Eastern Equine Encephalitis Virus: A Scoping Review of the Global Evidence.

Eastern equine encephalitis virus (EEEV) is a mosquito-borne virus that is primarily found in North America and the Caribbean. Over the past decade there has been an increase in virus activity, including large outbreaks in human and horse populations. Predicted climate change is expected to affect the range of mosquitoes including vectors of EEEV, which may alter disease risk posing a public health concern.

A systematic review and meta-analysis of predictors of human hepatitis E virus exposure in non-endemic countries.

The reported incidence of clinical hepatitis E cases is rising in some non-endemic countries, with concurrent concerns regarding potential hepatitis E virus (HEV) contamination of the blood supply. Therefore, the characterization of major potential sources of human HEV exposure is important to inform risk assessment and public health policy. A systematic review was conducted, including a comprehensive search in six electronic bibliographic databases, verified by hand-searching reference lists of HEV reviews, and a grey literature search, of the broad research question 'what is the evidence of the association between predictors of human HEV exposure, and HEV IgG seropositivity, in non-endemic countries?' Using forms designed a priori, captured studies were appraised at first-level screening, second-level characterization, and third-level data extraction and risk of bias assessment.

A systematic review and meta-regression of single group, pre-post studies evaluating food safety education and training interventions for food handlers.

Background: Food handlers working in retail and food service establishments are a frequent source of foodborne disease outbreaks. Numerous studies have investigated different education and training approaches to improve their safe food handling knowledge, attitudes, and practices. Frequently, these studies use a single group, pre-post design, measuring changes before and after an intervention without a separate control group.

Effectiveness of Food Handler Training and Education Interventions: A Systematic Review and Meta-Analysis.

Improper food handling among those working in retail and food service settings is a frequent contributor to foodborne illness outbreaks. Food safety training and education interventions are important strategies to improve the behaviors and behavioral precursors (e.g.

Cache Valley virus: A scoping review of the global evidence.

Cache Valley virus (CVV) is a mosquito-borne RNA virus detected throughout North America, Central America and parts of South America. A limited number of human case reports have described severe illness. CVV infection has been associated with outbreaks of congenital defects in small ruminants in Canada and the United States.

Systematic review and meta-analysis of the seroprevalence of hepatitis E virus in the general population across non-endemic countries.

Background: Hepatitis E virus (HEV) has commonly been associated with large waterborne outbreaks of human jaundice in endemic areas but it has been increasingly recognised as a cause of sporadic human cases of jaundice in non-endemic areas, in individuals with no history of travel. Zoonotic exposure is widely hypothesized to be an important potential transmission route in these sporadic human cases. Serosurveys conducted to determine the frequency of HEV human exposure report wide ranges in prevalence across studies and locations.

A systematic review of individual and community mitigation measures for prevention and control of chikungunya virus.

Background: Chikungunya is a mosquito-borne virus transmitted by mosquitoes from the Aedes genus. The virus, endemic to parts of Asia and Africa, has recently undergone an emergence in other parts of the world where it was previously not found including Indian Ocean Islands, Europe, the Western Pacific and the Americas. There is no vaccine against chikungunya virus, which means that prevention and mitigation rely on personal protective measures and community level interventions including vector control.

A scoping review of published literature on chikungunya virus.

Chikungunya virus (CHIKV) has caused several major epidemics globally over the last two decades and is quickly expanding into new areas. Although this mosquito-borne disease is self-limiting and is not associated with high mortality, it can lead to severe, chronic and disabling arthritis, thereby posing a heavy burden to healthcare systems. The two main vectors for CHIKV are Aedes aegypti and Aedes albopictus (Asian tiger mosquito); however, many other mosquito species have been described as competent CHIKV vectors in scientific literature.

A systematic review on the impact of gestational Lyme disease in humans on the fetus and newborn.

Lyme disease (LD), caused by bacteria of the Borrelia burgdorferi sensu lato species complex, is the most common vector-borne disease in North America and Europe. A systematic review (SR) was conducted to summarize the global literature on adverse birth outcomes associated with gestational LD in humans. The SR followed an a priori protocol of pretested screening, risk of bias, and data extraction forms.

Psychosocial and organizational determinants of safe food handling at retail and food service establishments: a systematic review and meta-analysis.

Various psychosocial and organizational factors have been investigated as determinants of food handlers' food safety behaviours. A systematic review and meta-analysis of studies in this area was conducted to identify and synthesize the key behavioural determinants. Standard systematic review steps were followed: comprehensive search strategy; relevance screening; article characterization; risk of bias assessment; data extraction; and random-effects meta-analysis.

Powassan virus, a scoping review of the global evidence.

Background: Powassan virus (POWV), a flavivirus discovered in 1958, causes sporadic but severe cases of encephalitis in humans. Since 2007, the number of human Powassan cases diagnosed each year in the USA has steadily increased. This is in agreement with predictions that Powassan cases may increase in North America as a result of increased exposure to infected ticks.

Explaining the food safety behaviours of food handlers using theories of behaviour change: a systematic review.

Theories of behaviour change can explain the factors affecting food handlers' use of food safety practices. A systematic review was conducted on this topic to identify which theories have been applied in this area and to determine which theories are the most consistent predictors of food handlers' behaviours. Standard systematic review procedures were followed: comprehensive search strategy; relevance screening of abstracts; article characterization; data extraction; risk-of-bias assessment; and descriptive analysis.

