, the residue limit of ochratoxin A (20 μg.kg⁻¹) was exceeded in one case.
