Abstract

Fifteen fresh soft cheese samples (Kareish and Damietta) were
collected from shopkeepers, retail stores and rural markets. A
survey was conducted to determine the incidence of mycotoxins in soft cheese and the experiments were conducted to determine qualitatively and quantitatively detection of aflatoxin
Ml,quantitative detection of ochratoxin A and isolation and identification of mould contaminant.
Of the 50 fresh soft cheese samples tested 8 (32%) and 12 (48%) were found out to contain aflatoxin M 1 for (Kareish and Damietta) respectively, while through usage of lateral flow test ( strip field test).
For further confirmation of results by usage of immunoaffinity columns with flurometric assay revealed presence of aflatoxin Ml in mean concentration of 3.6 ± 0.6 (ppb) for kareish cheese samples and 6.7 ± 1.35 (ppb) for Damietta cheese samples.
Out of 12 randomly chosen kareish cheese samples undergone
detection by immunoaffinity columns with flummetric assay for
ochratoxin A presence revealed mean concentration of 0.63 ± 0.48
(ppb) also, 12 randomly chosen Damietta cheese samples revealedmean concentration of2.1 ± 0.35 (ppb).
Forty four percent (44%) of kareish cheese tested samples were contaminated with mould the high level of contamination was 1.5 <I 03; the low level was 10 and the mean value was 2.54x 102 ± 6.61 x 10 c f u / gram.
