    ABSTRACT: Objective: To determine the microbiological quality of home meals and salads samples. Methodology: A total of 180 samples were collected between May 2007 and July 2007 in Ankara, Turkey. The samples were analysed for the presence of total aerobic bacteria (TAB), thermotolerant coliform bacteria (TCB), Esherichia coli, Salmonella spp. and Staphylococcus aureus. Results: In the present study, S.aureus, coliforms, E.coli, and Salmonella were not detected in cooked meat meals samples. TAB was detected in 22 (24.4%) meat dishes ranges 10 2 -10 4 . The cooked meat dishes samples were analyzed for the presence of TCB, and detected in 2 (2.2%) meat dishes ranges 10 3 -10 4 . Numbers of the aerobic mesophilic bacteria ranged from 10 2 to 10 5 cfu/g and coliforms from 37 to 1400 MPN/g in 17 (18.9%) of salad samples. E.coli was detected at level 10 2 -10 3 (n=12, 13.3%) and S. aureus was detected in 9 (10.0%) at levels of 10 3 -10 4 cfu/ g salad samples tested. In 4 (4.4%) of the salads samples S.aureus and E.coli were isolated together. Conclusion: The results indicate that the type of vegetable salads analysed may contain pathogenic bacteria and thereby represent a risk to the consumers in regard to foodborne diseases. Thus, it remains essential to include the significance of effective hygiene practices as an important safety measure in programmes of home hygiene, consumer education, and advice quality of home cooked meat meals and vegetable salads.

    ABSTRACT: The adsorption dynamism of certain amino acids [alanine (Ala), serine (Ser), lysine (Lys), proline (Pro), and aspartic acid (Asp)] on crosslinked diethylaminoethyl (DEAE) dextran microbeads was investigated with electronic spectroscopy in aqueous solutions. Among the selected amino acids, Ala-Pro and Ser-Lys showed similar adsorption dynamism, but Asp showed the strongest tendency for adsorption. The interaction dynamism of Asp with crosslinked DEAE dextran microbeads was studied to determine the mechanism of this adsorption. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 96: 1985–1991, 2005

    ABSTRACT: The aim of this study was the analysis of mushroom poisonings (MP) in children in Central Anatolia. Cases younger than 18 y-of-age, who presented and were diagnosed as MP between January 1991 and December 2002 were evaluated for gender, age, presenting month, city of residence, first noticed symptoms, vital signs, laboratory studies, hospitalization period and outcome. Sixty-four cases were enrolled; 36 were female (56.3%). The mean age was 8.6 y. May and June were the most common presenting months, with 46 cases (71.8%); 61 cases (95.3%) were poisoned by wild mushrooms (WM). The most common first noticed symptoms were from the gastroinal system (GIS) (70.6%); 67.2% of cases presented to second level health centers when the first symptoms started; 92.2% were admitted to the hospital. Mean hospitalization period was 2.8 d. Five cases (7.8%) had a fatal outcome. All the fatal cases were from WM poisoning and from the same city. Their first noticed symptoms were GIS symptoms. All fatal cases had delayed presentations. Cultivated MP did not result in bad outcomes in the pediatric age group. WM were the main source of MP in children in our region in Turkey. Education of the public about consuming mushrooms, and health personnel working in health centers for early treatment and transfer to the appropriate facility are important to decrease mortality.

    ABSTRACT: One hundred and forty-three cases (89 women and 54 men) of mushroom poisoning recorded at the emergency service of Osmangazi University Hospital, Faculty of Medicine, between 1996 and 2000 were evaluated. The first symptoms seen were loss of consciousness, fatigue, dizziness, severe headaches, abdominal discomfort and vomiting. The symptoms characteristically appeared suddenly. Eight patients suffering from poisoning caused by cultivated mushrooms, and four patients suffering from poisoning caused by wild mushrooms died from fulminant hepatic failure. The other patients were discharged within a period of 1-10 days. It is suggested that people should be informed of the possibility of mushroom poisoning, which has been increasing recently in Turkey.
