Studies on market hen eggs in Kafr El-Sheikh and El-Gharbia Governorates

A total of 135 egg samples were collected from Kafr El-Sheikh and El-Gharbia Governorates markets [80 and 55 samples, respectively] for determination of their quality. The obtained results showed higher mean T.C.C. and yeast count values in egg shell samples collected from Kafr El- Sheikh Governorate than those in EL-Gharbia Governorate, while, the mean mould count values were higher in EL-Gharbia Governorate. Moreover, the egg content samples collected from Kafr El-Sheikh Governorate showed lower mean T.C.C. and mould count values and higher mean yeast count values than those in EL-Gharbia Governorate. Serological typing of the 8 salmonella isolates, 4 from each Governorate, revealed the presence of two serotypes; with an incidence percentage ranging from 25% to 75%. Residues of inhibitory substance were detected in 5% and 9.1% of the examined egg samples collected from Kafr EL-Sheikh and EL-Gharbia Governorates, respectively. Total aflatoxin content residues were detected in 16 samples [9 and 7 from Kafr EL-Sheikh and EL-Gharbia Governorates, respectively]

Studies of the mycological quality of infant milk foods

160 r and om samples of dried infant milk foods representing four br and s [40 samples br and A locally made based infant formula, 40 samples br and B imported milk based infant formula, 80 samples br and C and D imported infant milk powder] were collected from different pharmacies in Cairo and Giza to be mycologically examined. Yeasts and moulds were detected in 35, 20, 15, and 27.5% of examined samples of br and s A, B, C, and D with mean counts of 41.42, 30, 35, and 21.81/g, respectively. Yeasts were isolated from 5%, 2.5%, and 5% of examined milk br and s A, B, C, and D, respectively, while moulds were detected in 35%, 20%, 15%, and 22.5% with a mean value of 39.28, 23.75, 30, and 42.44/g of examined br and s, respectively. Yeasts and moulds belonging to the genera C and ida, Saccharomyces, Rhodotorula, Cladosporium, Aspergillus, Alternaria, Mucor, Penicillium, Rhizopus, Absidia, and Scopulariopsis were isolated from the examined milk br and s. The significance of isolated fungi as well as suggestive control measures for production and h and ling of the infant milk foods were discussed
