The aim of this study was to investigate the incidence of Arcobacter species in water sources and raw milk from healthy animals in Kayseri, Turkey. A total of 175 samples of drinking water (n = 100), spring water (n = 25), and raw milk (n = 50) were examined. Arcobacter species were isolated using the membrane filtration technique. Overall, 7 (4%) of the 175 samples yielded Arcobacter spp.: 3 (3%) drinking water samples, 1 (4%) spring water sample, and 3 (6%) raw milk samples. Two species of Arcobacter were recovered from the seven positive samples: Arcobacter butzleri, Arcobacter skirrowii, and A. butzleri plus A. skirrowii found in 3 (1.7%), 2 (1.1%), and 2 (1.1%) samples, respectively. Our study is the first to report the isolation of both A. butzleri and A. skirrowii together from drinking water and is the first report of Arcobacter in milk from healthy cows in Turkey. Based on these findings, the presence of Arcobacter species in environmental waters and raw milk may pose a potential hazard for human health.

Cd, Ni, Cr, Zn, Cu and Pb concentrations of muscle tissue of 61 fish samples belonging to six fish species (Sparus auratus, Pomatomus saltatrix, Sarda sarda, Engraulis encrasicholus, Sander lucioperca, Scomber scombrus) retailed in Kayseri, Turkey were determined by flame atomic absorption spectrometry after wet digestion. Cd concentrations of at least 31 fish samples (50.8%) and Pb concentrations of at least six fish samples (9.8%) exceeded the corresponding Turkish permissible limit of 0.05 and 0.2 mg kg(-1) respectively whereas Zn concentrations of 11 fish samples (18%) exceeded the Turkish Food Codex limits of 50 mg kg(-1) for Zn. Cu concentrations of all fish species analyzed (100%) were below the corresponding Turkish legislations of 20 mg kg(-1). No limits were established concerning Ni and Cr concentrations in fish by the Turkish governmental authorities.
