The bovine spongiform encephalopathy (BSE) crisis in Member States of the European Union adversely affected beef consumption in Slovenia in 1996. Although the disease has not been reported in Slovenia to date, the controversy about the link between BSE and Creutzfeldt-Jakob disease and scandals related to the illegal trade in beef in some countries have triggered doubts among consumers. Beef co...

  Escherichia coli O157:H7 is an important human pathogen causing haemorrhagic colitis, haemolyticuraemic syndrom and thrombotic thrombocytopenic purpura. In this study, 100 ground beef samples were collected randomly from beef markets in June 2004. For isolation of the bacteria, samples were firstly enriched in modified trypticase soy broth, followed by plating onto sorbitol MacConkey agar sup...

BACKGROUND A Step I diet with lean beef compared with lean white meat both decrease LDL cholesterol. To our knowledge, no studies have evaluated a low-saturated fatty acid (SFA) (<7% calories) diet that contains lean beef. OBJECTIVE We studied the effect on LDL cholesterol of cholesterol-lowering diets with varying amounts of lean beef [ie, Dietary Approaches to Stop Hypertension (DASH): 28 g...

or identical, twin beef animals in growth and nutrition studies. The problem of continuous versus discontinuous growth of beef cattle in relation to the economics of beef production is under investigation at the U. S. Animal Husbandry Experiment Station at Beltsville, Maryland, and data now being obtained with identical twins should lead eventually to the production of more pounds of beef per 1...

abstract in agriculture, there is a lag between planting decision and supplying the produced commodity to the market. this makes the marketed commodities as predetermined variables and prices as market clearing factor. under such a condition, the inverse demand function in which price is a function of quantity is an appropriate tool for forecasting price responses to the injected quantities to ...

The USMARC beef carcass image analysis system objectively evaluates beef carcass grade factors including marbling score, adjusted preliminary yield grade, and ribeye area (Figure 1). This image analysis system can assess USDA yield grade more precisely and accurately than can be achieved by USDA graders. Furthermore, use of this image analysis system will allow for creation of additional yield ...

Eating in table-service restaurants has been implicated as a risk factor for Escherichia coli O157:H7 infection. To explore this association and learn about the prevalence of risky ground beef preparation practices in restaurants, the Environmental Health Specialists Network (EHS-Net) assessed ground beef handling policies and practices in restaurants in California, Colorado, Connecticut, Georg...

Previous research demonstrated significant variation in the prevalence of Salmonella in peripheral lymph nodes (LNs) of feedlot cattle and cull cows, with greater prevalence in feedlot cattle. Therefore, we performed experiments to investigate whether these differences in Salmonella prevalence in subiliac LNs are due to, or influenced by, breed, which in many respects is a proxy for the product...

Blomeke, C.R., Rusk, C.P., Balschweid, M.A., & Elliott, S.J. The purpose of this study was to evaluate retinal imaging technology as a means of permanent identification of 4-H beef and sheep projects. The specific objectives of this study were to compare the time required to collect a retinal image versus a nose print, and to determine the false match and false non-match rate of visual verifica...

In order to allow consumers to trace to the whole process of beef breeding, production and processing after purchasing beef, to achieve smart, fast and practical goals for quality and safety of beef traceability system, B / S (Browser / Server) mode architecture is used to build quality beef traceability system based on RFID technology in this paper. First, the system is analyzed, the structure...