Food Safety at Farmers' Markets: A Knowledge Synthesis of Published Research.

Farmers' markets are increasingly popular venues in North America for the sale of fresh produce and other foods. However, the nature of their operation can present possible food safety issues, challenges, and risks to consumers. A knowledge synthesis was conducted to identify, characterize, and summarize published research on the microbial food safety issues and implications associated with farmers' markets.

Risk perceptions, attitudes, and knowledge of chikungunya among the public and health professionals: a systematic review.

Background: Recently, attention to chikungunya has increased due to its spread into previously non-endemic areas. Since there is no available treatment or vaccine, most intervention strategies focus on mosquito bite prevention and mosquito control, which require community involvement to be successful. Thus, our objective was to systematically review the global primary literature on the risk perceptions, attitudes, and knowledge of chikungunya among the public and health professionals to inform future research and improve our understanding on which intervention strategies are likely to be successful.

Explaining Consumer Safe Food Handling Through Behavior-Change Theories: A Systematic Review.

Consumers often engage in unsafe food handling behaviors at home. Previous studies have investigated the ability of behavior-change theories to explain and predict these behaviors. The purpose of this review was to determine which theories are most consistently associated with consumers' safe food handling behaviors across the published literature.

The Accuracy of Diagnostic Tests for Lyme Disease in Humans, A Systematic Review and Meta-Analysis of North American Research.

There has been an increasing incidence of Lyme disease (LD) in Canada and the United States corresponding to the expanding range of the Ixodes tick vector and Lyme disease agent (Borrelia burgdorferi sensu stricto). There are many diagnostic tests for LD available in North America, all of which have some performance issues, and physicians are concerned about the appropriate use and interpretation of these tests. The objective of this systematic review is to summarize the North American evidence on the accuracy of diagnostic tests and test regimes at various stages of LD.

Scoping Review of the Zika Virus Literature.

The global primary literature on Zika virus (ZIKV) (n = 233 studies and reports, up to March 1, 2016) has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations) 56.

A systematic review and meta-analysis of the effectiveness of food safety education interventions for consumers in developed countries.

Background: Foodborne illness has a large public health and economic burden worldwide, and many cases are associated with food handled and prepared at home. Educational interventions are necessary to improve consumer food safety practices and reduce the associated burden of foodborne illness.

Methods: We conducted a systematic review and targeted meta-analyses to investigate the effectiveness of food safety education interventions for consumers.

Scoping Review of Research on the Effectiveness of Food-Safety Education Interventions Directed at Consumers.

Improper food handling by consumers at home is a major cause of foodborne illness. Therefore, effective education strategies are essential to change consumers' food safety attitudes and behaviors. The purpose of this scoping review was to identify and characterize primary literature examining the effectiveness of consumer food-safety education interventions.

A scoping review of scoping reviews: advancing the approach and enhancing the consistency.

Background: The scoping review has become an increasingly popular approach for synthesizing research evidence. It is a relatively new approach for which a universal study definition or definitive procedure has not been established. The purpose of this scoping review was to provide an overview of scoping reviews in the literature.

A scoping review of the evidence for public health risks of three emerging potentially zoonotic viruses: hepatitis E virus, norovirus, and rotavirus.

Emerging zoonoses are defined as those newly recognized, or increasing in incidence or geographic range. Hepatitis E virus (HEV), norovirus (NoV), and rotavirus (RV), while well known to be transmitted person-person, have also been hypothesized to be emerging zoonoses. Our objective was to investigate their potential public health risks from animal reservoirs.

A guide for developing plain-language and contextual summaries of systematic reviews in agri-food public health.

The application of systematic reviews is increasing in the agri-food public health sector to investigate the efficacy of policy-relevant interventions. In order to enhance the uptake and utility of these reviews for decision-making, there is a need to develop summary formats that are written in plain language and incorporate supporting contextual information. The objectives of this study were (1) to develop a guideline for summarizing systematic reviews in one- and three-page formats, and (2) to apply the guideline on two published systematic reviews that investigated the efficacy of vaccination and targeted feed and water additives to reduce Salmonella colonization in broiler chickens.

Prevalence of zoonotic bacteria in wild and farmed aquatic species and seafood: a scoping study, systematic review, and meta-analysis of published research.

Increased reliance on seafood has brought to light concerns regarding food safety, but the information to inform risk assessment or surveillance needs is lacking. A scoping study (ScS) was conducted to characterize published research investigating selected zoonotic bacteria and public health topics in various wild and farmed aquatic species and seafood. This was followed by a systematic review (SR) on selected bacteria (Aeromonas spp.

The effect of hazard analysis critical control point programs on microbial contamination of carcasses in abattoirs: a systematic review of published data.

Hazard analysis critical control point (HACCP) programs have been endorsed and implemented globally to enhance food safety. Our objective was to identify, assess, and summarize or synthesize the published research investigating the effect of HACCP programs on microbial prevalence and concentration on food animal carcasses in abattoirs through primary processing. The results of microbial testing pre- and post-HACCP implementation were reported in only 19 studies, mostly investigating beef (n=13 studies) and pork (n=8 studies) carcasses.
