This study was conducted to determine the effectiveness of electrical conductivity (EC) method on diagnosis subclinical mastitis in dairy cows comparing with somatic cell count (SCC) and California test (CMT), also investigate effect these values amount total viable bacteria, density, freezing point, mineral substances. A 386 milk samples collected from quarters 188 at 10 different farms were used as materials. Of samples, 258 (66.85%) CMT (+), 85 (22.02%) (++), 43 (11.13%) (+++). The mean...
The aim of this study was to determine the mold and ochratoxin A (OTA) contamination tarhana, a traditional product widely consumed in Turkish cuisine. For purpose, total 350 tarhana samples (homemade industrially produced) were randomly collected from retail stores, markets, bazaars different regions Türkiye analyzed by means LC-MS/MS for occurrence OTA. According results, OTA detected 36 150 (24%) produced samples, with concentration range 0.12–2.34 µg/kg, while 118 200 (59%) homemade...
This study evaluated heavy metal levels (Pb, Cd, Hg, As, Cu) and the presence of Salmonella spp. Listeria monocytogenes in mussels commonly consumed fishery products from Marmara region Türkiye. Health risks were using total hazard quotient (THQ) index (HI) values, while microbial fresh ready-to-eat (RTE) estimated via Risk Ranger tool. Among 625 samples, Hg (36.96%; CI95 = 33.27–48.81), Pb (9.76%; 7.67–12.34), Cd (19.36%; 16.45–22.64) exceeded permissible limits, except crabs, which...
The effect of rosemary (Rosmarinus officinalis L.) essential oil (REO) and modified-atmosphere packaging (MAP) on the survival certain pathogens (Salmonella Typhimurium Listeria monocytogenes) in poultry fillets their meat quality during 7 days refrigerated storage were investigated. Because REO at 0.05% 0.1% had weak antibacterial activity 0.3%, 0.5% 1.0% imparted unacceptable organoleptic properties, only 0.2% was used to treat meat. results showed that adding did not reduce size...
Effect of various voltage electrical stimulation (ES) on meat quality lamb and goat was investigated by using a total 36 animals at 3-5 years old. Constant 50 Hz frequency 50, 100, 250 V, 90 sec ES were administered to 1/2 carcasses examined according their textural, physicochemical, sensorial characteristics. decreased the pH values meat, accelerated rigor mortis (P < 0.05). Additionally, enhanced water activity, water-holding capacity, drip loss both animals. Shear force varied between...
ABSTRACT Tekirdağ köfte, a Turkish‐style meatball, is one of the most popular ground meat products in Turkey. The aim this study was to evaluate effect different nisin and lactoferrin (Lf) concentrations their combinations on microbiological quality meatball (Tekirdağ köfte). For purpose, dough divided into six equal groups, each groups treated separately with and/or Lf (0, 100 200 µg/g). Analyses were performed group at 0, 1, 3, 5, 7, 10 12 days for parameters (total mesophilic aerobic...
The ice used in the food industry has to be safe and water production should have quality of drinking water. consumption contaminated directly or indirectly may a vehicle for transmission pathogenic bacteria humans producing outbreaks gastrointestinal diseases. objective this study was monitor microbiological ice, hygienic conditions making machines various enterprises. Escherichia coli detected seven (6.7%) 23 (21.9%) chest samples whereas E. negative all examined samples. Psychrophilic...
Clostridioides (Clostridium) difficile is a Gram (+), anaerobic, spore forming, rod shaped bacterium that can produce toxin. The objective of this study to reveal the presence C. in meat products, analyze ribotype diversity by PCR and evaluate antibiotic susceptibility isolated strains. organism was 22 out 319 (6.9%) examined product samples 9 (40.9%) isolates were identified as RT027 all had ability toxin production. In terms susceptibility, susceptive amoxicillin-clavulanic acid,...
Tarhana is a popular traditional Turkish cereal-based fermented food product mainly produced at home or home-scale level. Some certain mould species can grow even low moisture and pH values produce aflatoxins in food. This study was conducted to determine aflatoksin levels tarhana. For this purpose, total of 138 tarhana powder samples were collected from bazaars Istanbul analyzed for aflatoxins, contamination, some physico-chemical parameters. As result, 32 out (23.2%) found be contaminated...
Purpose This study was performed to determine the microbial quality of stuffed mussels and discuss microbiological criteria ready‐to‐eat (RTE) foods defined in Turkish Food Codex (TFC). Design/methodology/approach Stuffed mussel (Midye Dolma), which can be classified as RTE foods, made from rice, cooked separately then put together shell, is commonly consumed Turkey. special food might an important source microorganisms especially pathogen bacteria because preparation serving process. During...
This study was conducted to investigate the effects of chitosan treatment on quality criteri as shrimps for a long time "in chilled" storage.Fresh deepwater pink (Parapenaeus longirostris), caught from Marmara Sea were dipped in different solutions containing combinations sodium metabisulphite (2500 mg/L), 4-hexylresorcinol (50 (5 g/L), citric acid (200 mg/L) and rosemary extract ten minute, over-wrapped styrofoam plates stored at 4°C six days.During storage period, pH, microbiological...
Ochratoxin A, is a well-known nephrotoxic, hepatotoxic and carcinogenic mycotoxin, produced by some species of mould genera such as Aspergillus spp. Penicillium under various environmental conditions, moisture temperature. The main sources A intake for humans are cereals cereal derived products, when they consumed in large quantities, the case breakfast based baby foods principally babies. In this study, total 150 samples (50 infant formulas, 50 follow-on supplementary infants children) were...
Purpose The purpose of this study is to investigate the effect lemon juice on survival Salmonella Enteritidis and Escherichia coli in cig kofte (raw meatball). Design/methodology/approach Cig samples were inoculated one by with both bacteria at high inoculum levels treated different doses fresh (2, 5, 10 15 ml) for seconds, 30 1, 15, 60 minutes. Findings Treatments exposure times caused reduction ranging between 0.1 1.7 log CFU/g 2.1 E.coli . Results showed that slight decrease as an...
Mastitis is recognized as one of the most important diseases affecting dairy industry. The antibiotic susceptibility test to achieve accurate treatment in subclinical mastitis. This study was conducted determine presence contagious mastitis agents (Streptococcus agalactiae and Staphylococcus aureus) 270 bovine milk samples collected from 132 cows with 15 different farms located Marmara Region Turkey. A total 256 bacterial pathogens were isolated, which 25 isolates identified S. 12 aureus....
