Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has s...

materials and methods: a total of 285 commercial and traditional dairy products as well as 267 pasteurized and raw milk samples were collected during one year. the samples were studied by culturing and the positive-culture samples were investigated using pcr techniques. results: the results of culture showed that 52 (9.42%) and 28 (5.07%) of the total 552 milk and dairy samples were positive fo...

BACKGROUND The aim of this research was to observe the changes which take place in the electrophoretic picture of milk proteins after pasteurisation and inoculation with different starter cultures (both traditional and probiotic). After incubation, the yoghurt, kefir, acidified milk, fermented Bifidobacterium bifidum drink and Lactobacillus acidophillus drink were chilled for 14 days to observe...

The incidence of contamination of aflatoxin M1 (AFM1) in milk samples collected from the Jordanian market was investigated by using the competitive enzyme linked immunosorbent assay (ELISA) technique. A total of 175 samples were collected during 2014-2015. All tested samples were contaminated with various levels of AFM1 ranging from 9.71 to 288.68 ng/kg. The concentration of AFM1 in 66% of fres...

Introduction: Aflatoxins, known as causative factors of hepatic and extra-hepatic carcinogenesis within humans, are extremely teratogenic, mutagenic, toxic, and carcinogenic compounds. Materials & Methods: This study was undertaken to determine the occurrence of aflatoxin M1 (AFM1) in 40 raw milk and 47 pasteurized milk samples collected during spring and winter. In order to analyze the samp...

Independent risk factors for campylobacteriosis (eating raw, rare, or undercooked poultry; consuming raw milk or raw milk products; and eating chicken or turkey in a commercial establishment) account for <50% of cases in Quebec. Substantial regional and seasonal variations in campylobacteriosis were not correlated with campylobacter in chickens and suggested environmental sources of infection, ...
