milk is considered a nutritious food because it contains several important nutrients including proteins and vitamins. conversely, it can be a vehicle for several pathogenic bacteria such as staphylococcus aureus. this study aimed to analyze the frequency of genes encoding the nine staphylococcal enterotoxins (ses) and enterotoxin gene profiles in s. aureus isolates derived from raw bovine milk....

background: milk is regarded as a unique source of food for all ages. when milk is exposed to various contaminants, including lead and cadmium, it is considered a risk to humans. the presence of some metal pollutants, especially cd and pb, facilitates their entry into the food chain and thus increases the possibility of their toxic effects on humans and animals. therefore, we decided to check l...

INTRODUCTION Listeria monocytogenes is of major significance in human and veterinary medicine. Most human Listeria infections are foodborne and the association of contaminated milk and dairy produce consumption with human listeriosis is noteworthy. In Ethiopia, there is limited data regarding the prevalence of L. monocytogenes in raw bovine milk and dairy products. The aim of this study was, th...

INTRODUCTION Milk is considered to be a healthy, nutritious food product. Microbiological quality is an important aspect in evaluating the quality of milk. METHODOLOGY A total of 603 bulk tank milk samples from 221 farms distributed across ten different regions were collected for milk quality assessment. Quality was judged by total viable count, and the prevalence of two foodborne pathogens (...

17 In pasture-based systems, changes in dairy herd habitat due to seasonality results in the 18 exposure of animals to different environmental niches. These niches contain distinct 19 microbial communities that may be transferred to raw milk, with potentially important food 20 quality and safety implications for milk producers. It is postulated that the extent to which 21 these microorganisms a...

BACKGROUND Fragility fractures associated with osteoporosis extract a large financial and personal toll on society. Pharmaceutical or dietary calcium intake is needed to increase bone mineral density to prevent fragility fractures. Although dairy products are a good source of calcium, patients who are unable to digest lactose tend to avoid them and are put at a greater risk for fracture than th...

the objective of this study was to determine the effect of co2 treatment on proteolysis, lipolysis and quality characteristics of refrigerated raw milk. four treatments of raw milk were selected (controlled milk (milk without any special treatment) and milks treated with co2 until ph = 6.4, 6.2, 6). all experiments were triplicate. samples were stored at 4°c for 10 days and were analyzed on 1, ...

Due to increasing attention from consumers on non-bovine milk types, and to the increase in the number of small dairy donkey farms in Italy, farmers require more advanced and reliable processing devices, in order to guarantee a safe product of high quality. To this aim, a new small-scale High-Temperature Short-Time (HTST) pasteurizer (72 °C for 15 s), prototyped by the authors, was tested on do...

Background: Milk is one of the most nutritious foods providing a variety of proteins, fats, minerals, and vitamins needed to maintain, grow, and develop the body. The aim of this study was to assess microbial and chemical adulterants of raw cow milk collected from dairy farms of Hlabisa villages, KwaZulu-Natal Province, South Africa. Methods: A total of 68 raw cow milk samples were obtained fr...
