Background: Campylobacteriosis is a major zoonotic and foodborne disease (FBD), posing a substantial social and health economic burden on human health. Burden of disease (BoD) studies, which increasingly use the disability-adjusted life years (DALYs) metric, provide comprehensive insights into disease effects. However, the complexity of DALY calcul...

Full-text available
The pressure global food systems exert on the environment has amplified over time, following the growth of the human population, changes in the food consumption patterns and intensification of the production systems. Without changes in food systems, an overpressure on agriculture and food production will be unavoidable, with inevitable consequences...

Background Diarrheal diseases substantially affect public health impact in low- and middle-income countries (LMIC), particularly in Africa, where previous studies have indicated a lack of comprehensive data. With a growing number of primary studies on enteric infections in Africa, this study aimed to estimate the incidence and mortality of diarrhea...

Acute childhood diarrhea is one of the leading causes of childhood morbidity and mortality in sub-Saharan African countries. Entamoeba histolytica and Giardia lamblia are the common cause of childhood diarrhea in the region. However, there are only few studies on protozoa causing diarrhea in sub-Saharan African countries. This study was conducted t...

Knowledge about the extent of the COVID-19 mortality burden is important to inform policy-making decisions. To gain greater insights into the population health impact of COVID-19 mortality, Years of Life Lost (YLL) can be estimated. We aimed to determine YLL linked to COVID-19 over the first two years (March 2020–March 2022) of the pandemic in Cypr...

Previous efforts to estimate the burden of fatigue-related symptoms due to long COVID have a very high threshold for inclusion of cases, relative to the proposed definition from the World Health Organization. In practice this means that milder cases, that may be occurring very frequently, are not included in estimates of the burden of long COVID wh...

Objectives: Within the framework of the burden of disease (BoD) approach, disease and injury burden estimates attributable to risk factors are a useful guide for policy formulation and priority setting in disease prevention. Considering the important differences in methods, and their impact on burden estimates, we conducted a scoping literature re...
Article
Exposure to chemical contaminants found in foods has been associated with various adverse health effects. Burden of disease studies are increasingly used to estimate the public health impact of such exposures. The aims of this study were to estimate the burden of disease due to dietary exposure to four chemicals in France in 2019 (lead (Pb), cadmiu...

Background Public health surveillance data do not always capture all cases, due in part to test availability and health care seeking behaviour. Our study aimed to estimate under-ascertainment multipliers for each step in the reporting chain for COVID-19 in Toronto, Canada. Design and methods We applied stochastic modeling to estimate these proport...

Chapter
Foods can be an important source of exposure to chemicals harmful to humans. To identify and prioritize effective food safety strategies, and allocate resources to the interventions with maximum public health benefit, policy makers need evidence on which hazards cause the highest burden of disease in the population. The Disability Adjusted Life Yea...

Recent estimates have reiterated that non-fatal causes of disease, such as low back pain, headaches and depressive disorders, are amongst the leading causes of disability-adjusted life years (DALYs). For these causes, the contribution of years lived with disability (YLD) - put simply, ill-health - is what drives DALYs, not mortality. Being able to...

Salmonella spp. remains the most significant foodborne pathogen in south Brazil, but its epidemiology tends to change over time. Using official and surrogate data, a microbial subtyping model attributed different Salmonella serovars to laying hens, pigs, broilers, and turkeys from 2005 to 2015 in Rio Grande do Sul (RS). Additional to the subtyping...

Estimates of burden of foodborne diseases are important for prioritizing food safety policy at national and international levels. Estimating burden of foodborne diseases is complex: It requires data from many sources and relies on many assumptions. In 2015, the World Health Organization Foodborne Disease Burden Epidemiology Reference group (WHO/FER...

In the past, food-based dietary guidelines (FBDGs) were derived nearly exclusively by using systematic reviews on diet-health-relationships and translating dietary reference values for nutrient intake into foods. This approach neglects many other implications that dietary recommendations have on society, the economy and environment. In view of pres...

Arsenic is a naturally occurring metalloid in soil, air, water and food in organic and inorganic forms. Several epidemiological studies have shown that inorganic arsenic (i-As) is carcinogenic to humans. Previous studies have raised concern about dietary i-As exposure from various sources, including brown rice. We estimated the burden of disease in...

Despite increased political attention, foodborne diseases still cause a substantial public health, economic, and social burden worldwide. Children younger than 5 years, people living in developing regions, and in the poorest areas of the world are disproportionally affected, bearing a large proportion of the global burden of foodborne disease. Yet,...

Background: Toxoplasma gondii is an important foodborne zoonotic parasite. Meat of infected animals is presumed to constitute a major source of human infection and may be a driver of geographical variation in the prevalence of anti-T. gondii antibodies in humans, which is substantial in the Nordic-Baltic region in northern Europe. However, data on...
