Comparative study between the microbiological quality of commercial and homemade labenah

الملخص EN

A total of 50 commercial and homemade Labenah samples were collected randomly from supermarkets and houses (n=25 for each product) in Asiut Governorate.

It was concluded that the average of total counts of yeasts and molds and total coliforms were 8.8x102 and 9.6x102cfu /g in commercial labneh and 6x102 and 7.6x104cfu/g in homemade labenah, respectively.

Pathogenic E.coli could be isolated in percentage of 28% from homemade one.

The isolated pathogenic E.coli could be serologically identified to O103 : H2(EHEC), O26 : H11(EHEC), O125 : H21(ETEC), O26 : H11(EHEC), O55: H7(EPEC), O91(EPEC) and O125: H21(EHEC).

Serratialiquefaciens, Klebsiella pneumonia, Providenciarettgeri, Proteus mirabilis, Enterobacteraerogenes and Serratiamarcescens could be isolated and identified in percentages of 4%, 12%, 12%, 12%, 12% and 4% in the examined samples of homemade labenah.

Coliforms which could be detected in examined samples of commercial labenah were Citrobacterdiversus, Proteus mirabilis and Enterobacteraerogenes in percentages of 4%, 4% and 4%, respectively.

The results obtained show that labenah samples collected from Supermarkets were safer than that made at home.
