Background: According to the World Health Organization, 600 million cases of foodborne disease occurred in 2010. To inform risk management strategies aimed at reducing this burden, attribution to specific foods is necessary. Objective: We present attribution estimates for foodborne pathogens (Campylobacter spp., enterotoxigenic Escherichia coli (ETEC), Shiga-toxin producing E. coli, nontyphoidal Salmonella spp., Cryptosporidium spp., Brucella spp., and Mycobacterium bovis) in three African countries (Burkina Faso, Ethiopia, Rwanda) to support risk assessment and cost-benefit analysis in three projects aimed at increasing safety of beef, dairy, poultry meat and vegetables in these countries. Methods: We used the same methodology as the World Health Organization, i.e., Structured Expert Judgment according to Cooke's Classical Model, using three different panels for the three countries. Experts were interviewed remotely and completed calibration questions during the interview without access to any resources. They then completed target questions after the interview, using resources as considered necessary. Expert data were validated using two objective measures, calibration score or statistical accuracy, and information score. Performance-based weights were derived from the two measures to aggregate experts' distributions into a so-called decision maker. The analysis was made using Excalibur software, and resulting distributions were normalized using Monte Carlo simulation. Results: Individual experts' uncertainty assessments resulted in modest statistical accuracy and high information scores, suggesting overconfident assessments. Nevertheless, the optimized item-weighted decision maker was statistically accurate and informative. While there is no evidence that animal pathogenic ETEC strains are infectious to humans, a sizeable proportion of ETEC illness was attributed to animal source foods as experts considered contamination of food products by infected food handlers can occur at any step in the food chain. For all pathogens, a major share of the burden was attributed to food groups of interest. Within food groups, the highest attribution was to products consumed raw, but processed products were also considered important sources of infection. Conclusions: Cooke's Classical Model with performance-based weighting provided robust uncertainty estimates of the attribution of foodborne disease in three African countries. Attribution estimates will be combined with country-level estimates of the burden of foodborne disease to inform decision making by national authorities. Author summary: The World Health Organization has presented estimates of the burden of foodborne disease and attribution percentages of zoonotic foodborne pathogens to food groups (e.g., beef, vegetables,..). To inform food safety decision making at the national level, these estimates should be combined, extended to pathogens with human reservoirs and provided at a more detailed level (e.g., drinking raw milk as one food product in the dairy group). We present a Structured Expert Elicitation study using the same protocol as the World Health Organization (Cooke's Classical Model) to attribute foodborne disease of selected pathogens (Campylobacter spp., enterotoxigenic Escherichia coli, Shiga-toxin producing E. coli, nontyphoidal Salmonella spp., Cryptosporidium spp., Brucella spp., Mycobacterium bovis) to different food types and food products in the beef, dairy, poultry and vegetable groups in three African countries (Burkina Faso, Ethiopia, and Rwanda). Individual experts' uncertainty assessments resulted in modest statistical accuracy and high information scores, that is concentrated in small ranges, suggesting overconfident assessments. Nevertheless, the optimized item-weighted decision maker was statistically accurate and informative. Cooke's Classical Model with performance-based weighting provided robust uncertainty estimates of the attribution of foodborne disease in three African countries. [ABSTRACT FROM AUTHOR]

In many low‐income countries, such as Burkina Faso, rates of malnutrition are high among children. Research indicates that animal source foods may provide important elements to improve growth and development of young children, especially during periods of rapid development, such as the first 1,000 days of life. The Un Oeuf study is designed to test an innovative behaviour change communication strategy to increase egg consumption in children 6–24 months in Burkina Faso, thereby improving dietary diversity and nutritional outcomes. This 1‐year cluster randomised controlled trial tests whether the gifting of chickens by a community champion directly to a child, combined with a behaviour change package of integrated poultry management and human nutrition trainings, can significantly increase egg consumption among children under 2 years in rural communities where egg consumption is very low. The nutrition‐sensitive behaviour change package is designed to increase egg consumption through improving livestock production, women's empowerment and food security at the household level. This paper presents a detailed account of the study design and protocol for the Un Oeuf study, alongside a description of the study population. Baseline data show a study population with high rates of malnutrition (stunting 21.6%, wasting 10.8% and underweight 20.4%) and a very low rate of egg consumption—less than 10% among children. Although poultry production is quite common, egg consumption is low reportedly because of cultural norms, including widespread practice of allowing eggs to hatch and a lack of knowledge about the nutritional benefits of egg consumption.

BACKGROUND AND OBJECTIVES: Malnutrition is a significant contributor to child morbidity and mortality globally. Egg consumption has been associated with improved child nutrition yet is rare in rural, resource-poor settings. We test the effects of a culturally tailored behavior change intervention to increase child egg consumption. METHODS: A 3-arm cluster randomized controlled trial was conducted in rural Burkina Faso with 260 mother-child dyads. Children aged 4 to 17 months from 18 villages were included; those with reported history of malnutrition or egg allergy were excluded. Each child in the full intervention arm received 4 chickens, and mothers received the 10-month behavior change package. Participants in the partial intervention arm received only the behavior change package. RESULTS: In this analysis of 250 children, the full (β = 4.3; P = 6.6 3 10212) and the partial (β = 1.0; P = .02) interventions significantly increased egg consumption. The full intervention also significantly increased poultry production (β = 11.6; 95% confidence interval 8.3-15; P = 1.1 3 1025) and women's decision-making about eggs (β = .66; P = .02), and significantly decreased wasting (β = .58; P = .03) and underweight (β = .47; P = .02). CONCLUSIONS: The culturally tailored behavior change package significantly increased child egg consumption. When coupled with the gift of chickens, the behavior change intervention yielded a greater increase in egg consumption and significantly reduced wasting and underweight. Behavior change strategies to increase egg consumption should be considered among nutrition and health programs in resource-poor settings where poultry is available. [ABSTRACT FROM AUTHOR]
