DETECTION OF TOTAL AFLATOXINS AND OCHRA TOXINA RESIDUES IN SOME MEAT PRODUCTS

The food contamination with mycotoxins is a global problem. The most commonly observed mycotoxins are total aflatoxins (AFs) and ochratoxin A (OTA). Intense investigations have been conducted by studying the existence of the various mycotoxins to find out how they affect human food chain. This study was conducted on two hundred and fifty samples of
different meat products (minced meat, basterma, kofta, and luncheon and beef burger). Samples were randomly collected from different markets with divergent localities (Giza and Cairogovernorates) to screen their AFs and OTA contamination.The mycotoxin concentration was assayed using competitive direct enzyme- linked immunosorbent assay (CD-ELISA).
According to the location, the survey demonstrated that, the examined samples collected from Giza governorate showed higher aflatoxin residues percentage (83.2%) than in Cairo governorate (77.6%). On the contrary, the incidence of ochratoxin A, was higher in Cairo (84%) than in Giza governorate (77.6%)
