ABSTRACT
The study presents the results for 214 samples of grains and mixed meals produced in the short period of so called “wet harvest’96” and of 130 samples evaluated after 9-11 months of storage. The ochratoxin A (OA) content was determined on 109 samples using the ELISA method on RIDA-SCREEN R test set (NOACK). Almost a year long storage of cereals on farms of north-east Poland caused a multifold increase of fungi growth and OA content compared to the short period following the harvest. In this stage only 58% of cereal samples met the European Union (EU) standards for OA content (up to 5 μg/kg). Mixed meals for swine produced after almost a year long storage contained from 7.98 μg OA/kg at low mold contamination (below 9.9 x 103 colony farming units (CFU)/g) to 23.04 μg/kg (P
