هدف البحث الحالي إلى دراسة تأثير مراحل التداول على الجودة و السلامة الصحية لسمك البراق Dicentrarchus labrax. جمعت العينات السمكية من المياه البحرية لمحافظة طرطوس, و تمت متابعتها من لحظة صيدها مروراً بأماكن تسويقها و حتى وصولها إلى المستهلك, و أجريت لها الاختبارات الحسية و الميكروبية في كل مرحلة, كما قيست بعض الخصائص الفيزيائية و الكيميائية للمياه في منطقة الصيد. بينت نتائج الدراسة تدرّج جودة الصفات الحسية لأسماك البراق, إذ كانت جيدة لحظة الصيد , و تراجعت تبعاً لمراحل التسويق, و بدأت بالتدهور و الانخفاض في ساحة السمك. كما دلت النتائج على ازدياد التعداد العام للميكروبات (الحمولة الجرثومية) تبعاً لمراحل التداول, و كان أعلاها في ساحة السمك بالمقارنة مع باقي المراحل, إذ كانت الزيادة بما يقارب ضعف التعداد العام لها في لحظة الصيد, و استمر بالازدياد في محلات البيع للمستهلك . و قد لوحظ هذا الازدياد في فصل الصيف , و بشكل أقل في فصل الربيع, و كانت الغلاصم الجزء الأكثر تلوثاً و تأثراً بعملية التداول, يليها الحراشف ثم العيون. بينت نتائج الزرع الجرثومي وجود ميكروبات موجبة الغرام منها Staphylococcus aureus, و ميكروبات سالبة الغرام هي: Escherichia coli , Proteus sp. , Salmonella spp. , Shigella sp. , Pseudomonas spp. و كانت مرحلة وصول الأسماك إلى المسمكة هي الأكثر تلوثاً بهذه الميكروبات.
The aim of this study was to evaluate the effect of handling on the quality and safety of Sea Bass, Dicentrarchus labrax. The samples were collected from the marine waters of Tartous, and were traced from catch till arrival to consumers. Sensorial and microbial examinations during fish handling were done, and some physical and chemical characteristics of waters in the fishing area were determined. The results showed that the sensorial characteristics differed during fish handling and started to decrease in the marketplace. The results also showed that the number of microorganisms increased during fish handling and reached the highest level in the marketplace. This increase was observed particularly in summer. The gills were the most infected part by handling followed by the scales and then the eyes. The microbial results also showed the presence of gram positive bacteria such as Staphylococcus Aureus, and gram negative bacteria such as Escherichia coli, Proteus sp., Salmonella spp., Shigella sp., Pseudomonas spp.. The market was the most infecting with these microbes.

The main objective of this study was to determine the level of consumer
awareness toward food safety in Damascus, the biggest governorate in Syria.
The data were obtained from a survey of 196 consumers in Damascus, during
the year 2012. A special

index matching levels of each influent factor, and the study revealed that there
were significant differences among index means for categories of: age, gender,
education, marital status, income, sector of work, place of living and place of
shopping. According to the Probit model analysis, older persons had higher
probability of having awareness toward food safety by 18.8% and 16.8% for
the second and third (older) category of age. Women were more aware than
men by 9.2%. High education increases the probability. Likewise, The average
level of income had the highest probability of having awareness by about 34.9%
comparing with low and high income groups. The study recommended to create
a special informative campaigns targeting especially groups with low levels of
awareness, throughout the most favorite ways for consumers, which were T.V.
