especially from the time between milking until it reaches to the consumers.
Pseudomonas species are considered as the most important psychrotrophs
that contaminate raw milk. Therefore, the incidence and identifications
of Pseudomonas spp. in raw cow`s milk and their surrounded environment,
secondly to evaluate the activity of the raw milk Lactoperoxidase System
(LPS) on controlling of Ps. spp. in raw milk at room temperatures
were studied. A total of 90 samples, 30 each of raw cow`s milk directly
post-milking (250 mL), potable water (100 mL) and cow`s manure (50 g)
were aseptically collected from different dairy farms at Sharkia province,
Egypt. In addition to, 100 swabs were collected from hands of milker,
dairy equipments and surface of udder and teats (25 each). The minimum,
maximum and mean values of total pseudomonas counts in raw milk samples
were 2.14, 6.21 and 3.54 log10 cfu mL-1, respectively.
There were a significant difference between control and activated samples
regarding the pseudomonas counts up to 8 h under room temperature storage.
From these results, it could be concluded that the activation of the LP-system
can be used to improving the keeping quality of raw milk during transportation
until suitable method of storage is applied by consumers or the factory.]]>Abd-El-Aal, S.F.,20042004Ahmed, A.K.,19951995Al-Ashmawy, A.M., M. El-Sherbini and M.S.
