The high incidence of colon cancer in affluent societies has often been attributed to a high fat diet and, more in particular, the consumption of meat. The association of the consumption of meat and the intake of fat with risk of colon cancer was investigated in a prospective cohort study on diet and cancer, which is being conducted in the Netherlands since 1986 among 120,852 men and women, age...

The high prevalence of vitamin B-12 deficiency in many regions of the world is becoming recognized as a widespread public health problem, but it is not known to what extent this deficiency results from a low intake of the vitamin or from its malabsorption from food. In rural Kenya, where a previous study identified a high prevalence of inadequate vitamin B-12 intakes, this study examined whethe...

Foodborne pathogens have the main concern in public health and food safety. Bacillus cereus food poisoning is one of the most important foodborne pathogens worldwide. In the present study, a total of 200 random beef product samples were collected from different supermarkets located at Menofia and Cairo governorates were examined for the presence of B. cereus. In addition, the presence of some v...

The Shiga-like toxin-producing escherichia coli (STEC) is the most important group of food-borne pathogens that emerged recently. These bacteria can cause severe health problems in humans like diarrhea, hemorrhagic colitis and hemolytic uraemic syndrome which have become a serious health problem in various countries. Cattle are thought to be a reservoir for e. coli STEC, and many foodborne dise...

A procedure combining enrichment surface adhesion and polymerase chain detection (SA-PCR) was developed and applied in the detection of Listeria monocytogenes in meat products. Minced beef samples were inoculated with L. monocytogenes (log(10)3 cfu g(-1)) and incubated for 10 h at 30 degrees C in buffered peptone water. L. monocytogenes was recovered from the culture by attachment to a polycarb...

To detect food E. coli O157:H7 contamination rapidly and accurately, it is essential to prepare high specific monoclonal antibodies (mAbs) against the pathogen. Cyclophosphamide (Cy)-mediated subtractive immunization strategy was performed in mice to generate mAbs that react with E. coli O157:H7, but not with other affiliated bacteria. Specificity of 19 mAbs was evaluated by ELISA and/or dot-im...

Background: Beef burgers made in Iran contain various compounds such as meat, cereals flour, as well as some spices which can be contaminated to Bacillus cereus, causing gastroenteritis in the consumer. This study is focused onoccurrence of B. cereus in beef burgers marketed in Tehran, capital of Iran. Methods:  In this cross-sectional study, a total of 80 samples of different types of be...

This study was an attempt to devise productive orientations of cattle herds in eastern high plains of Algeria. In this regard, 165 farms randomly identified were investigated. The selection of breeders was based to existence of cattle on the farm, and the farmer proposed to investigation must have at least two cows. The approach taken was to identify all systems adopted by farmers in a region t...

In this study, hydrolyzed protein as a natural preservative for increasing the shelf life of minced meat of silver carp (Hypophthalmichthys molitrix) was used in a refrigerator for 12 days. Hydrolyzed protein was added to the minced meat of fish, at 0.5, 1 and 1.5% concentration. In this regard, microbial, chemical and sensory tests were carried out during the period of storage at intervals of ...

Quality of minced silver carp (Hypophthalmicthysmolitrix) with gum arabic encapsulated with 1 and 1.5%( w/w) and rosemary extract (RE) (1 and 1.5% w/w) stored at 4˚C was studied chemically (peroxide value and total volatile nitrogen) and microbiologically (total viable count, psychrotrophic count) analyses. The efficacy of the encapsulated extract to control the population of Esche...
