This study was concerned with the capability of food processors to conduct a product recall, when necessary, with the least time and cost expenditures. An evaluation was made of the effectiveness of the procedures, policies, and organization by which food processors have conducted or would conduct a product recall. Based upon this assessment, a model product recall program was designed to enhance the ability of food processors to conduct product recalls more efficiently. The study concludes that product recalls are very costly to conduct, and, therefore, every effort should be undertaken to prevent situations from occurring which require product recalls. The use of stringent quality control procedures and packaging improvements are thus recommended. Food processors are encouraged to adopt product recall programs in order to reduce the cost of conducting a product recall. If food processors do not take the initiative in these areas, consumerists will likely continue to pressure Congress for more stringent federal regulation of the food industry.

This study addresses the lag in effective usage of scanner-derived information in managerial decision-making. The purpose of this research is to clarify the informational needs of the various levels of management in a retail grocery firm and to develop an informational management system to deliver such information. The four specific objectives of this project are: (1) to identify the decision-making roles of the various levels of management in a firm, (2) to identify the present usage of scanner-derived information in decision-making, (3) to identify specific scanner-derived information which could facilitate the decision-making process, and (4) to develop a firm-wide information management system which would provide each management level with the information it needs and would coordinate total firm operations, but would not burden a particular level with large volumes of unnecessary data. The information used for meeting the objectives of this research was largely collected through open-ended discussions with various levels of management within seventeen cooperating retail grocery firms. The discussions placed emphasis on the current usages of scanner-derived data and on how to facilitate the use of scanner-derived data in managerial decision-making. This research substantiated the hypothesis that little use had been made of scanner-derived data for managerial decision-making in retail grocery firms. Also, barriers to the effective use of scanner-derived data were documented. The specific informational needs of the various levels of management, as discovered through the discussions with managers of the cooperating firms, were used as the basis for the information management system. / M.S.

The purpose of this investigation is to determine through routine checks the number of organisms present in the various raw ingredients used for the preparation of foods. The problem has consisted of, first, a determination of the total bacterial population by numbers; second, a determination of the incidence of colon bacteria in the samples examined; third, a determination of the presence of yeasts and molds; and fourth, an attempt to utilize this information obtained in judging the methods of handling the raw ingredients before they are used in the processing of foods.

It is essential for both employers and employees to know and understand their obligations and rights about occupational health and safety. The study aimed at developing guidelines for the managers of health and safety programmes to promote compliance with OHS Act (No. 85 of 1993) among the food and beverage industry in South Africa. The study sites were from the four selected provinces of South Africa, with twenty three of them located in the Gauteng Province. A quantitative research method which is descriptive in nature was used to obtain in-depth knowledge on compliance to the health and safety legislation. Data was collected from 27 study sites using an inspection checklist and an interview- led questionnaire for the 202 employees. Data was analysed using the Statistical Package for the Social Sciences (SPSS) version 21. Most employees on the study sites were young and therefore needed regular supervision, information, instruction and training to promote safe work and reduce injury and diseases. The study sites were male dominated. It emerged that there was general lack of consultation and communication with regards to health and safety matters between the employers and the employees. It was also noted that most study sites did not have a written and conspicuously placed health and safety policy and the OHS Act No. 85 of 1993. Majority of the study sites did not deploy adequate resources to manage problems related to health and safety at work and reduce their incidence. In addition, employees experienced injuries or illnesses at one point or the other as they were exposed to various occupational hazards. Finally, most study sites had poor housekeeping practices. Employers did not have the appropriate control measures, such as baseline risk assessments, in place. This placed employees at an increased risk of injuries and illnesses as well as the possibility of employers facing financial burdens such as higher compensation claims, medical specialist fees, fees involved in the replacement of injured employees or fees for the recruitment and training of new recruits. / Health Studies / D.

Thesis (MTech (Engineering))--Cape Peninsula University of Technology, 2008 / While there is a standard for quality and environmental auditors, there is no local or international standard for food safety auditing, which means auditors from different certification bodies can use their own discretion when auditing food establishments. There is a requirement to investigate the quality of work performed by South African food safety auditors. in order to establish whether they do in fact add value when conducting registration and certification audits. This is also an indication of the importance of improving and maintaining a high standard of food safety in the food services industry. The overall concept of food safety in South Africa IS clearly not defined. understood by only a few consumers, and not widely accepted. Research has shown that food retailers in South Africa in general do not believe food safety auditors are competent. In the wake of the Sudan Red scare two years ago. a long awaited food safety initiative was launched in February 2006. The scare pertaining to a carcinogenic food dye. which found its way into spices on local supermarket shelves, mobilized food industry role players to improve food safety standards. Under the auspices of the Consumer Goods Council of South Africa (CGCSA), the body responsible for establishing best practices and implementation standards, Food Safety South Africa (FSSA) will enable an organization to determine the exact nature and extent of possible and actual problems along the food supply chain. The key objectives of this research study are to determine whether one food certification standard is needed in South Africa and to assess the value added by the food auditors to their clients. Social research will be conducted within the ambit of the dissertation, with case study serving as research method. Both quantitative and qualitative research paradigms will be used to gather data for the research survey in support of the research question. forming the crux of the dissertation which reads as follow: "How can food safety auditors increase value added to the audit process in food environments in South Africa?"

A macroscopic model describing the main physiological phenomena observed during the fed-batch baker’s yeast production process and including the influence of nitrogen on the key bio-mechanisms is proposed. First, on the basis of a set of biological reactions, inspired by the model of Sonnleitner and Käppeli, a model in which the nitrogen and glucose consumption are coordinated is proposed. Second, an attempt of estimating storage carbohydrate contents in yeast cells through an extension of this model is presented. The model is identified and validated with experimental data of fed-batch yeast cultures and successfully predicts the dynamics of cell growth, substrate consumption (nitrogen and carbon sources) and metabolite production (ethanol and storage carbohydrates). <p><p>The developed model was used for the determination of optimal operating conditions, in the sense of a production criterion. To this end, two different approaches were used: a control vector parameterization approach and a semi-analytical formulation of the optimal operating policy. The two approaches were compared with numerical and experimental data. The results of the two approaches lead to the determination of similar optimal operation conditions, which have been implemented for a new experimental phase. Moreover, these optimal conditions are in agreement with the profiles obtained by industrial manufacturers through an empirical optimization of the process.<p> / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished
