  1. Research Theme 4: Food storage, value addition and mycotoxin management AfricaRising Research Theme 4 Team Dar es Salaam, June 30, 2016

  2. Team Members Research theme 4 Storage and Nutrition • Adebayo Abass and team Mycotoxins • George Mahuku and team Integrated with: Research theme 1: Fertilizer and maize variety trials • Job Kihara and Team Research theme 8: Poultry feed formulations • Ben Lukuyu and Team

  3. Importance of food storage and mycotoxin management • To minimize: • Quantitative losses (food security: accessibility, affordability) • Qualitative losses (nutritive value and safety of food) • Financial losses and safeguard trade - especially international trade • So that the harvested food reaches the consumer to fulfill satisfaction in terms of quality, quantity and safety • But due to absence of adequate; • Pre- & post-harvest management technologies , including storage infrastructure • Improved processing methods and machinery • Market facilities • Awareness

  4. Importance of food storage and mycotoxin management • Significant post-harvest losses are experienced (20 – 40% in Africa) • Health problems from consumption of unsafe foods – mycotoxins (cancer, child stunting, immune suppression, blood and nerve defects, instant death, etc.) • Rejection of agricultural products with higher than the regulated limits for mycotoxins (aflatoxin in Kenya) – loss of market opportunities

  5. What are the possible impacts of food losses and high mycotoxin in foods? • Insufficient household foods for 365days • Poor quality of nutrients in household diets • Unsafe foods • Malnutrition in children, lactating women and the elderly. • Frail or sickly population

  6. Post-harvest loss assessment: characteristics of a maize-based system Abass et al., 2014

  7. What has been done in Babati? Assessing post harvest losses during storage (2014-2016); Quantifying mycotoxins (aflatoxin and fumonisin) in field and storage; Testing improved dying, shelling and storage technologies Creating awareness among stakeholders on post harvest losses, health hazards from mycotoxins and mitigation strategies; Developing the Aflasafetechnology for Tanzania Assessing GAP measures for managing mycotoxins (Link with Theme 1) Assessment of nutritional status of the diet for the population of maize based farming system (children and the vulnerable groups)

  8. Assessment of post-harvest losses in maize Conducted in Long, Sabilo and Seloto, involving 60 farmers and 5 tons of maize Percentage loss of maize stored for 8 months

  9. Assessment of nutritional status of farm households in maize-based farming system (children and the other vulnerable groups) Assessment of nutritional status of pregnant women in Babati Mid-upper arm circumference (MUAC)

  10. Can adequate food storage lead to better health outcomes? A storage experiment with farmers from 2013-2014: Assessment of the nutritional status of children of participating and non-participating households

  11. Mycotoxin Awareness is very low

  12. Prevalence of aflatoxinand fumonisin in maize in the field and stores

  13. Integration with Research theme 1: samples collected for mycotoxin analysis Samples collected from Research theme 1 Fertilizer and variety treatments

  14. Integration with Research theme 1: samples collected for mycotoxin analysis • Low levels of aflatoxin and fumonisin • Monitoring continuing

  15. Aflatoxin prevalence and levels in Feed ingredients

  16. Interventions testing Aflatoxin bio-control • Use of Aspergillusflavus strains that do not produce toxins • Naturally outcompete the toxic producing strains, reducing their population and hence aflatoxin • Villages selected in Babati: • Sabilo • Sangaiwe • Matufa • Hallu

  17. Aflasafe Development Sterilizing sorghum Coating sorghum Packaged Product ready for trials

  18. Awareness creation Awareness creation to selected farmers during site selection Farmers with biocontrol product Atoxigenic strain imobilized on sorghum sporulates A farmer applying biocontrol product

  19. Ready to Scale Technologies PICS Bags Long Village farmer Mr. Emmanuel Margwe with his maize stored in PICS bags. Farmers who attended field day witnessing good quality maize stored in PICS bags from September 2014. Demonstration on PICS storage bags how to use, their benefits and supplier contacts. • 98.04% of 51 farmers interviewed will continue using PICS for maize storage (February –March 2016)

  20. Ready to Scale Technologies Maize shelling machine (Diesel Engine) • Can shell an average of 500 kg per hour • In Target villages 96.08% farmers interviewed had used shelling machine • Very efficient – farmers have more time to attend to other activities

  21. Interventions/Scaling-up • Warehousing • Scale up storage of maize in improved hermetic bags initiated in three villages • Farmers can store for long periods to leverage better price (price monitoring) • Reduce losses due to storage pests (quarterly sampling) • Reduce risks from aflatoxin contamination (quarterly sampling) • Maize threshing machine • Saves time (500kg per hour) compared to traditional methods • Reduces labour input by women, fewer people needed • Reduces waiting time for threshing (in the open), hence reduces chances for mycotoxin contamination • (Scaling expert required to design further experiments)

  22. Ready to Scale Technologies Collapsible drier cacoon (CDC) • Farmers see the benefit of using CDCs • ~49% said they would invest

  23. Interventions/Scaling-up • Product development: Introducing high protein-content recipe using locally available materials –common bean: Long Seloto and Sabilo • Creation of awareness of nutrition problem (stunting, wasting, lack of protein in diets, etc) • New highly nutritious foods developed (6); lab analysis of new foods for nutrient density • Support the establishment of pilot processing & innovation platform centers • Sensory evaluation and community-based nutrition training

  24. At least four manuscripts will be prepared for publication in international peer reviewed journals in 2015/2016 as one of the deliverables for this project (Research Theme 4).
