| Swine manure agricultural use is a common practice in Brazil. Their physic-chemical characteristics favor its use as biofertilizer, but the presence of pathogens may become a risk to human health. This research presents a qualitative study of the main alternatives of pig manure disinfection, analyzing efficiency, advantages and limitations of each procedure. The disinfection studies reported in literature are based on the following treatments: alkaline, thermal, biological, chemical, and physical. The greater efficiencies are in thermal treatment (> 4 log: 60 °C), chemical treatment (3 to 4 log: 30mg Cl- L-1; 3 to 4 log: 40 mg O3 L-1) and physical treatment (3 a 4 log: 220 mJ UV radiation cm-2). The biological treatment (anaerobiosis) also promotes the... |

| The shrimp farming industry in the western Indian Ocean started with Aqualma’s project in 1989, and now several companies farm shrimp in the Mozambique Channel. Despite the remoteness of these projects and their high investment and operating costs, they compete in the global marketplace by efficiently producing high value quality products. To address sustainability and biosecurity issues, Aqualma developed domesticated specific pathogenfree (SPF) broodstock of Penaeus monodon from western Indian Ocean stocks, which have been its exclusive source of post-larvae since 2003. Specific molecular diagnostic tools have been developed for each endemic pathogen detected since 1996, and these are used for routine surveillance of Aqualma’s shrimp stocks along with... |

| During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, ß-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates. Four homothallic species, P. attenuata, P. flexuosa, P. formosa and P. intricata, were isolated from rhizosphere soil of healthy forests of Fagus hayatae, Quercus glandulifera, Q. tarokoensis, Castanopsis carlesii,... |

| The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not... |

| Depuis l’assec du canal d’alimentation en 2004 après le passage du cyclone Gafilo, on a constaté une augmentation massive de la densité d’Upogebia spinimanus au sein de la ferme de l’AQUALMA-Besalampy. En cas d’apparition d’une nouvelle maladie des crustacés, ce phénomène constituerait un grand risque en favorisant sa transmission chez les crevettes élevées, voire les consommateurs. Une nouvelle méthode d’approche installée par le laboratoire centrale de l’AQUALMA s’intéresse sur la prévention des risques de maladie liée à la biosécurité, en même temps des crevettes, des consommateurs et de l’environnement. Par conséquent, durant ce 5 mois de stage, des pratiques sur terrain et en laboratoire au moyen de différentes expériences à noter le suivi... |

| Benefit cost analysis is a tried and tested analytical framework that can clearly communicate likely net changes in social welfare from investment decisions to diverse stakeholder audiences. However, in a plant biosecurity context, it is often difficult to predict policy benefits over time due to complex biophysical interaction between invasive species and their hosts. In this paper, we demonstrate how benefit cost analysis remains highly relevant to biosecurity decision-makers using the example of a plant pathogen targeted for eradication from banana growing regions of Australia, banana bunchy top virus. We develop a partial budgeting approach using a stratified diffusion spread model to simulate the likely benefits of eradication to the banana... |

| The export of grain from Western Australia depends upon a grain supply network that takes grain from farm to port through Cooperative Bulk Handling receival and storage sites. The ability of the network to deliver pest free grain to the port and onto ship depends upon the quality of grain delivered by farmers and the efficacy of phosphine based fumigation in controlling stored grain pests. Phosphine fumigation is critical to the grain supply network because it is the cheapest effective fumigant. In addition, it is also residue free. Unfortunately, over time, common stored-grain pests have evolved to develop resistance to phosphine and there is a risk that phosphine will become less effective and may need to be replaced with more expensive alternative... |

| This paper measures the cost of implementing biosecurity on broiler and layer farms in Bali. Farmer investment in biosecurity is analysed to determine if there is any difference in the implementation of biosecurity between broiler and layer farms. Data is taken from a survey of 60 layer and 60 broiler smallholder farmers in Bali in 2009. While secure boundary fencing and farm gate locks are more common on layer farms, broiler producers are more likely to have a footbaths at the shed door. In this analysis, biosecurity investments include the quality of fencing and gates, presence of locks on gates, management changes required to minimise staff and visitor movement onto and in the farm, costs of minimising vehicle entry, use of vaccination and disinfectant,... |
