Zoonosis Update Since Escherichia coli O157:H7 was first recognized in 1982 as a human pathogen, considerable progress has been made in elucidating principal vehicles of transmission. Cattle have been identified as a major source of E coli O157:H7 infection of humans, with as many as 1 in 4 animals at slaughter shedding the pathogen in feces during the summer months. 1 Case-control studies of s...

background toxoplasma gondii is a worldwide parasite which infects animals and human. infections with this zoonotic parasite are acquired mostly by consumption of undercooked or raw meat, which contains tissue cysts. objectives the current study was conducted to determine the seroprevalence of toxoplasma infection in farm animals in southern iran. materials and methods sera were obtained from 3...

The agriculture workplace has long been known to be associated with respiratory disease. Respiratory disease is among the main chronic health conditions affecting farmers (Brackbill et al, 1994). Those who are at potential risk include farmers and farm families, agricultural workers, abattoir workers, greenhouse and nursery workers, veterinarians, and grain elevator workers. While the massive e...

Confined livestock production farms typically store their wastes prior to land application. Here, we employed three complementary approaches to evaluate changes in the population structure and stability of virulence genes in Escherichia coli during manure storage on a commercial farm that housed healthy swine. Isolates were genotyped by repetitive extragenic palindromic PCR using the BOXA1R pri...

Introduction Biological soil amendments of animal origin (BSAAO), including untreated are often used to improve fertility and particularly important in organic agriculture. However, application manure on cropland can potentially introduce foodborne pathogens into the onto produce. Certified farms follow USDA National Organic Program (NOP) standards that stipulate a 90- or 120-day interval betwe...

production is hard to achieve by increasing cropping area due to limited water resources. so, increased yield per unit area may be the solution to increase production. investigating productivity of production factors is very important in this context. the objective of this study is to measure the productivity of production factors in sugar beet production in fars province. the data needed for t...

Concentrated sources of dairy manure represent significant water pollution potential. The southern United States may be more vulnerable to water quality problems than some other regions because of climate, typical farm size, and cropping practices. Dairy manure can be an effective source of plant nutrients and large quantities of nutrients can be recycled through forage production, especially w...

in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...

Mechanical separation of liquid animal manure can be an effective technique for production of a liquid and a nutrient-rich solid fraction. The efficiency of separators depends on the physical and chemical composition of the animal manure. Therefore, the particle size composition was measured for different types of manure before treatment with a decanting centrifuge and a screw press. Storage of...

This work analyzes the environmental impacts of milk production in an intensive dairy farm situated in the Northern Italy region of the Po Valley. Three manure management scenarios are compared: in Scenario 1 the animal slurry is stored in an open tank and then used as fertilizer. In scenario 2 the manure is processed in an anaerobic digestion plant and the biogas produced is combusted in an in...
