  1. Aflatoxin Outlook in Mozambique Prepared for COMESA aflatoxin workshop in Malawi Joao Augusto, Ranajit Bandyopadhyay, Juliet Akello, Joseph Atehnkeng March 11, Lilongwe, Malawi

  2. Outline • Background information about aflatoxins in Mozambique • Aflatoxin regulations and monitoring in Mozambique • Ongoing research and technology options • Gaps to be addressed

  3. Background Information about aflatoxins in Mozambique Late 1970’s – Intake of aflatoxin contaminated food, especially from groundnut, linked to high prevalence of liver cancer in Southern Mozambique Late 1990’s to date – Rejection of groundnut and groundnut products by the EU for exceeding aflatoxin legal limits

  4. Background Information about aflatoxins in Mozambique Notifications of Mozambican groundnut products by EU market: Source: RASFF portal, 2011

  5. Background Information about aflatoxins in Mozambique Late 1970’s – Intake of aflatoxin contaminated food, especially from groundnut, linked to high prevalence of liver cancer in Southern Mozambique Late 1990’s to date – Rejection of groundnut and groundnut products by the EU for exceeding aflatoxin legal limits Survey in 2013 – identification of aflatoxin hot-spot areas for maize and groundnut in central and northern Mozambique (USAID-Moz grant)

  6. Outline • Background information about aflatoxins in Mozambique • Aflatoxin regulations and monitoring in Mozambique • Ongoing research and technology options • Gaps to be addressed

  7. Aflatoxin regulations and monitoring in Mozambique According to FAO (1994) – There are aflatoxin regulations in Mozambique (but not enforced) Universidade Lurio (UniLurio) in northern Mozambique – Aflatoxin testing and monitoring for different crops (but the lab is not accredited) Madal Ltd in central Mozambique – private company working with some 3,000 groundnut farmers (sorting and aflatoxin testing for the farmers)

  8. Outline • Background information about aflatoxins in Mozambique • Aflatoxin regulations and monitoring in Mozambique • Ongoing research and technology options • Gaps to be addressed

  9. Aflatoxin surveillance in Mozambique • Conducted at harvest, May-June, 2013 • In Northern and Central regions, but with emphasis to Nacala Corridor • Selection criteria for the locations: (a) maize and groundnut in the same area (but sampling will be as far as possible from each sampling point); (b) number of districts in each province; (c) distribution in altitude; (d) cropping systems; and (e) accessibility • Materials: “Sampling procedures” for survey, “Sampling questionnaires” for each survey group, colored-printed and laminated mycotoxin factsheets in Portuguese, GPS handsets, etc

  10. Objectives of the surveillance • Estimate magnitude of aflatoxins • Determine geographic distribution of aflatoxins • Facilitate planning

  11. Determine magnitude of aflatoxins n=283 n=307

  12. Determine magnitude of aflatoxins

  13. Distribution of aflatoxins: by region

  14. Distribution of aflatoxins: by province

  15. Distribution of aflatoxins: by levels % g’dnut samples at harvest (n=283) % maize samples at harvest (n=307)

  16. Awareness raising about aflatoxins

  17. Outline • Background information about aflatoxins in Mozambique • Aflatoxin regulations and monitoring in Mozambique • Ongoing research and technology options • Gaps to be addressed

  18. Identifying, selecting atoxigenic strains for aflatoxin biocontrol • More than 400 atoxigenic L-strains of Aspergillus flavus identified from maize and groundnut • Most competitive and widely distributed atoxigenic strains, with no toxigenic member in their VCG groups, will be selected • Selected 8-12 VCG strains to be formulated in aflasafe-Moz biocontrol products for testing in farmers’ fields in 2014 crop growing season

  19. Outline • Background information about aflatoxins in Mozambique • Aflatoxin regulations and monitoring in Mozambique • Ongoing research and technology options • Gaps to be addressed

  20. Gaps to be addressed • Infrastructure and human capacity building, polices Equipping and certifying laboratories  Recruiting and training Mozambican technicians and students  Awareness raising  Advocacy, regulations and enforcement
