The impact of hand shelling in Malawi:Why groundnuts?
The impact of hand shelling in Malawi:
Why groundnuts?
•4 billion hours spent hand shelling groundnuts each year in Africa;
•Groundnuts are the primary source of protein for ca. 0.5 billion people;
•Domestic consumption & regional trade are growing;
•International nut trade renewing interest in Africa; • Aflatoxins are a major constraint to re-enter regulated markets;
•Regional markets in Africa are starting to tighten aflatoxin controls; • Malawi one of 5 PACA pilot countries• Malawi a net exporter of groundnuts
•Significant commitment and coordinated investment needed to establish and secure value chain reputations for quality groundnuts.
The collapse of African groundnut exports to international markets.

40% in the 1970’s
90% in the 1960’s
<5% by 2005
•US, China, & Argentina dominate exports;
•Co-ordinated supply chains developed for regulated exports;
•Africa exports collapsed;
•But production & regional trade is now increasing;
•Africa overtaken India as 2nd largest producer.

Changes in EU market requirements for groundnuts
•Significant investment needed to re-enter regulated markets eg: EU, South Africa & with PACA support East Africa

Malawi groundnut production & export
Export (tonnes)
Pro-duction (tonnes)
• 1970’s > 40,000 mt pa exported to Europe;
•1980’s exports & production collapsed;
•2000’s production revived;
•Hand shelling for confectionary markets;
•Priority crop for 2012 National Export Strategy;
•75% consumed by domestic market;
•Very little is wasted (NB. Current food shortage).

Malawi exports to high & low enforcement countries (2004 -2013)
•Most exports now go to low enforcement markets;•Almost no exports now to high enforcement markets;•Some uncertainty about the current volumes of informal
exports;•Note the drought years (circles) NB. 2015 poor rains (2.8
million people in need for food aid - FEWS).

4 billion hours of hand shelling per year across Africa
On farm hand shelling
•Poor storage & drying;•Shells are soaked to ease hand shelling;•Limited sorting of contaminated nuts.
•Groundnut flour had most contaminated samples;
• 73% > EU 4ppb level.
• 25% above 100ppb • highest = 3871 ppb•70% of families add
groundnut flour to meals ca. twice/ week.

On farm hand sorting:Not enough contaminated crop is removed
from the food chain!
Contaminated nuts are eaten by informal consumers
Formal vs informal value chains
Controls in formal value chains:•Protect consumers in export, local
retail & other markets;•Eg: Locally produced safe RUTFs for
severely malnourished children.
Informal value chains:•Improving quality will impact all
consumers;•There is little awareness or food safety
& control of aflatoxin;•Few incentives to reduce aflatoxin
levels; •Crushing contaminated crop for oil &
meal relevant to formal & informal chains.

Improve infrastructure, awareness & standards
Partnerships needed:• Malawi Partnership for
Aflatoxin Control (MAPAC) established;
• Aligned to PACA;
• Formal value chain partnerships eg: Afri-Oils encouraged;
• Investment needed to address farmer drying, storage, irrigation etc.

In-shell trading, backed by a certified warehouse and buyer or seller contracts needed to improve confidence in quality groundnuts from Malawi.

Aflatoxin exposure and infection
• Three “states” with respect to Aflatoxin in groundnuts: (OK; Exposed; Infected.)
• Nuts flow into each inventory stage with some distribution of OK, Exposed, Infected
• While in each stage, nuts “leak”…– From OK to Exposed through
exposure flow– From exposed to infection
through infection flow• Nuts that move to next stage
of supply chain reflect cumulative impact of exposure and infection
Exposure here… …Can show up
as infection here!

Proportion of all Afri-Nut samples in 2013: • 26% > 4ppb; &• 16% > 15ppb.
ICRISAT (2009) Groundnuts sampled with > 4ppb aflatoxin:
•43% at farmers households;
•49% from local markets;
•58 – 60% from shops and supermarkets;
•41% from warehouses; •73% of flour samples.
Examples of aflatoxin sampling results for raw peanuts in Malawi (2009 & 2013).
Recommendations:
Establish financial services to facilitate buying/ post harvest centres: •Pilot of buying and post harvest processing centres supported by economic analysis;
•Review appropriate financial services / market pull e.g. Warehouse receipts;
•Explore wider services e.g drying and crushing in ACE certified warehouse storage of nuts in shell.
• Majority of market led work re: aflatoxin and groundnuts focuses on building export value chains;
• Export driven groundnut market system and value chains fail to serve the needs of smallholder producers and consumers;
• Need for a food safety focus in local food systems and farm level infrastructure as well as export value chains.
Conclusion:Importance of food safety in all food systems
There is a need for a cross sector approach to the issue
of aflatoxin
