An understanding of the ecological factors that regulate natural populations of Aedes aegypti mosquitoes can improve control and reduce the incidence of dengue (DF) and dengue hemorrhagic fever (DHF) in tropical areas. We investigated whether immature Ae. aegypti in water-storage containers from an urban area were under food limitation. We used starvation resistance (number of days alive withou...

Currently, due to their beneficial effects, there is interest in adding prebiotics to food products. Thisstudy investigated the effect of the addition of inulin (1% and 2%) on microbial and physico-chemicalproperties of probiotic low fat yogurt manufactured with Lactobacillus acidophilus. Six experimentalpreparations of yogurt were produced. Homogenized, standardized and pasteurized low fat mil...

Background and Objectives: Production and consumption of freshly-cut fruits have been increased in recent decades.  One of the major problems in storage of freshly-cut fruits, the color change, is a result of the oxidative reactions of phenolic compounds by polyphenol oxidases. Various treatments such as coating and refrigeration are used to improve quality and shelf-life of the fresh-cut fruit...

Outbreaks of Salmonella contamination of peanut butter have become a serious food safety concern for consumers. Based on the recent studies on peanut butter storage periods and storage methods, we aim to investigate how temperature and light affect the bacteria growth on generic brands of peanut butter. Our results indicate strong temperature and light effects on bacteria growth and the two mai...

BACKGROUND The objective of this study was to describe the epidemiology of foodborne disease outbreaks in schools and to identify where preventive measures could be targeted. METHODS Reports by state and local health departments of foodborne disease outbreaks occurring in primary and secondary schools, colleges and universities from January 1, 1973, through December 31, 1997, were reviewed. D...

Physical-mechanical properties of egg constituents and their modifications during storage and poststorage greatly influence the efficiency of food processing, such as the separation of white and yolk by mechanical shelling. Thick albumen height, Haugh unit, yolk index and vitelline membrane-yolk system strength of eggs from Hy-Line White and Lohmann Brown hens were analyzed during 7 mo of stora...

The effects of different concentrations of Zataria multiflora  essential oils at concentrations of 0, 0.005, 0.015, 0.045, 0.135, 0.405 and 0.810% on the growth of Staphylococcus aureus were studied in a food model system, light salted fillets of silver carp (Hypophthalmichthys molitrix) at storage temperature of 10ºC for 21 days. The results showed that there was no significant difference in b...
