A minimum data set consisting of 15 data elements originating from laboratory submissions and results was formulated by a national committee of epidemiologists in Canada for the purposes of disease reporting, disease detection and analysis. The data set consists of both data that are filled out on the submission form as well as the results of the laboratory testing. The elements in the data set are unique identifier, premises identification, date submitted, geographic location, species, farm type, group type, total population of tested species on the farm, number sick, number dead, test(s) performed, disease agent, test result, disease classification by submitter and final laboratory diagnosis. The data set was designed to be concise while allowing for domestic and international disease reporting, effective analysis, including geographic, temporal and prevalence outputs, and syndromic surveillance to enable disease detection. The selected data elements do not identify the producer as specific geographic and nominal information is not included in the data set. The data elements selected, thus, allow for voluntary collaboration and data sharing by avoiding issues associated with privacy legislation. © 2011 Her Majesty the Queen in Right of Canada.

Food Protection Trends | Year: 2014
Parasitic diseases are of considerable public health significance in Canada, particularly in rural and remote areas. Food- and water-borne parasites contribute significantly to the overall number of parasitic infections reported in Canada. While data on the incidence of some of these diseases are available, knowledge of the true burden of infection by the causative agents in Canadians is somewhat limited. A number of centers of expertise in Canada study various aspects of parasitology, but few formal societies or networks of parasitologists currently exist in Canada, and previously none focused specifically on food or environmental transmission. The recently established Food and Environmental Parasitology Network (FEPN) brings together Canadian researchers, regulators and public health officials with an active involvement in issues related to these increasingly important fields. The major objectives of the Network include identifying research gaps, facilitating discussion and collaborative research, developing standardized methods, generating data for risk assessments, policies, and guidelines, and providing expert advice and testing in support of outbreak investigations and surveillance studies. Issues considered by the FEPN include contaminated foods and infected food animals, potable and non-potable water, Northern and Aboriginal issues, zoonotic transmission, and epidemiology.

Integrated surveillance of pathogens along the food chain and the multidisciplinary investigation of food hazards are considered international best practices. Integrated surveillance of Salmonella was initiated in British Columbia (BC), Canada in 2006. The objectives of this paper were 1) to describe the BC integrated surveillance experience, 2) to present findings from the integrated surveillance of Salmonella, and 3) to identify the components that enabled the program. Data about BC animal, food and human Salmonella isolates from 2006 to 2010 (n= 5003) were centrally collated and analysed. Among chickens, chicken meat and humans, the most common serotypes identified were S. Enteritidis, S. Typhimurium and S. Heidelberg. An increase in S. Enteritidis in all three sectors in 2007-9 led to a multi-disciplinary and multi-sectoral investigation. An evaluation of the integrated surveillance program helped identify four critical program elements: dedicated people, cross-sectoral sharing and integration of data, multi-disciplinary analysis and interpretation of findings, and collaborative multi-sectoral response. Ongoing challenges include lack of resources and infrastructure to sustain the program. © 2011 Elsevier Ltd.

Diseases of Aquatic Organisms | Year: 2013
Post-mortem examination of dead and live stranded beach-cast pinnipeds and cetaceans for determination of a cause of death provides valuable information for the management, mitigation and prosecution of unintentional and sometimes malicious human impacts, such as vessel collision, fishing gear entanglement and gunshot. Delayed discovery, inaccessibility, logistics, human safety concerns, and weather make these events challenging. Over the past 3 decades, in response to public concern and federal and state or provincial regulations mandating such investigations to inform mitigation efforts, there has been an increasing effort to objectively and systematically investigate these strandings from a diagnostic and forensic perspective. This Theme Section provides basic investigative methods, and case definitions for each of the more commonly recognized case presentations of human interactions in pinnipeds and cetaceans. Wild animals are often adversely affected by factors such as parasitism, anthropogenic contaminants, biotoxins, subclinical microbial infections and competing habitat uses, such as prey depletion and elevated background and episodic noise. Understanding the potential contribution of these subclinical factors in predisposing or contributing to a particular case of trauma of human origin is hampered, especially where putrefaction is significant and resources as well as expertise are limited. These case criteria descriptions attempt to acknowledge those confounding factors to enable an appreciation of the significance of the observed human-derived trauma in that broader context where possible. © Inter-Research 2013.

Rangelands | Year: 2011
Fur, gold, and settlement are the building blocks of rangefield management in British Columbia. Furs were integral to development of trade and transportation corridors in British Columbia. Furs had high value, and early explorers representing fur-trade companies trekked across the seemingly limitless spaces and wilderness to facilitate trade with First Nations peoples. The Hudson's Bay Company used an extensive system of boats and horse trails to carry furs from central British Columbia to the mouth of the Columbia River. The rugged Coast Mountains presented an awe-inspiring barrier to travel. The Fraser River cut through the mountains, but it was too swift and treacherous for boat travel. Attitudes in the early twentieth century contributed to a lack of concern for range condition. The provincial government believed there were great opportunities for increasing the cattle industry by utilizing unused range on the vast natural stock ranges.

Epidemiology and Infection | Year: 2016
The objective of this study was to assess the use of statistical algorithms in identifying significant clusters of Salmonella spp. across different sectors of the food chain within an integrated surveillance programme. Three years of weekly Salmonella serotype data from farm animals, meat, and humans were used to create baseline models (first two years) and identify weeks with counts higher than expected using surveillance algorithms in the third (test) year. During the test year, an expert working group identified events of interest reviewing descriptive analyses of same data. The algorithms did not identify Salmonella events presenting as gradual increases or seasonal patterns as identified by the working group. However, the algorithms did identify clusters for further investigation, suggesting they could be a valuable complementary tool within an integrated surveillance system. © Copyright.

Zoonoses and Public Health | Year: 2012
An increase in the rate of human infections with Salmonella enteritidis (SE) occurred between 2007 and 2010 in British Columbia (BC). During the same time period, an increase in SE from poultry-sourced isolates and increased clinical severity in poultry were also observed in BC. This article describes a multi-sectoral collaboration during a 3-year investigation, and the actions taken by public health and animal health professionals. Human cases were interviewed, clusters were investigated, and a case-control study was conducted. Environmental investigations were conducted in food service establishments (FSE). Suspect foods were tested. Laboratory data from poultry-sourced isolates were analysed. Five hundred and eighty-four human cases of SE with the same pulsed-field gel electrophoresis pattern were identified between May 2008 and August 2010. Seventy-three percentage of cases reported consumption of eggs. The odds of egg consumption were 2.4 times higher for cases than controls. Implicated FSE were found to use ungraded eggs, which had been distributed illegally. Investigation suggested that there were multiple suppliers of these eggs. Collaboration between public health and animal health professionals led to data sharing, improved understanding of SE, engagement with the poultry industry and public communication. Multi-disciplinary, multi-sectoral and multi-pronged investigations are recommended to identify the likely source of illness in large, protracted foodborne outbreaks caused by commonly consumed foods. © 2012 Blackwell Verlag GmbH.
