Microbial hazard or salted om El-Kholoul [Wedge shell-donax trunculus]

Sixty samples of salted Om El-Kholoul were collected from different localities in Giza, Alexandria and Ismailia. Collected samples were examined organoleptically and subjected to bacteriological examination for enumeration of aerobic, enterobacteriaceae, Staph. aureus, enterococci counts as well as isolation and identification of Vibrio parahaemolyticus. The mean counts/gm of Aerobes, Enterobacteriaceae, Staph. aureus, Strept. faecalis and Strept. faecum were 4.9 x 15[5], 4.8 x 10[4], 1.9x10[5], 1.5 x 10[5], and 8 x 10[2], respectively. V. Parahaemolyticus could be isolated from all examined samples. The weight, pH and sodium chloride percent of samples were estimated and the inhibitory effect of lemon juice [Citrus aurantifolia] on the microbial load of such samples was noticed

Sedimentation rate [a new equation] for airborne fungi in a libyan abattoir

A total of 80 air samples from different compartments of Slaughter House Shahaat [A Libyan abattoir] were examined mycologically. A number of 360 mould strains were recovered, at the top were dark moulds [87.22%], Aspergillus [6.67%], Penicillium [2.22%], Fusarium [1.94%]. Mucor and Absidia were also isolated. Sedimentation rate of cfu of moulds on 1 cm 2 was calculated

Incidence of some zoonotic agents and tuberculosis in slaughtered buffaloes [bubalus bubalis]

A total of 6000 buffalos [Bubalus bubalis] slaughtered for meat production at Cairo Abattoir were examined at post mortem during 1991-1992 for the presence of Cysticercus bovis, sarcosporidia, hydatid cysts, liver flukes and tuberculosis. The incidence rate was 0.32%, 0.88%, 0.60%, 8.44%, 4.96% for those affections respectively. Fascioliasis constituted nearly 80% of the parasitic affections. The lungs showed tuberculous nodules in 70.41% of the cases. Suggestive measures for control of such affections were mentioned

Mycoflora of imported frozen beef

A total of 95 cartons containing imported frozen beef cuts [21 forequarter, 29 flank and brisket, 37 hindquarter and 8 different cuts] were examined for the presence of mycoflora. A total of 125 moulds could be isolated and identified. The most frequent moulds were Aspergillus, 53 [42.4%], Dematiaceous moulds 30 [24%], Penicillium 22 [17.6%] and Trichoderma 5 [4%]. Significance of these moulds was discussed

Psychrotrophic spoilage mould in imported frozen beef cuts

A total of 95 cartons containing imported frozen beef cuts 21 forequarter, 29 fank and brisket, 37 hindquarter and 8 different cuts were examined for the presence of psychrotrophic moulds. A total number of 117 moulds could be isolated and identified. The most frequent psychrotrophic moulds were cladosporium 37 [31.62%], penicillium 23 [19.66%], aspergillus 17 [14.53%] and ulocladium 12 [10.27%]. Other psychrotrophs as alternaria, phialophers, rhizopus, fusarium, Trichoderma and Mucor. Significance of these psychrotrophic moulds was discussed
