The objective of the present study was to evaluate the occurrence of Staphylococcus aureus in milk produced in 37 farms located in the regions of Ribeirão Preto and São Carlos, state of São Paulo, Brazil. Two-hundred and eight samples of milk from individual cows showing subclinical mastitis, and 37 samples of bulk tank milk were analyzed. S. aureus strains were detected in 18 (7.3%) milk sampl...

A simple, rapid colorimetric method using label-free Ag NPs (silver nanoparticles) as probe for detection of melamine in raw milk was developed in this study. The assay relies on the fact that melamine can induce aggregation of Ag NPs, and thereby results in their yellow-to-red color change. The concentration of melamine in raw milk can be determined by monitoring with the naked eyes or a UVeVi...

the aim of the present study was to investigate the physico-chemical quality of raw milk of one-humped camel coming from khur and biabanak known as a camel-rearing area located in isfahan province of iran. 500 milliliters of raw milk from thirty individual one-humped camels were randomly collected and subjected for proximate analyses indicating the amounts of total solid, protein, fat, lactose,...

BACKGROUND The quality of dairy products, raw milk in particular, depends on many factors. Low bacterial and somatic cell counts are basic determinants of the appropriate raw milk quality. The objective of the work was to assess the effect of selected factors, that is, the age of cows and their daily milk performance, on cytological quality (somatic cell count) and energy value of milk produced...

Raw milk in southern Ontario frequently contains Yersinia enterocolitica. The potential for transmission of this organism by cheese manufactured from unpasteurized milk was evaluated by examination of milk and cheese curd samples from cheese manufacturing plants and finished cheddar and Italian cheeses. The incidence of Y. enterocolitica was lower in cheese curd samples (9.2%) than in raw milk ...

Milk is widely consumed in Brazil and can be the vehicle of agent transmission. In this study, was evaluated the occurrence of Mycobacterium bovis and non-tuberculous mycobacteria (NTM) in raw and pasteurized milk consumed in the northwestern region of Paraná, Brazil. Fifty-two milk samples (20 pasteurized and 32 raw) from dairy farms near the municipality of Maringa, Parana State, Brazil were ...

Seven very low birthweight (less than 1.3 kg) preterm infants, aged between 3 and 6 weeks were fed raw, pasteurised, and boiled human milk for 3 consecutive weeks. Serial metabolic balance techniques were used to assess the absorption and retention of calcium, phosphorous, sodium, and nitrogen, and the absorption of fat. Fat absorption was reduced by approximately one-third when raw milk was he...

OBJECTIVE To determine, by the creamatocrit measurement, the effect on the fat content of raw and pasteurized donor milk of freezing during 3 months at -20 °C. METHODS The evolution of the creamatocrit measurement (following Lucas technique) on frozen (-20 °C), raw and pasteurized human milk, was analyzed during 3 months. RESULTS The fat content of raw milk (n=44) was 3.19 g/dl at the begin...
