Among recent trends towards less processed foods is a growing consumer demand for raw (unpasteurised) dairy products. In spite of the public health risks and an increased awareness of pathogens in milk, proponents of raw milk consumption are of the view that pasteurisation kills beneficial microorganisms believed to have antimicrobial properties towards pathogens. This study thus aimed to exami...

During May 2013, the Pennsylvania Department of Health investigated an outbreak of campylobacteriosis among consumers of raw (unpasteurized) milk from a dairy certified by the Pennsylvania Department of Agriculture (PDA) to sell raw milk onsite, at retail stores, and at off-farm pick-up sites. Investigation by the Pennsylvania Department of Health and PDA identified six confirmed and two probab...

The characteristics of microbial populations in raw milk at the time of processing has a significant influence on shelf life, organoleptic quality, spoilage and yields of the raw milk, processed milk as well as on the other dairy products. Unfortunately, cold and extended storage of raw milk, as a common practice in dairy sector today, favour the growth of psychrotrophic bacteria. Therefore, th...

Studies were undertaken to compare the detection of anti-listeriolysin O antibodies (ALLO) and isolation of Listeria monocytogenes from meat and milk samples of sheep and goats. Out of 201 samples (87 of milk and 114 of meat) tested, 17.64% yielded Listeria species isolates. L. monocytogenes was isolated from 6.66 and 1.56% of meat (60) and (64) milk samples of goats, respectively, and 7.4% of ...

The incidence of human brucellosis is not documented in Rwanda despite several reports on the disease in cattle. Because brucellosis has been associated with abortion, the aim of this study was to investigate the prevalence of positive serology in women presenting with abortion and/or stillbirth. The study was done in Huye District, in the Southern Province of Rwanda, and the patients were recr...

AIM This review gives an outline of the assessment of enterotoxigenic Staphylococcus aureus tainting levels in raw milk from different sources in Egypt and characterization of enterotoxigenic strains utilizing a technique in light of PCR to identify genes coding for the production of staphylococcal enterotoxin (SE). The obtained data were compared with results from the application of the revers...

THE milk-fats from goats and sheep are used, although only to a small extent, as substitutes for those of cows and buffaloes in India. The component fatty acids and glycerides of these two fats have been studied by methods recently developed [Hilditch et al., 1929; 1930; 1931] in the case of cow butter-fats, in order to compare their composition with those of the latter and, in certain respects...

The aim of this study was to examine the expression patterns of SREBP-1 gene in milk somatic cells and its association with milk fat yield during early lactation in Sarda breed sheep. A sample of 20 Sarda ewes, aged between 4 and 5 years, in their third to fourth lactation were chosen. From each ewe 28 days after lambing milk yield was measured, and a 160 ml milk sample for the RNA extraction a...
