Infant mortality rate is an indicator of public health and social welfare (Preston 1975; Haines 1985, 2011; Lee 1991). In the US and some European countries, urban infant mortality rates have been gradually declining since the middle 1800s. Several factors accounted for this trend, e.g. the economic growth, improved public sanitation and medical provisions, spread of child care knowledge, and b...

An improved extraction and HPLC method for the simultaneous extraction and quantitation of retinol, α-tocopherol, α-tocotrienol and β-carotene was developed to analyze commercial whole/semi-skim/skim samples of raw/pasteurized/UHT milk in transparent plastic/glass bottles and Tetra Brik containers. The sample preparation method required prior saponification at 40oC for 15 min followed by n-hexa...

The beneficial effects of human milk extend to the feeding of premature infants, because their nutrition support must be designed to compensate for metabolic and gastrointestinal immaturity, immunologic compromise, and maternal psychosocial conditions. Significant effects on the recipient host, such as reduction in sepsis and necrotizing enterocolitis, have been reported for premature infants f...

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of paratuberculosis, a disease with considerable economic impact, principally on dairy cattle herds. Animals with paratuberculosis shed viable MAP especially in their milk, faeces and semen. MAP may have a role in the development of Crohn’s disease in humans via the consumption of contaminated milk and milk products. The c...

Three strains of Yersinia enterocolitica isolated from milk had D values at 62.8 degrees C from 0.24 to 0.96 min and z values of 5.11 to 5.78 degrees C. Since the pasteurization processes for dairy products recommended by the Food and Drug Administration are adequate to destroy large concentrations of these organisms, Y. enterocolitica in pasteurized milk probably results from substandard proce...

the purpose of this survey was to evaluate natural occurrence and content of aflatoxin m1 (afm1) in dairy products marketed in urmia (iran). during september 2007, 40 samples of pasteurized milk, 40 samples of ultra high temperature treated (uht) milk, 40 samples of creamy cheese and 40 samples of iranian feta cheese were collected from different supermarkets in urmia city. afm1 contents were d...

and Implications Pre-ruminant Holstein bull calves were fed two diets of pasteurized whole milk (PWM) in amounts that either limited intake or that maximized intake according to common commercial practice. Diets then were either supplemented or not supplemented with a full complement of vitamins and trace minerals (VTM) that met or exceeded NRC requirements. The objective of the study was to qu...
