Microbiological criteria of some meat products

A total of two hundred of meat product samples [Beef burger, Luncheon, Pasterma and Sausage] were collected randomly from different retail shops at Alexandria province and examined for their microbiological criteria. All the examined samples found to be contaminated with different types of microorganisms with the mean values of 8.20×10[2], 6.29×10[2], 5.40×10[2] and 8.28×10[2], respectively for total aerobic bacterial counts; total 5.57×10[2], 4.96×10[2], 5.83×10[2] and 7.64×10[2], respectively for Psychotrophic bacterial count; 5.27×10[2],4.65×10[2], 3.74×10[2] and 7.47×10[2], respectively for total Enterobactericeae count; 2.92×10[2], 3.50×10[2], 4.19×10[2] and 7.64×10[2], respectively for total Coliforms count and at last 4.7×10[2], 1.21×10[2], 1.22×10[2] and 1.00×10[2], respectively for total Yeast and Mold count. The incidence of identified Staphylococcus aureus was 68, 80, 60 and 88%, respectively and the incidence of identified Salmonella spp was 20, 26, 6 and 40%, respectively, while the incidence of identified Yersinia enterocolitica was 46, 40, 54 and 34, respectively

Enterobacteriaceae associated with farm fish and retailed ones

The present study was carried out for detection and identification of Enterobacteriaceae in retailed and farm fish as Tilapia nilotica and Mugil cephalus and in Kafr El Shiekh Governorate. The obtained results were revealed that 47 Enterobacteriaceae strains were isolated from 50 Tilapia niloticus fish samples with a percentage of 94% [25 from retailed fish and 22 from farm fish]. On the other side 46 isolates of Enterobacteriaceae strains were isolated from 50 Mugil cephalus with a percentage of 92% [22 from retailed fish and 24 from farm fish]. The most dominants isolated strains were Citrobacter spp., Enteriobacter spp., Klebsiella spp., Proteus spp., and Serratia spp. This together with the highly pathogenic Enterobacteriaceae including Salmonella spp. and E. coli
