Innovation triggers. ICRISAT and NASFAM (see Box 4) supported by USAID, Government<br />

extension services and Tw<strong>in</strong> Trad<strong>in</strong>g have worked closely together as partners s<strong>in</strong>ce 2003 <strong>in</strong><br />

assist<strong>in</strong>g farmers to access high-value FairTrade export markets <strong>in</strong> the EU. It was realised that<br />

reduc<strong>in</strong>g aflatox<strong>in</strong> levels dur<strong>in</strong>g production and be<strong>in</strong>g able to identify aflatox<strong>in</strong> contam<strong>in</strong>ation<br />

of a groundnut consignment at source reduces not only the risk of shipment rejection but also<br />

results <strong>in</strong> ma<strong>in</strong>tenance of market share on the <strong>in</strong>ternational market.<br />

Stakeholder <strong>in</strong>teractions and <strong>in</strong>terventions. The stakeholder partnership comb<strong>in</strong>ed forces<br />

to <strong>in</strong>crease the productivity of groundnuts by provid<strong>in</strong>g improved varieties and improv<strong>in</strong>g<br />

smallholder management practices to <strong>in</strong>crease yields and reduce aflatox<strong>in</strong> contam<strong>in</strong>ation.<br />

This required the development of a system of grades and standards enabl<strong>in</strong>g participation<br />

<strong>in</strong> regional and <strong>in</strong>ternational markets and assistance <strong>in</strong> standards certification as well as the<br />

development of a traceability system so that the areas <strong>in</strong> which aflatox<strong>in</strong>s were a problem could<br />

be easily identified. Only then could a high-value market <strong>in</strong> Europe for smallholder-produced<br />

groundnuts be accessed. Improv<strong>in</strong>g productivity and develop<strong>in</strong>g standards certification<br />

<strong>in</strong>volved the establishment of on-farm demonstrations to tra<strong>in</strong> farmers <strong>in</strong> improved agronomic<br />

practices. Production standards were developed to ensure that farmers follow improved<br />

management practices to reduce the <strong>in</strong>cidence of the aflatox<strong>in</strong>-caus<strong>in</strong>g fungus. This <strong>in</strong>volved<br />

ICRISAT tra<strong>in</strong><strong>in</strong>g NASFAM and Government extension staff to understand the critical po<strong>in</strong>ts<br />

<strong>in</strong> the management of aflatox<strong>in</strong> dur<strong>in</strong>g production, harvest and postharvest handl<strong>in</strong>g (Siambi<br />

et al., 2008). Although farmers often prefer the variety Chalambana, because of its light sk<strong>in</strong><br />

colour, low oil content and large kernel size, which makes shell<strong>in</strong>g easier, it is susceptible to the<br />

fungus that causes aflatox<strong>in</strong> contam<strong>in</strong>ation. Improved varieties are higher yield<strong>in</strong>g and have<br />

some resistance to contam<strong>in</strong>ation. NASAFM and ICRISAT have worked closely to ensure certified<br />

seed of new varieties CG7, Chalambana 2000 and JL24 is accessible by farmers. Unfortunately<br />

weather conditions can exacerbate the aflatox<strong>in</strong> problem and postharvest handl<strong>in</strong>g can be<br />

critical <strong>in</strong> manag<strong>in</strong>g aflatox<strong>in</strong> levels. ICRISAT was <strong>in</strong>strumental <strong>in</strong> develop<strong>in</strong>g pyramid structures<br />

on which harvested groundnuts are placed, leaves upwards, so that pods dry and ra<strong>in</strong>water<br />

runs off without damag<strong>in</strong>g the pods. These pyramids are now widely used by farmers.<br />

Food safety requirements of the EU have a m<strong>in</strong>imum acceptance level (MAL) of aflatox<strong>in</strong><br />

contam<strong>in</strong>ation of 4 parts per billion (ppb) that requires a systematic approach to identify<br />

and elim<strong>in</strong>ate the sources of contam<strong>in</strong>ation. This required the establishment of laboratory<br />

facilities to establish a system for quality control for groundnuts purchased by NASFAM. Dur<strong>in</strong>g<br />

the early stages 200-g samples were taken from every 50-kg bag of groundnuts purchased.<br />

These were labelled to identify the grower and the centre from where it was purchased.<br />

The cod<strong>in</strong>g, record<strong>in</strong>g and gr<strong>in</strong>d<strong>in</strong>g of samples was undertaken by ICRISAT-Malawi and then<br />

sent to ICRISAT-India, for aflatox<strong>in</strong> contam<strong>in</strong>ation measurement. Test results were used for<br />

product differentiation and target<strong>in</strong>g different markets that permitted different MALs. When<br />

the traceability system was proved, analysis as undertaken <strong>in</strong>itially by ICRISAT- Malawi, until<br />

NASFAM was able to establish its own laboratory with staff tra<strong>in</strong>ed to measure aflatox<strong>in</strong>.<br />

NASFAM Associations are grouped by Market Access Centres, which provide support to<br />

members. Clubs sell their produce at designated Market Centres. This allows for traceability<br />

as samples are collected from groundnuts purchased by NASFAM and analysed for aflatox<strong>in</strong><br />
