    Occurrence rate and magnitude of food-related diseases (FRD) are of global concern causing socio-economic issues, and thus, they must be continuously monitored. The objectives of the study were to determine occurrence rate and trends of FRD in Turkey from 1960 to 2010 in parallel to increased rate of population growth. Recorded incidents of foodborne illnesses/diseases were obtained as annual reports and expressed as disease/population rate in order to determine trends of each disease. Long-term evaluations of bacillary dysentery (BD), brucellosis, gastrointestinal diarrhea (GD), meningitis infections, meningitis and central nervous system infections (MCNSI), other bacterial infections, other infections and parasite-caused diseases (OIPCD), other virus-caused infections, paratyphoid, and typhoid showed different trends in terms of occurrence rate but an overall decrease in the occurrence rates of BD, GD, OIPCD, and typhoid.

    It is important to provide sufficient quantity of good quality food for young children. The bases of healthy diet should be learned as a child and nurseries have an important role in shaping the children’s eating habits and forming their taste. This paper summarizes research results about the canteen reform introduced in nurseries on 1st January, 2015. A total of 140 questionnaires were collected from parents or grandparents of the young children attending nurseries in Békéscsaba. We asked them about their pre-reform and post-reform opinions on the children’s food and what they think of the implemented reform. The answers indicated that the parents were satisfied with the nursery caretakers who always gave detailed information about the child’s meal and provided the possibility to discuss problems, most of the parents were well informed about the the nursery canteen reform and the majority agreed with it. Our proposals based on the research are: The parents should have more influence and their opinion should be asked about the catering of their children. Opinions of the nursery caretakers and the catering managers should also be considered, since they spend a lot of time with the young children at the nursery. The changes in the nursery catering should have been implemented more gradually.

    Surface cleaning has an important role in the technology of milling of wheat considering food security. Wheat hardness has an effect on the milling process, it determines the properties, qualities and end use of flours. In the last decade new debranning methods have appeared, which are able to better remove the shell of wheat grains applying rubbing surfaces. In my thesis I examined how different levels of debranning affect hardness and content of ash in wheat types with different grain structure. Conclusion is with approximately 4% of shell removed the hardness of grain. Further removing of shell does not result in further changes though. Reduction of hard wheat’s general grain size with longer debranning process is larger compared to soft wheat’s.

    Membrane separation processes are space and cost-efficient, easy to scale-up operations, which have proved to treat food industrial wastewaters efficiently. Beside the advantages like high separation efficiency without any chemical changes and low energy-intensity, membrane filtration also has drawbacks, like decreased operational efficiency caused by flux decile resulting from fouling and concentration polarization. Combination of oxidation pre-treatment and membrane filtration is a promising method for decreasing fouling due to the physicochemical changes caused by pre-oxidation of the wastewater in structure of colloidal pollutants and in the interactions between the foulants and the membrane material. The aim of this work is to identify the parameters affecting the membrane fouling during treatment of dairy wastewaters, and present the current trends of research in this field.
