Influence of transportation on quality of delivered food (Experience of boarders)
ŽUFOVÁ, Pavlína
In this bachelor thesis I deal with the influence of transport on quality of distributed food with focus on experience of the boarders. The paper is divided into a theoretical and a practical part. The theoretical part is concerned with the HACCP system representing the preventive measures that serve for provision of health harmlessness of food in processes related to its production, treatment, storing and transport. This system is required as a part of every catering establishment. The work analyses the legislation and is concerned with duties of the operators and the persons who carry out epidemiologically serious activities while it focuses on the maintenance of their personal hygiene. In the final work I point out the potential but in fact threatening health danger of food. I classify these food risks and suggest some possibilities of elimination of such risks. The final work studies the alimentary infections that are caused mostly by wrong technological treatment or ignoring the hygienic rules. In the work I introduce and point out the hygienic requirements that should be respected, followed and fulfilled in the process and preparation of food. I further describe transport wrapping, transport of food itself and the rules of food delivery and its serving. In the practical part I use the theoretical findings from the first part of this bachelor thesis. In this part I make a brief description of the main university canteen. The K2 refectory is described in more details and I analyse the process from filling into the food containers to the process of serving the food. Simultaneously, I emphasize the temperature of particular dishes that has to be kept during the transport as well as during the process of serving. For comparison and evaluation of the results I chose a quantitative research method. This method was realised in a form of a questionnaire. I distributed the questionnaires personally to the students of the Faculty of Health and Social Studies, in building of which the K2 refectory is placed, and the students addressed near the main university canteen. The questionnaire was anonymous and contained 21 close-ended questions. Both research samples received the same questionnaires that differed only in the sequence of particular questions. In total, 220 questionnaires were handed out, 110 in each place. The percentage of questionnaires returned was 100 %. Considering the fact that I eliminated two questionnaires from the K2 refectory and five questionnaires from the main university canteen due to their wrong completing, the real percentage of questionnaires returned in the K2 refectory was 98 % and in the main university canteen 95 %. The particular data obtained in the questionnaires were further processed in Microsoft Office Excel and Microsoft Office Word. The aim of this work was to chart the experience of the boarders in the K2 refectory who consume fresh, although delivered food. The process of transportation could debase food therefore the quality of food might decrease. The experience of these students were subsequently compared with the experience of students who board in the main university canteen where the food is prepared (cooked) and consumed immediately. Based on two main goals, I determined three hypotheses: Hypothesis number 1: Transportation of food has negative influence on the sensorial qualities of food. On the basis of the statistical testing, this hypothesis was rejected. Hypothesis number 2: Students prefer fresh food. After the statistical testing, this hypothesis is valid. Hypothesis number 3: Students do not feel the difference between fresh and delivered food. This hypothesis is valid as well. The results gained and processed during my research will be presented to the university canteen staff that could use the findings in practice.

Comparison of knowledge of Secondary Hotel School students in České Budějovice and Teplice on hygiene and sanitary requirements in catering services
WEISSOVÁ, Veronika
Students of secondary hotel schools are the most likely candidates to work in catering services because of their professional specialization. Graduates may work in the hospitality or hotel industry and are qualified for a job in catering and should be able to ensure compliance in hygiene, health and safety at work. This work is focused on students of the secondary hotel schools and their awareness of hygiene requirements in food services. The work is divided into two parts. The theoretical part defines catering service, its features and types. It also includes the legislation relating to hygiene requirements in food industry, describes the spatial requirements for businesses, personal and operational hygiene and the HACCP system. The work also briefly describes different ways of food preparation and possibilities to influence health safety and the most common foodborne infections in catering services caused by failing to comply with correct manufacturing and hygiene principles. This work describes sanitation (disinfection, insect and rodent control) and the performance of state health supervision of food hygiene. The practical part includes research results which were obtained by a quantitative questionnaire method. Questionnaires were distributed amongst students of third and fourth (the final) years of secondary hotel schools in České Budějovice and Teplice. Each questionnaire contained 25 closed questions; the data collection was conducted anonymously. 106 of the 110 distributed questionnaires were returned from the Secondary Hotel School in České Budějovice. 99 questionnaires were sufficiently filled in to meet the research needs, making the return of 90%. In the Secondary Hotel School in Teplice, 98 of the 100 distributed questionnaires returned, 96 were sufficiently filled in, making the return of 96%. The aim of this work was to determine the level of awareness of the hygiene requirements in food service at secondary hotel schools in Teplice and České Budějovice. Based on the objectives of the work I set two hypotheses. Hypothesis 1: Students of secondary hotel schools in Teplice and České Budějovice are not informed about hygiene requirements in food services. Hypothesis 2: Students of secondary hotel schools in Teplice and České Budějovice who are interested in working in catering services are informed about hygiene requirements for food services more than students who are not interested in such work. After testing the two hypotheses it is evident from the results that the students of secondary hotel schools in Teplice and České Budějovice are not informed about hygiene requirements in food services and that students of secondary hotel schools in České Budějovice and Teplice who are interested in working in catering services are more informed about the hygiene requirements than students who do not intend to work in the field. Based on these findings, it is important to educate students of secondary hotel schools continually, especially about the foodborne disease issues and also, to motivate them to work in catering services, because there are more than 50% of students who do not want to advance towards working in the industry at both schools. There was almost no difference between the knowledge of students in secondary hotel schools in Teplice or České Budějovice. Students of the Secondary Hotel School in České Budějovice were slightly better an the number of correctly answered questions. Only one question, concerning the E-coli outbreak in Germany, was correctly answered by most students in Teplice. This work could serve as a teaching resource improving knowledge in this field. The outcome of this work is a flyer for the secondary hotel schools students.

Information Caterers on Hygiene Requirements for Food Services
ANDRÁŠIKOVÁ, Nikoleta
The present time offers a large number of catering services. The trend of the present time is not to eat at home. People have too little time to pre-pare their meals at home and for this reason they often utilize public alimentation ser-vices (e.g. in restaurants, pizzerias, snack bars, bistros). However, this thesis is not focused on the consumer of these services but on the operator providing these services. The thesis is subdivided into two parts. The theoretical part includes a short description of the development of catering services and gastronomy, the general description of HACCP-Hazard Analysis Critical Control Points system and its contribution in practice. Moreover the state medical supervision is mentioned here in the scope of the hygiene of nutrition, spatial requirements on cater-ing services, legislation as well as various types of illnesses caused by failure to observe the correct production and hygienic principles. The thesis describes also the prevention, disinfection, disinfestation and rodent control. In the practical part, the data acquired by means of questionnaires are evaluated. The questionnaires were distributed personally, mostly directly into the hands of cater-ing service providers handed over through their employees. The target of the thesis was to find out the information and knowledge level of the operators of catering services in České Budějovice with regard to hygienic requirements on catering services. I ascer-tained whether the providers of catering services have elaborated procedures based on HACCP principles and whether they have a basic knowledge in the field concerning the hygienic requirements on catering services. The results show that the providers of catering services in České Budějovice have elaborated procedures based on HACCP principles. The general knowledge in nutrition hygiene of the catering service providers turned out to be average. The catering services constitute an important activity from the epidemiological point of view and for this reason the knowledge of operators in the field of nutrition hygiene should be on a higher level than up to now. This thesis is suit-able as study material for the catering service providers, to improve their knowledge in this field.
