Staphylococcus aureus, a major food-poisoning pathogen, is a common contaminant in dairy industries worldwide, including in Brazil. We determined the occurrence of S. aureus in five dairies in Brazil over 8 months. Of 421 samples, 31 (7.4%) were positive for S. aureus and prevalence varied from 0 to 63.3% between dairies. Sixty-six isolates from the 31 samples were typed by Multi-Locus Sequence...

This study analyzes the impacts of reducing greenhouse gas (GHG) emissions on meat and dairy industries. To achieve this goal, Global Trade Analysis Project (GTAP) database was used in a Computable General Equilibrium (CGE) setting, which allows for inclusion carbon taxes definition four alternative environmental policies scenarios using both Warming Potential (GWP) Temperature (GTP) as GHG mea...

this survey aimed to evaluate the level of lead (pb) pollution in cattle in the vicinity of the shiraz oil and petrochemical industries using hair samples. dairy farms located within 10 km of the shiraz oil and petrochemical industries were identified and divided into four groups. farms that were located in the radial zones of 0.5-1.5 km, 1.5-5 km, 5-7 km, 7-10.5 km were considered as groups a,...

Expert systems (ES) development technology has been used to build rural business applications in the past but these have usually been developed using traditional expert systems shells. This paper introduces a new architecture for the development of a design environment where the domain experts can build a knowledge base for target-specific ES for rural business operators. The system allows rura...
