Abstracts of Presentations to the Working Session on Improving Predictive Modeling of Mycotoxin Risk for Africa Held at the 3rd ASM2022 on 7 September 2022, in Stellenbosch, South Africa.

In 2008, the African Postharvest Losses Information Systems project (APHLIS, accessed on 6 September 2022) developed an algorithm for estimating the scale of cereal postharvest losses (PHLs). The relevant scientific literature and contextual information was used to build profiles of the PHLs occurring along the value chains of nine cereal crops by country and province for 37 sub-Saharan African countries. The APHLIS provides estimates of PHL figures where direct measurements are not available. A pilot project was subsequently initiated to explore the possibility of supplementing these loss estimates with information on the aflatoxin risk. Using satellite data on drought and rainfall, a time series of agro-climatic aflatoxin risk warning maps for maize was developed covering the countries and provinces of sub-Saharan Africa. The agro-climatic risk warning maps for specific countries were shared with mycotoxin experts from those countries for review and comparison with their aflatoxin incidence datasets. The present Work Session was a unique opportunity for African food safety mycotoxins experts, as well as other international experts, to meet and deepen the discussion about prospects for using their experience and their data to validate and improve agro-climatic risk modeling approaches.

Handwashing knowledge, attitudes, and practices in Ghana.

Introduction: Handwashing has been recognized as a convenient, effective, and cost-effective means of preventing communicable diseases. However, many people overlook the importance of handwashing when engaging in activities that require handwashing due to various factors. The objectives of this study were to assess the level of handwashing knowledge, attitudes, and practices and determine their relationships and how they are affected by sex, educational background, and age. Methods: A cross-sectional survey was conducted among 636 respondents who received and completed an online questionnaire that was disseminated to the contacts of the researchers via WhatsApp, Email, LinkedIn, and Facebook. Respondents were presented with several statements to assess their handwashing knowledge, attitudes, and practices. Results: Overall, 82.2% of respondents had good knowledge, 91% had a positive attitude, and 48.4% adhered to good handwashing practices. Having a high school level of education (OR = 0.193, p = 0.034.), (OR = 0.145, p = 0.000) and (OR = 0.448, p = 0.049) decreased the likelihood of having good knowledge, positive attitudes, and good practices than in persons with tertiary level education. Predictors of good handwashing practices were knowledge (OR = 1.059, p = 0.37) and attitude (OR = 1.095, p = 0.000). These results suggest that having a higher level of education could increase a person's knowledge and attitude, which in turn enhances the likelihood that the person would adhere to most handwashing and hand hygiene practices. Conclusions: Enhancing people's handwashing practices requires positive attitudes and good knowledge about handwashing. These need to be complemented by enhanced access to handwashing facilities and innovative measures to enforce and encourage compliance.

Advocacy for scaling up biofortified crops for improved micronutrient status in Africa: approaches, achievements, challenges and lessons.

Biofortification is an approach used to increase micronutrient content of crops through agronomic practices, conventional or modern biotechnology. Through a plethora of projects, partnerships were formed to advocate for policy changes, and increased investments in research, production and utilisation of biofortified crops. One of such projects is the Building Nutritious Food Baskets project, which has been appraised in order to draw and share successes, challenges and lessons for the improvement of similar future projects to achieve substantial impacts. The paper provides an overview of the role of biofortification in addressing nutritional challenges and highlights the efficacy of biofortified crops in improving micronutrient status. Through advocacy at the African Regional and sub-regional levels, awareness has been created on biofortification among governments, investors, development partners, farmers and consumers. This awareness has resulted in the incorporation of biofortification in some key policies, strategies and investment programmes. Key lessons learnt from regional advocacy are (1) in order to integrate biofortification in regional policies, strategies and programmes, it is important to identify champions from key and strategic regional organisations as they provide information on potential opportunities for influencing policies, (2) having a common advocacy message helps to highlight the role of biofortification in contributing to the prevention of micronutrient problems as well as evidence of impact on nutrition outcome, (3) champions need to be allocated a budget to support their advocacy work and (4) to engender adoption of biofortification, it is important to align biofortification with relevant initiatives as well as ongoing opportunities for advocacy.

Food safety concerns of fast food consumers in urban Ghana.

In Ghana, out-of-home ready-to-eat foods including fast food generally have been associated with food safety problems. Notwithstanding, fast food production and consumption are increasing in Ghana and therefore this study sought to determine the food safety issues of importance to consumers and the extent to which they worry about them. First, through three focus group discussions on consumers' personal opinions about food safety issues, some emergent themes were obtained, which were used to construct an open-ended questionnaire administered face-to-face to 425 respondents systematically sampled from 20 fast food restaurants in Accra. Findings showed that most fast food consumers were concerned about food hazards such as pesticide residue in vegetables, excessive use of artificial flavour enhancers and colouring substances, bacterial contamination, migrated harmful substances from plastic packages, and general unhygienic conditions under which food is prepared and sold. Consumers also raised concerns about foodborne diseases such as cholera, typhoid, food poisoning, diarrhoea, bird flu and swine flu. The logistic regression model showed that being male increased the likelihood of worrying about general food safety issues and excessive use of flavour enhancers than in females while being youthful increased the likelihood of being worried about typhoid fever than in older consumers. These findings imply that consumers in urban Ghana are aware and concerned about current trends of food safety and foodborne disease challenges in the country. Therefore, efforts targeted at improving food safety and reducing incidences of foodborne diseases should not only focus on public awareness creation but should also design more comprehensive programmes to ensure the making of food safety rules and guidelines and enforcing compliance to facilitate availability and consumers' choice of safe foods.
