Background: Raw (fresh) vegetables are an important ingredient of healthy diet. Many enteric bacterial, parasitic and viral pathogens could be transmitted by vegetables. Mazandaran province is located in northern Iran with a coastal area and extensive fields for vegetable cultivation. The current study is designed to evaluate the parasitic contamination of fresh vegetables.

Methods: A total of 150 samples of fresh vegetables obtained from markets were examined for parasitic infections using standard methods.

Results: Out of 104 samples (60.3%) were contaminated with parasites. Parsley and radish with prevalence rates of 90% (18/20) and 39.1% (9/23) were the most and least contaminated vegetables. Free living larva and Trichostrongylus were the most and least common parasites in our results.

Conclusion: It can be concluded that parasitological contamination of raw vegetables may be a health threat to consumers of such products.

Background: The aim of this study was to investigate the effects of knowledge, attitude and practice of the households on the prevention and control Cutaneous Leishmaniasis.
Methods: This study was a cross-sectional, analytical. The population consisted of the residents in the south of Shiraz. The sample size was 300 and they were selected randomly. For analyzed using the descriptive indices as well as in-depended T-test, chi-square test and ANOVA. The SPSS software 16 was used for analysis.
Results: The mean age of the participants was 36.1±13.6. The mean and standard deviation scores of knowledge, attitude and practice were 16.85 ±3.5, 34.38 ±6.43 and 5.6 ±1.9, respectively. Pearson correlation coefficient showed that the mean awareness (r = 0.13, P-value = 0.02) was more correlated with the mean practice compared to the mean attitude (r = 0.17, P-value = 0.00). However, both variables of knowledge and attitude had a significant relationship with practice (p-value = 0.00).
Conclusion: Generally, the results of our study showed that the scores of knowledge and practice were lower than the mean score, and the attitude score was better than the two other scores.

Background: The aim of this study was to describe the epidemiological characteristics of animal bite during 2011 -2016 years in Jahrom city.
Methods: This cross-sectional study was performed using data from the Jahrom University of Medical Sciences. For analytical statistics, Chi-square test and multiple regression test were used. SPSS software version 21 was used for statistical analysis.
Results: In total, 2010 people with an average age of 31.4 ±1.7 in the years 2011 to 2016 in the were biting. Of these, 429 were female (21.3%) and 1581 were male (78.7%). The results multiple showed that there was a positive correlation between (animal bites; Beta = 0.05, age; Beta = 0.02, location of ulcer; Beta = 0.01) with animal bites positive and direct correlation with animal bites. Animal type variables (Beta = -0.06), primary measures (Beta = -0.03), gender (Beta = -0.03), nationality (Beta = -0.03), wound size (Beta = -0.02) and location (Beta = 0.05) had a negative correlation with animal bites.
Conclusion: Most cases of biting have been related to dogs, pets and rural areas. Therefore, the vaccination of dogs and cats is essential by preventing dogs from being exposed to humans.

Background: Several factors contribute to accidents in small-scale construction projects (SSCPs). The present study aimed to assess the influential factors in SSCP accidents and introduce a model to predict their frequency.
Methods: In total, 38 SSCPs were within the scope of this investigation. The safety index of accident frequency rate (AFR) causing 452 injury construction accidents during 12 years (2007-2018) was analyzed and modeled. Data analysis was performed based on feature selection using Pearson's χ2 coefficient and SPSS modeler, as well as the artificial neural networks (ANNs) in MATLAB software.
Results: Mean AFR was estimated at 26.32 ± 14.83, and the results of both approaches revealed that individual factors, organizational factors, training factors, and risk management-related factors could predict the AFR involved in SSCPs.
Conclusion: The findings of this research could be reliably applied in the decision-making regarding safety and health construction issues. Furthermore, Pearson's correlation-coefficient and ANN modeling are considered to be reliable tools for accident modeling in SSCPs.

Background: Milk is an essential human nutrient, and the monitoring of its sanitation is vital during transportation and storage. The present study aimed to assess bacteriological contamination with Escherichia coli and Listeria monocytogenes in the raw milk samples of the dairy farms in Golestan province, Iran.
Methods: In total, 100 samples were collected from dairy farms in hot and cold seasons. The frequency of E. coli and L. monocytogenes was determined using biochemical tests and polymerase chain reaction (PCR).
Results: The biochemical tests indicated that 28% and 27% of the samples were contaminated with E. coli and L. monocytogenes based on the culture-dependent methods, respectively. In addition, 35 and 40 samples were contaminated with E. coli and L. monocytogenes based on PCR, respectively. PCR had higher sensitivity compared to the biochemical tests (P ˂ 0.05). E. coli and L. monocytogenes contamination was significantly higher in traditional dairy farms than industrial dairy farms (P ˂ 0.05). However, seasonal sampling and geographical region had no significant effects on the contamination load.
Conclusion: According to the results, E. coli and L. monocytogenes were highly frequent in the raw milks samples. However, the microbial loads had no significant differences in hot seasons and traditional dairy farms.
