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...

Different technologically treated Italian milks (whole and semi-skimmed ultra-high temperature (UHT), pasteurized and microfiltered milk), collected from 2009 to 2012, were evaluated for nutritional and technological properties. No significant differences in calcium and sodium were detected (p > 0.05), while significant differences were observed concerning phosphorus content, between whole and ...

The shelf life of pasteurized milk is limited by heat-stable proteases that undergo depolymerization, causing age gelation and bitterness. Proteolysis of milk during storage can be attributed to both native proteases and the proteases produced by bacteria, such as plasmin, which is the major native protease in milk. Ultra-high temperature (UHT) processing (>135°C for 2 s) inactivates proteases ...

background: antibiotics are an important class of drugs which are commonly used in veterinary for therapeutic, prophylactic and growth promotion purposes. antibiotic consumption may leave some residues in livestock food products leading to human health problems as well as failure in fermentation processing. the objective of this study was to investigate the antibiotic consumption pattern in ani...

food borne viral infections are recognized increasingly as human illneses. hepatitis a virus (hav) is an important pathogen which has been responsible for water and many food – borne outbreeks especially milk . in this study for approaching to best diagnosis method of hav in milk by elisa technique, various dilutions of hav antigen (1 ml/l, 10-3 ml/l, 10-6 ml/l, 10-9 ml/l) were added to uht mil...

Mastitis is known as the most common disease syndrome in the dairy industry. Treating mastitic lactating animals with antibiotics is a veterinary practice to cure the disease. However, the antibiotic used may persist in the milk for a period of time depending on drug selected, dosage applied, route administered, body weight of the animal treated, etc. Antibiotic residues in milk are of great co...

Milk is a key component in infant nutrition worldwide and, in the Western parts of the world, also in adult nutrition. Milk of bovine origin is both consumed fresh and processed into a variety of dairy products including cheese, fermented milk products, and infant formula. The nutritional quality and processing capabilities of bovine milk is closely associated to milk composition. Metabolomics ...

OBJECTIVE To compare an alternative method to the most probable number (MPN) test for the detection of total coliform present in manually expressed human milk. METHODS 343 samples of manually expressed human milk from flasks donated to the Human Milk Bank of Instituto Fernandes Figueira--IFF were sent to the Laboratory of Food Control of IFF. The samples were used for comparing both methods, ...

BACKGROUND Accurately targeting the nutritional needs of the early preterm infant is challenging when human milk is used due to the natural variation in energy composition. The purpose of this study was to develop and evaluate a simple method for reducing the variation in fat and energy content of human milk prior to fortification such that the infant receives a diet of known composition. MET...

1. Tubercle bacilli were isolated by the Petroff method from 64.8 per cent of the sputa which were found to be positive by the direct microscopic method. 2. The organism was recovered from 69.2 per cent of the samples of milk that were artificially infected. 3. Of the milk obtained through the New Haven Health Department Laboratory 8.4 per cent of the samples were found to contain tubercle baci...
