Abstract: In this study the quality properties of Yemeni honeys were investigated. Two types of honey, monofloral (Sidr) and multi-flora honey originated from three different regions in Yemen (Hadramout, Dhamar and Amran governorates), were included in this study. Honey samples were collected and analyzed to determine their physicochemical properties such as (moisture content, total soluble solid (TSS), pH, free acidity, reducing sugars, sucrose, vitamin (C), electrical conductivity (EC), refractive index, water insoluble matter (WIM) and density) and to determine effect of geographical area and botanical source on the physicochemical properties of honey. The results showed that moisture content (18.63%±1.39), total soluble solid (TSS) content (79.58±1.42°Brix), pH (4.26±1.17), free acidity (17.16±5.56 meq/kg honey), reducing sugars (63.86%±3.50), sucrose content was (4.4%±1.12), total sugar (68.27%±3.55), vitamin C (0.65±0.226 mg/100g), the electrical conductivity (EC) (731.08±273.87μS/cm), refractive index (1.4958±0.0038), while water insoluble matter (WIM) was (0.092%±0.033) and the density was (1.3871±0.035 g/cm3). Results obtained from this study showed that honey samples coincide with those specified by Yemeni standard organization (YSMO) and Arabian Gulf standard organization (GSO). Botanical source affected on the pH, sucrose content and the electrical conductivity (EC) values of honey, which was higher in Sidr honey than multi floral honey samples. The geographical area caused a variation in the moisture, free acidity and vitamin C content of honey, while other physicochemical properties for honey had a negligible variation between honey from the different regions and botanical sources.

Abstract: Providing access to food around schools constitutes an important part of nutritional environment of children and adolescents. This study intends to determine the proximity of food outlets to secondary schools in the center of Gaziantep, the presence of hawkers and whether there are differences according to socio-economic zones. In this qualitative study, schools were chosen according to the socioeconomic status of the neighborhoods. The data were recorded by investigators through on-site observations. Boiled corn in cups, single cigarette as well as vendors of snacks, fruits, fried chips, ice cream, sweets and beverages were being sold in the vicinity of all the schools. It was observed that about one quarter of the students went to the various shops and hawkers at the end of the school day. The socioeconomic status of a neighborhood had no impact in terms of the variety of products sold. Price of boiled corn sold in cardboard cups of the same size varied between TRY 1-2 (0.26-0.52 USD) according to the income level of the neighborhood in which it was sold. Despite the current legislation in our country, sales of single cigarette to those under 18 are still a cause for concern. It is necessary to take measures for controlling the access of school children to unhealthy food and non-food products.

Abstract: Objective: To quantitatively detect Salmonella in raw pork, obtain the data of Salmonella contamination in raw pork, conduct risk assessment and formulate reasonable risk management measures. Methods: 302 samples of fresh pork were collected from 10 of Jilin province, mainly from agricultural markets and supermarkets. A 12-tube MPN method was used for quantitative detection of Salmonella, and biochemical identification of API20E and serological identification of Salmonella. Sixty-nine strains of Salmonella were detected. Results: The total detection rate of Salmonella was 22.8%. Sixty-nine strains of Salmonella were divided into 20 serotypes, mainly S.Typhimurium, accounting for 33.3%, followed by S. London (13.0%) and S.Rissen (8.7%). The positive samples were mainly concentrated in the 3rd quarter, followed by the 2nd and 4th quarter, and the quantitative results of Salmonella were between 0.015MPN/g and 600 MPN/g, focus on 0.215MPN/g. Conclusion: The detection rate and contamination in raw pork were serious. Serotypes include both common and rare serotypes. The contamination level of samples collected from farmers’ markets was higher than those from supermarkets and online shopping. The detection level in the third, second and fourth quarters was higher than that in the first quarter, it means that high temperature is beneficial to breeding bacteria. The detection rate of samples collected from urban and rural areas showed that the contamination of raw pork Salmonella was not affected by the environmental hygiene conditions, mainly from the samples themselves.

Abstract: Objective: To detec integron genes and the drug resistance of two foodborne salmonella from different sources in Jilin Province, explore the correlation between drug resistance and integron. Method: The minimum inhibitory concentration (MIC) method was used to detect drug resistance of 278 salmonella strains in Jilin Province. Real-time PCR was used to detect type I, II and III integron genes, and the correlation between drug resistance and integron gene carrier rate was compared. Result: The total drug resistance rate of 278 strains of food-borne Salmonella was 89.57% (249/278). The positive rates of type I integron, type II integron and type III integron were 51.44% (143/278), 4.32% (12/278) and 14.39% (40/278) respectively. The drug resistance rate of foodborne disease samples was 95.8% (207/216), type I integron was 58.8% (127/216), type II integron was 5.56% (12/216), and type III integron gene was 17.59% (38/216). The drug resistance rate of food (meat, egg) samples was 67.7% (42/62), type I integron was 25.81% (16/62), type III integron gene was 3.23% (2/62), and type II integron gene was detected. Conclusion: Through the surveillance of Salmonella drug resistance and Integron gene carrying rate in food safety risk surveillance and food-borne disease surveillance in Jilin Province, The gene carrying rate of type I and III Integron of Salmonella from food-borne diseases was significantly higher than that of food (meat and eggs). Integron gene system plays an important role in drug resistance transmission of foodborne pathogens. It is suggested that attention should be paid to the monitoring of salmonella drug resistance to ensure food safety and human health.
