Aflatoxin M1 in Human Breast Milk in Southeastern Turkey
(Springer Heidelberg, 2017) Altun, Serap Kilic; Gurbuz, Semra; Ayag, Emin
This study was performed to determine aflatoxin M-1 (AFM(1)) in human breast milk samples collected in AanlA +/- urfa, located in Southeastern region of Turkey, and to investigate a possible correlation between AFM(1) occurrence (frequency and levels) and sampling seasons. Human breast milk samples collected in December 2014 and in June 2015 from a total of 74 nursing women, both outpatient and inpatient volunteers in hospitals located in AanlA +/- urfa, Turkey, were analyzed using competitive enzyme-linked immunosorbent assay (ELISA) for the presence of AFM(1). AFM(1) was detected in 66 (89.2%) out of 74 samples at an average concentration of 19.0 +/- 13.0 ng/l (min.-max., 9.6-80 ng/l). There was a statistically significant difference between December and June concerning AFM(1) levels (p < 0.05). Further detailed studies will be needed to determine the main sources of aflatoxins in food, to establish protection strategies against maternal and infant exposure to these mycotoxins.

THE EFFECT OF COOKING AND COLD STORAGE PROCESSES ON FLORFENICOL RESIDUES IN MUSCLE TISSUES OF STURGEON (Acipenser gueldenstaedtii) REARED IN BLACK SEA
(Pakistan Journal of Agricultural Sciences, 2021) Gürbüz, Semra; Baydan, Emine; Türe, Mustafa; Taçbaş, Erkan; Akbulut, Bilal; Özcelep, Tuna
This research was performed to determine the effect of boiling, grilling and cold storage processes on florfenicol residues in muscle tissues of sturgeons. A total of 16 sturgeons, 10 of which have received single dosage of florfenicol at 10 mg kg(-1) bw day(-1) level and remaining 6 have not received any florfenicol were used in this study. The analyses were performed by HPLC. The mean recovery rate and repeatability pooled-RSD r% of analytical method for florfenicol analysis of sturgeon muscle were determined as 83.4 +/- 1.07% and 17% respectively. The florfenicol levels were 40.30 +/- 8.23% in the muscle tissue of boiled fish, 57.80 +/- 7.46% in the boiling juice, 101.10 +/- 4.01% in the grilled tissue and 78.01 +/- 15.40% and 62.36 +/- 11.60% in the muscle tissues of fishes, which were stored at -20 degrees C, on the 20th and 50th days respectively. The initial florfenicol level in the fish muscle was significantly reduced (P<0.05) by boiling and cold storage processes. A decrease occurred in florfenicol level in boiling process due to the transfer from muscle tissue to boiling juice, and there was no decrease in the florfenicol level as a result of grilling.

The impact of social media use on restaurant choice
(Anatolia, 2021) Yarış, Ahmet; Aykol, Şehmus
This paper aims to examine the impact of social media use on consumers’ restaurant choices. It presents data from a questionnaire developed for examining social media use and restaurant choice on a trip and home. Exploratory factor analysis was performed to explore the underlying theoretical structure of the phenomena. Four social media use factors were extracted. Then the measurement model and the structural model were tested. Findings show that three social media use factors (searching for services, social interactions, and searching for products) influenced individuals’ restaurant choices on the trip (more) and at home. Based on the results, restaurants should appear more on social media. Restaurants are recommended to share the ambiance, foods, and menus on social media frequently.

(Hindawi, 2020) Gürbüz, Semra; Neslihan Çakıcı, Serdar Mehmetoğlu, Hilal Atmaca, Tahsin Demir, Mukaddes Arıgül Apan, Ömer Faruk Atmaca and Fazıl Güney
This study was performed to investigate the physicochemical quality characteristics of honey produced in Southeastern Anatolia of Turkey. A total of 68 honey samples collected from different beekeepers were analyzed for sugar components, moisture, pH, HMF, electrical conductivity, free acidity, proline values, and diastase number using the methods recommended by the International Honey Commission. The color value was determined by the Hanna HI 96785 color identification device using the Pfund scale. The mean values of fructose + glucose, fructose/glucose ratio, sucrose, and maltose were 70.97 ± 3.27%, 1.21 ± 0.15, 0.90 ± 1.35%, and 2.88 ± 1.42%, respectively. The moisture, pH, electrical conductivity, free acidity, diastase number, proline, and HMF values were 15.91 ± 1.05%, 4.10 ± 0.73, 0.21 ± 0.04 mS/cm, 14.94 ± 6.81 meq/kg, 10.68 ± 4.61, 420±, 174 mg/kg, and 18.5 ± 31.43 mg/kg, respectively. All of the samples met the international standards and legal limits set in Turkey for fructose + glucose, sucrose, moisture, electrical conductivity, and free acidity, whereas 20.58%, 25%, 10.29%, and 8.82% of the samples did not meet the standards and legal limits for the diastase number, proline value, HMF value, and fructose/glucose ratio, respectively. It has been considered to be important to raise awareness of the producer about good production practices and to ensure continuity of inspections for high-quality honey production.

Presence of Staphylococcus Aureus, Staphylococcal Enterotoxins and Antimicrobial Resistance in Traditionally Produced Raw Milk Cheeses
(M H Schaper GmbH CO KG, 2018) Gurbuz, Semra; Keskin, Oktay; Gurbilek, Sevil Erdenlig; Tel, Osman Yasar; Yigin, Akin; Demirci, Mehmet; Hassan, Hala
The objectives of this study was to investigate the presence of Staphylococcus aureus, distribution of classical staphylococcal enterotoxin (SE) SEA to SEE, relevant gene/s and antimicrobial resistance pattern of S. aureus isolated from traditionally produced raw milk cheeses. A total of 106 fresh white cheese samples were examined. The 25 (23.6 %) of 106 cheese samples were found to be contaminated with coagulase positive staphylococci (CPS). From 52 isolates identified as S. aureus, one or more SEs was detected in 38.4 % of the isolates by ELISA whereas one or more se genes were detected in 50 % of the isolates by RT PCR. SEE (75 %) and see gene (61.5 %) were detected most frequently, whereas SED and sed gene were not detected in any isolates. Overall, 63.5 % of isolates were resistant to antimicrobial agents with 59.6 %, 13.5 %, 5.8 %, 5.8 % and 3.8 % of the isolates were resistant to penicillin, erythromycin, tetracycline, cefoxitin and kanamycin, respectively. The results of this study have revealed that cheeses made from raw milk were highly contaminated with S. aureus, therefore, creates a risk for public health due to the presence of enterotoxins as well as resistant strains against antimicrobial agents.
