Abstract
A study was carried out to estimate the prevalence of Coagulase – Positive Staphylococcus aureus in milk collected in the milk collecting center in Garmsar city. Ninety-six raw milk samples (84 composite samples and 12 bulk samples) were collected from Garmsar milk collecting center. Raw milk samples were transferred to laboratory in safe conditions. After serial dilution, the appropriate concentrations (10 -2 to 10 -6) were cultured on Baired- Parker agar medium. The plates were incubated at 37 oC for 2 days (48h). After 48 hours' incubation, the colonies with black centers and light areas were used for staphylococcal assay. The coagulase test was done with rabbit plasma and coagulate- positive colonies were then counted. The results showed that mean counts of coagulate-positive Staphylococcus aureus in composite and bulk milk were 5.4 ×10 5 cfu/ml and 3.2 × 105 cfu/ml, respectively. The counts ranged from 8.6 × 10 4 to 2.1 × 10 6 cfu/ml and 1.4 ×10 5to 5.5 × 10 5 cfu/ ml. The standard deviations were 3.5 × 10 5 cfu/ml and 1.4 × 10 5 cfu/ml respectively. It is clear that the milk collected at this facility was rather heavily contaminated with S. aureus. Therefore, it may constitute a health hazard because of the possible production of enterotoxin in the milk consumed by the people. In order to reduce staphylococcal contamination in milk, it is recommended to treat cases of clinical and subclinical staphylococcal mastitis in livestock. Also, it is necessary to use hygienic procedures during the production process as well as transportation and storage.

Abstract
Background and Aim: Attitude, as the most important social psychology concept, has a special place in research; undoubtedly, in university life having a positive attitude is essential for success in any field of study. The aim of this study was to determine tha attitude of food safety and hygiene students toward their field of study and future career in the Iranian universities of medical sciences.
Materials and Methods: This was a descriptive cross-sectional study, conducted in 2016, including 77 food safety and hygiene students in the Iranian universities of medical sciences, selected by census. Data were collected using a questionnaire containing 24 questions and analyzed by SPSS-24 software, the statistical tests being descriptive statistical tests.
Results: The attitude score (Mean ± SD) of the students toward their field of study was
35.0 ± 12.4, indicating that they had a positive attitude, while the score of their attitude toward future career was 23.05 ± 10.86, which was less than acceptable. Further analysis of the data showed a significant association between the students’ attitude toward their field of study and employment status (p = 0.036).
Conclusion: Based on the results of this study, the food safety and hygiene students have a positive attitude towards their field of study, while their attitude toward future career is lower than acceptable, which demonstrates lack of a desirable attitude. Strengthening of training programs and advice and support for the students can play an effective role in reinforcing their attitude.

Abstract
Safe food and proper nutrition play a vital role in the health of populations. Food-borne diseases are a serious public health problem. Food handlers working in the kitchen play an important role in the transmission of foodborne diseases. Food-borne diseases, especially those caused by bacteria, viruses, parasites and fungi, are preventable. Proper manpower training is a key factor in provision of safe food and prevention of malnutrition.
Materials and Methods: A descriptive, cross-sectional and applied study was conducted in 10 hospitals affiliated with Tehran University of Medical Sciences in 2017. The knowledge, attitude and practice of 136 food handlers working in the kitchens of the hospitals was assessed using questionnaires.
Results: Analysis of the data showed that 8.08% of the participants had a good knowledge about food hygiene and safety (a score above 75%), while 16.7% of them achieved the full score as regards attitude. The hospitals’ performance was at a desirable level. The level of food hygiene and safety knowledge of the food handlers was significantly associated with their refresher trainings (p <0.05).
Conclusion: It can be concluded that the awareness of food handlers in most of the hospitals about food hygiene and safety is not sufficiently high. It is suggested to design and implement proper refresher training crash courses, as well as sensitize the personnel.

Abstract
Background and Aim: Considering the needs of the society food safety and hygiene graduates can be employed in positions related to their field of study and provide services to solve the food safety and hygiene problems at the community level. The aim of this research was to explain the current situation and future prospects of the food safety and hygiene field in terms of occupational positions and the needs of the society.
Materials and Methods: A descriptive and applied study was conducted with the time series analysis method regarding the current situation and the future perspective of the food safety and hygiene field in terms of occupational positions and the society's need. A valid and reliable questionnaire was developed and used for data collection. In order to predict the future of the field, the time series statistical analysis method (Autoregressive integrated moving average =ARIMA) was used. In addition, its strengths, weaknesses, opportunities and threats were identified and analysed using the SWOT qualitative content analysis.
Results: Analysis of the data obtained showed that the number of food safety and hygiene graduates has an increasing trend. The proportions of the graduates in relevant occupations, in non-relevant occupations and out of job were 48.00%, 24.75% and 27.25%, respectively. The data also revealed that this field of study had good strengths, so attempts should be made to increases them, reducing the weaknesses and threats, using the available and potential opportunities.
Conclusion: Based on the findings of this study the numbers of individuals accepted and graduated in the field of food safety and hygiene have an increasing trend, which are expected to continue in the next ten years. On the whole, the current moderate situation and the future perspective of the food safety and hygiene field in terms of the occupational positions and the society's need can be relatively favourable. In any case it is essential to make serious attempts continuously to maintain and promote this field of study.
