A farm‐to‐consumption quantitative microbiological risk assessment (QMRA) for Salmonella in pigs the European Union has been developed Food Safety Authority. The primary aim of QMRA was to assess impact hypothetical reductions slaughter‐pig prevalence and control measures on human infection. key consideration during development characterization variability between E.U. Member States (MSs), therefore a generic MS model that accounts differences pig production, slaughterhouse practices,...
Graphical perception studies have largely focused on how accurate participants can be at extracting quantitative information from glyphs in various visualization types, including infographics. However, most assume that there is only one correct way to encode information, for example compare two circles the encoding mechanism must relative area. We suspect this assumption over-simplistic, especially an obvious two- dimensional structure, and some use height instead. This a crucial, but it...
As part of the evidence base for development national control plans Salmonella spp. in pigs E.U. Member States, a quantitative microbiological risk assessment was funded to support scientific opinion required by EC from European Food Safety Authority. The main aim assess effectiveness interventions implemented on‐farm and at abattoir reducing human cases pig meat–borne salmonellosis, how effects these may vary across States. Two case study States have been chosen effect investigated....
Previous modelling studies have estimated that between 1% and 10% of human salmonella infections are attributable to pig meat consumption. In response this food safety threat the British industry initiated a monitoring programme. It is anticipated programme will contribute achieving UK Food Standards Agency target for reducing levels in pigs at slaughter by 50% within 5 years. order better inform programme, we developed stochastic transmission model specialist grower-finisher herd, where...
The burden of Salmonella entering pig slaughterhouses across the European Union is considered a primary food safety concern. To assist E.U. member states with development national control plans, we have developed farm transmission model applicable to all states. It an individual‐based stochastic susceptible‐infected that takes into account four different sources infection pigs (sows, feed, external contaminants such as rodents, and new stock) various management practices linked...
A model for the transmission of Salmonella between finisher pigs during transport to abattoir and subsequent lairage has been developed, including novel factors such as environmental contamination effect stress, is designed be adaptable any EU Member State (MS). The forms part a generic farm-to-consumption in pigs, potentially important risk assess effectiveness interventions. In this article, we discuss parameterization two case study MSs. For both MSs, predicted an increase average...
In response to the European Food Safety Authority's wish assess reduction of human cases salmonellosis by implementing control measures at different points in farm‐to‐consumption chain for pork products, a quantitative microbiological risk assessment (QMRA) was developed. The model simulated occurrence Salmonella from farm consumption cuts, minced meat, and fermented ready‐to‐eat sausage, respectively, dose‐response used estimate probability illness consumption. QMRA has generic structure...
Abstract The transmission of pathogens across the interface between wildlife and livestock presents a challenge to development effective surveillance control measures. Wild birds, especially waterbirds such as Anseriformes Charadriiformes are considered be natural hosts Avian Influenza (AI), presumed pose one most likely vectors for incursion AI into European poultry flocks. We have developed generic quantitative risk map, derived from classical epidemiological equation, describe relative,...
Many data visualization experts recommend the use of bar charts over pie because they consider comparing area or angle segments to be less accurate than bars on a chart. However, many studies show that when chart is used estimate proportions (arguably its main function) it as A major issue most previous have only looked at one method extracting information from charts, for example either by segment circle (the part-whole relationship) another (relative magnitude estimation). Therefore, in...
Foodborne infection is a result of exposure to complex, dynamic food systems. The efficiency foodborne driven by ongoing shifts in genetic machinery. Next-generation sequencing technologies can provide high-fidelity data about the genetics pathogen. However, safety surveillance systems do not currently similar epidemiological metadata associate with data. As consequence, it rarely possible transform into actionable knowledge that be used genuinely inform risk assessment or prevent outbreaks....
The scientific understanding of the driving factors behind zoonotic and pandemic influenzas is hampered by complex interactions between viruses, animal hosts humans. This complexity makes identifying influenza viruses high or risk, before they emerge from populations, extremely difficult uncertain. As a first step towards assessing risk influenza, we demonstrate assessment framework to assess relative likelihood A circulating in making species jump into intention that such could assist...
Aerial photography from the 1940s through 1950s of Wisconsinan and Holocene portion lower Mississippi alluvial valley 32°N to 34.6°N identifies three previously unrecognized areas that have circular elliptical tonal anomalies similar in size, shape, spacing aerial signature sand blows documented this region by trenching. Coring, ground conductivity surveying, trenching, sedimentological/soil analysis, age analysis 14C luminescence techniques demonstrate these are fields seismically induced...

Summary Cryptosporidiosis caused by Cryptosporidium parvum infection is a major cause of enteric illness in man and there significant reservoir animals, particularly young ruminant species. To preliminary assess the magnitude risk posed contact with faeces produced infected livestock, two microbiological assessments have been developed: one for human C. while camping on contaminated land recently grazed suckler cattle comparable assessment spread slurry. Using worst‐case scenario approach,...
