Risk Ranking for Foodborne Microbial Hazards in New Zealand: Burden of Disease Estimates

Abstract

Priority setting for food safety management at a national level requires risks to be ranked according to defined criteria. In this study, two approaches (disability-adjusted life years (DALYs) and cost of illness (COI)) were used to generate estimates of the burden of disease for certain potentially foodborne diseases (campylobacteriosis, salmonellosis, listeriosis (invasive, perinatal, and nonperinatal), infection with Shiga toxin-producing Escherichia coli (STEC), yersiniosis, and norovirus infection) and their sequelae in New Zealand. A modified Delphi approach was used to estimate the food-attributable proportion for these diseases. The two approaches gave a similar ranking for the selected diseases, with campylobacteriosis and its sequelae accounting for the greatest proportion of the overall burden of disease by far.

“…In New Zealand, a country which has a high rate of reported campylobacteriosis compared to other developed countries, Campylobacter infections and sequelae have been recently estimated to cost the public health system NZ $74 million annually (23). In the United States, Campylobacter infections cause US $1.7 billion in annual costs of illness (2).…”

Systematic review of foodborne burden of disease studies: Quality assessment of data and methodology

“…Table 1 shows the number of foodborne burden of disease studies per WHO region, subdivided into agent-based, outcome-based and risk-factor based approaches. The majority of burden of disease studies relevant to foodborne disease used the agent-based approach (n = 19; (Budke et al, 2004;Fewtrell et al, 2005Fewtrell et al, , 2004Furst et al, 2012;Gkogka et al, 2011;Haagsma et al, 2008;Havelaar et al, 2000Havelaar et al, , 2012Havelaar et al, , 2007bHavelaar et al, , 2004Kortbeek et al, 2009;Lake et al, 2010;Lokuge et al, 2004;Praet et al, 2009;Reij et al, 2009;Torgerson et al, 2008;Valent et al, 2004;Verhoef et al, 2012)). 1) Which data sources were used to assess mortality, morbidity and disability?…”

Subsequently, most studies applied scaling factors to estimate the total number of laboratoryconfirmed cases (i.e.…”

Country specific life expectancy tables were also used by eight studies (Gkogka et al, 2011;Haagsma et al, 2008;Havelaar et al, 2004;Kortbeek et al, 2009;Lake et al, 2010;Nafar et al, 2008;Reij et al, 2009;Torgerson et al, 2008).
