Bacteriological features of dressed squabs at refrigeration temperatures

الملخص EN

The microbiological quality of 90 domestic squabs dressed collected from retail markets within Ismailia city was investigated.

A sample size was divided into 2 main groups (chilled group & frozen one) where the individual birds of each group were subjected to bacterial examination according the plane adopted.

The initial mean counts for total aerobes, psychrotrophs and staphylococci were 4.3 x 103, 5.9 x 103 and 6.8 x 102 cfu / cm2 of chilled bird respectively ; meanwhile Salmonella spp.

Could not be detected.

At the end of chill storage, the mean counts for total aerobes, psychrotrophs and staphylococci were 4.3 x 107, 4.7 x 106 and 3.1 x 102cfu / cm2 respectively.

As regard to the frozen samples, the mean counts for each of total aerobes, psychrotrophs and staphylococci were 5.3 x 103, 5.3 x 104 cfu / cm2 and non of staphylococci respectively, such count at the end of frozen storage .

Absence of the pathogenic bacteria was a characteristic of refrigeration advantage; meanwhile there was a significant increase in population of aerobic psychrotrophic microorganisms occurred on samples throughout the chilling storage period.
