The effect of pasteurization on survival in milk of four strains of psychrophilic pseudomonads and of one strain of Alcaligenes was determined. Cell numbers were very low immediately after pasteurization, but increased after storage. The survival of psychrophilic bacteria in pasteurized milk appeared to depend on the initial number of organisms, and detection depended partly on the length of ti...

Human milk is the ideal food to nourish newborn babies; it contains important nutrients: proteins, carbohydrates, fat, vitamins and minerals, which are needed to provide agood health to the infants. Milk fat provides about 50% of energy to infants and its fatty acids are essential for brain and retina development. Therefore, analysis of the lipid fraction of human milk is an important task, esp...

     The aim of this study was to evaluate aflatoxin M1 (AFM1) contamination in pasteurized milk samples in Mashhad, Iran. One hundred and ten milk samples from different supermarkets were collected during three months in spring and investigated by Enzyme Linked Immuno Sorbent Assay (ELISA). AFM1 was found in 100% of the milk samples. About 5.4% of the samples c...

The number of human milk banks is increasing worldwide. Although the beneficial effects of feeding premature infants with their mother's milk are well documented, less is known about the effects of feeding these infants with pasteurized donor milk. We propose a randomized trial comparing the effects of a 100% human milk-based diet (human milk supplemented with a human milk-derived fortifier) an...

PURPOSE Extremely low birth weight infants (ELBWIs) have a high risk of acquiring cytomegalovirus (CMV) infection via breast milk and consequently developing serious symptoms. We evaluated whether freeze-thawing or pasteurization could prevent postnatal CMV infection transmitted through breast milk in ELBWIs. MATERIALS AND METHODS Medical records of 385 ELBWIs with whole milk feeding, and fre...

Milk consumption in the semi-arid regions of Kenya is not well understood. A study was carried out on consumption of milk and milk products in the semi-arid region of eastern Kenya. A total of 135 rural and 126 urban households were interviewed. Raw milk was the most popular and was consumed by 99% and 84% of rural and urban households, respectively. Generally as degree of processing increased,...

OBJECTIVE The objectives of the present study were to determine the prevalence of potentially pathogenic microorganisms that indicate the hygienic and sanitary conditions of human milk samples collected at a Human Milk Bank. METHODS Three hundred and thirty eight (338) samples of human milk collected from a milk bank in a maternity in the municipality of Goiânia, in the state of Goias, Brazil...

ATP-bioluminescence assay was used to evaluate the cleaning and sanitizing procedures of stainless steel milk contact surfaces. Surfaces of a raw milk transportation tank, a raw milk cooling storage tank, an equalization pasteurizing tank, a pasteurized milk storage tank and a pasteurized milk packaging tank, as well as a milk centrifuge were evaluated. The Relative Light Unit (RLU) using a com...

Background and Objectives: Pre-requisite programs (PRPs) are “primary conditions and requirements essential for HACCP operations, which are crucial in food safety programs”. The present study was conducted to evaluate the impact of implementation of PRPs on the microbial parameters of pasteurized milk (according to the National Standard of Iran). Effectiveness of HACCP operation req...
