%X Microbiological quality of raw milk from eight healthy donkeys reared in Campania Region was investigated. A total of 152 samples were analyzed in order to evaluate the milk safety status trough monitoring mesophilic total bacterial count (TBC) at 32ˇăC and 20ˇăC, psychrophilic TBC at 5ˇăC, Enterobacteriaceae, Salmonella spp., Listeria monocytogenes, Staphylococcus aureus and somatic cell count (SCC). The ranges for mesophilic bacteria at 32ˇăC, 20ˇăC and psychrophilic bacteria at 5ˇăC were, respectively, 2.80-4.00 Log CFU/mL, 2.84-3.92 Log CFU/mL and 1.27-2.12 Log CFU/mL. Enterobacteriaceae showed a load ranging between 0.68-1.93 Log CFU/mL. No pathogenic bacteria were isolated. Estimated SCC values were always under 50,000 cells/mL. Additionally quantitative changes of bacterial population in raw bulk milk during eight storing days at 8ˇăC and 3ˇăC, were evaluated. Firstly, fresh bulk milk was contaminated by bacteria with a mean TBC at 32ˇăC and 20ˇăC of 2.71 Log CFU/mL and 2.64 Log CFU/mL, respectively, whereas TBC at 5ˇăC and Enterobacteriaceae were not detected. After eight days of storage at 8ˇăC, TBC at 32ˇăC, 20ˇăC and Enterobacteriaceae increased by three Log and TBC at 5ˇăC by five Log. On the other side, after eight days of storage at 3ˇăC no gradual Log increase was detected. Our results showed that donkey milk could be a good healthy ingredient for feeding where good hygienic procedures are applied and storage is kept at temperature lower than 3ˇăC.
