Material and methods During 2005-2006, post slaughter examination and morphological identification of cysts from pigs from small family farms (n=612) and industrial farms (n=73) was performed. Dog fecal samples (n=240) were collected in 12 villages and microscopically examined by egg flotation/sieving (F/Si) [3] and modified McMaster methods [4]). For the genetic identification of E. granulosus...

In 1973 and 1974, several thousand Michigan dairy farms were contaminated by polybrominated biphenyls (P.B.B.) as the result of an industrial accident. An unknown quantity of contaminated meat and dairy products entered the food chain before contaminated farms were quarantined. To determine the extent of human exposure, P.B.B. concentrations were measured in human breast milk, which was collect...

This study was conducted to investigate the blood serum and diet levels of copper, zinc and iron in Holstein dairy cattle kept under industrial farming in Isfahan province, Iran. A total of 240 blood serum samples and 24 diet samples were collected from industrial dairy cattle farms. The Cu, Fe and Zn contents were assessed in samples using atomic absorption spectrophotometer. In serum samples,...

Vegetables are an inevitable and important part of a healthy and balanced diet. They could be contaminated by heavy metals in many ways including irrigation by sewage water and industrial effluents sewage sludge, vehicular emissions, industrial waste and atmospheric deposition. In this study, we sought to determine if some vegetables (cucumbers, tomatoes, cabbage, lettuce, potatoes, onions, car...

Bovine neosporosis caused by the apicomplexan protozoan parasite N. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. The aim of this study was to determine the seroprevalence of N. caninum infection in industrial dairy cattle of Hamedan province (west of Iran) by ELISA method. Blood samples were co...

BACKGROUND The main objective of this study was characterization of selected heavy metals concentrations (Lead, cadmium, copper, zinc, nickel and chromium) in groundwater used for ir-rigation in Tabriz City's countryside. METHODS After consulting with the experts of agriculture department and site survey, 38 irriga-tion water samples were taken from different farms (34 wells) without primary ...

The aim of this study was to determine the seroprevalence of avian influenzaH9N2 subtype in the industrial ostrich farms and its geographical distribution. This cross-sectional study was conducted from January to June 2015. A total of 40 farms were selected from different provinces of Iran, from each of which 11 ostriches (n=440) were sampled. The sera samples were examined using 4 hemagglutina...

abstract the industrial dairy farms in iran are facing several economic problems and about six percent of these farms were shut down in fars province due to low profitability. despite such problems and availability of other enterprises in the region, farmers do not switch to other farm activities. in this context, the factors affecting acceptance of diversification options were investigated in ...

Cystic echinococcosis is a major emerging zoonosis in many Eastern European and Asian countries. Post slaughter examinations of 684 pig livers in Lithuania revealed significantly higher numbers of Echinococcus granulosus infections in animals from family farms (13.2%; 95% CI 10.7-16.2) as compared with those from industrial farms (4.1%; 95% CI 0.8-11.5). The prevalence was also significantly hi...
