Raw buffalo milk samples from the agroindustrial zone in upper Egypt were ana-lyzed for the presence of organochlorine and organophosphorus pesticides using gaschromatography–mass spectroscopy. Five organochlorine pesticides namely, alachlor, dield-rin, hexachlorobenzene, lindane and methoxychlor and three organophosphorus pesticideschlorpyrifos, malathion, and parathion-methyl were detected in the milk samples. In 44%of the samples, the concentrations of lindane and malathion residues exceeded tolerancelevels ... Read more

A total of 85 raw buffalo's milk samples were collected randomly from dairy shops (n=25), street vendors (n=30) as well as from farmer's houses (n=30) in Sohag Governorate. These samples were physically and chemically examined in order to determine whether they were adulterated by addition of water, partial skimming of fat, addition of inhibitory substances, preservatives or commercial additives and ...

Aim: This study evaluated the aflatoxin M1 (AFM1) in raw, pasteurized and ultra-heat treated (UHT) buffalo milk consumed in upper Egypt. Materials and Methods: Milk samples were collected from January to June 2013. The competitive enzyme-linked immunosorbent assay was applied. Results: All the tested samples were positive for AFM1, which were above the Egyptian regulations limits 0 ng/L. The raw ... Read more

egg yolk-polymyxin B (MYP) agar medium was used as selective medium for isolation of this group. All isolates were identified by several biochemical tests. Accordingly, psychrotolerant B. cereus group was found in 32% of the total ice cream samples. Also, psychrotolerant B. cereus group count in each sample was estimated. B. thuringiensis was isolated from the examined three kinds of ... Read more
