Aflatoxins: Finding Solutions for Improved Food Safety Presentation by Laurian Unnevehr

  1. 1. Finding Aflatoxin Solutions Introduction Laurian Unnevehr IFPRI November 5, 2013
  2. 2. Aflatoxins– Why Now? • 2000s – Emerging evidence of greater health risks • 2002 – Decline in African exports to EU over time as standards rising • 2004 – Acute outbreak and deaths in eastern Kenya • 2007– Purchase for Progress finds local suppliers can’t meet standards • 2011– PACA established to foster policy response Source: IITA Images
  3. 3. A Persistent Problem • Higher incidence in tropics for many crops • Higher exposure from greater consumption of staple foods • Little knowledge of risks or control methods • Control methods add costs and not consistently rewarded
  4. 4. Risks and Barriers Health • Acute health hazard in high amounts • Chronic health risk for – Cancer – Child stunting – Immune suppression Markets • Barrier to trade • Barrier to commercial market development
  5. 5. Solutions Must be Multi-Faceted Technologies • Better crop and postharvest management • New technologies – Plant host resistance – Biocontrol – Better tests Policies and Markets • Risk assessment and monitoring to inform education, intervention • Market incentives and value chain interventions
  6. 6. Aflatoxin Control Benefits Are Synergistic Health Product ivity Trade Reduced aflatoxin levels support expanded regional and global trade. Trade provides incentives for control. Reduced aflatoxins means fewer acute and chronic health effects and supports improved nutrition. Market Development Improved crop husbandry, post-harvest management lead to higher yields and reduced aflatoxins Reduced aflatoxin levels support market development for processed foods, feeds. Market incentives support adoption of aflatoxin control.
