BACKGROUND School visits to farms are a positive educational experience but pose risks due to the spread of zoonotic infections. A lesson plan to raise awareness about microbes on the farm and preventative behaviours was developed in response to the Griffin Investigation into the E. coli outbreak associated with Godstone Farm in 2009. This study evaluated the effectiveness of the delivery of th...

Little information currently exists regarding the risk of low-back disorders among youth who perform physically demanding farm activities. Thus, afield study was conducted in which children and adolescents who engage in farm work were recruited, fitted with a lumbar motion monitoring system, and then observed performing their usual chores. The lumbar motion monitor was used to record the trunk ...

The study objective was to evaluate three methods of Salmonella enterica prevalence estimation in swine herds (faecal culture, culture of abattoir-collected samples, and serum ELISA). From each of six swine herds, we necropsied approximately 100 finishing pigs (> 70 kg); one-half on farm and the other half at the abattoir, after transport and approximately 2.5 h holding. We collected the same s...

BACKGROUND Heavy carrying and lifting (HCL) is a common activity among farmers that may be related to health. The aim of this study was to examine HCL as a proxy for occupational physical activity (PA) among farm residents. The secondary objective was to evaluate PA based on HCL. METHODS Data from 21,296 farmers and 30,951 spouses in the Agricultural Health Study examined the relationship bet...

OBJECTIVES We unexpectedly identified MRSA isolates carrying mecC (mecC-MRSA) from a Danish swine farm located in eastern Zealand. The objective of the present study was to investigate the origin of these isolates and their genetic relatedness to other mecC-MRSA isolates from Zealand. METHODS WGS was used to infer the phylogenetic relationship between 19 identified mecC-MRSA isolates from the...

In Year 1, there are only ten factories, which can employ a maximum of 100 workers. Hence most farms will still have all five siblings working there. The total farm income will be $100, so the average product of labor is $20 = 100 5 . The marginal product is 0, since when there are at least three siblings working on the farm, any additional worker does not increase farm income. Consequently two...

Many Michigan farm children are viewed as having suffered a deterioration in health coincident with contamination of dairy cattle by PBBs. Among Wisconsin dairy farm children such a deterioration was a rare event. There is a suggestion that Michigan farm children who had multiple symptoms during the 1973-76 period are getting better. A discrete syndrome of ill health has not been identified amo...

Farm management focused on maximizing biomass production results in biological simplification and ultimately a degraded production potential for the future. Despite the large and growing body of evidence pointing to the need to restore biodiversity to farm systems, incorporation of biodiversity and ecosystem services into local agricultural land use decision-making remains limited. The lack of ...

Many U.S. states imposed temporary moratoria on farm and nonfarm residential mortgage foreclosures during the Great Depression. This article describes the conditions that led some states to impose these moratoria and other mortgage relief during the Depression and discusses the economic effects. Moratoria were more common in states with large farm populations (as a percentage of total state pop...

This paper addresses the development of farm businesses in Sweden, 2000–2007, with regard to their specialization in single farm enterprises, diversified agricultural production and diversification with new income-generating ventures. Furthermore, regression analysis is used to study the impact of farm characteristics on the observed specialization and diversification. The study is based a pane...
