The document discusses the critical importance of food safety in low- and middle-income countries, emphasizing its role in achieving sustainable development goals (SDGs) and highlighting new findings from systematic literature reviews on food safety interventions. It identifies major challenges, including inadequate policies, gaps in food safety capacity, and economic burdens due to foodborne diseases, while proposing market-led, evidence-based approaches for improvement. The presentation calls for comprehensive actions to enhance food safety systems to protect public health, particularly within informal markets.

2. Presentation
 Why food safety in low-and middle-income countries
(LMIC) matters
 New findings on food safety
 Systematic Literature Review on food safety
interventions
 What doesn’t work
 What may work
 Conclusions

3. Traditional Image of Food Safety
Food Safety critical to ACHIEVING the SDGs
 Food safety is integral to:
 Food safety (practice) contributes to:
3
Food safety is integral to the SDGs
The lack of explicit attention to food safety in the SDGs stems from the low evidence base on the burden of foodborne
disease and the overall low awareness of development practitioners about the economic significance of unsafe food.

9. Main messages
When food safety has been on the development agenda, this has
primarily been in relation to trade. This needs to change.
We often see a policy vacuum and leadership void. Crisis
management is more common than risk management.
The gap between food safety capacity and actual needs is especially
problematic among rapid urbanizing lower middle-income
countries.
There are appropriate food safety public policies and cost-effective
investments for countries at all economic levels.

10. Domestic costs may be 20 times trade
costs
Cost estimates for 2016 (US$
billion)
Productivity loss 95
Illness treatment 15
Trade loss or cost 5 to 7
‘Productivity Loss’ =
Foodborne Disease DALYs x Per Capita GNI
Based on WHO/FERG & WDI Indicators Database
Illness treatment =
US$27 x # of Estimated foodborne illnesses
Trade loss or costs =
2% of developing country high value food exports

12. • Donor investment since 2010 less than $40 million a year. Small in
relation to burden and investments in other health areas
• Substantial focus on:
• National control systems
• Exports and other formal markets
• Chemical hazards
•
• Little focus on:
• Market-based and demand-led approaches
• Informal sector where most foods are sold
• Biological hazards and risks to human health
Main messages

13. 1. Health first: Better address the health of domestic
consumers dependent on informal markets.
2. Risk-based: Build capacity for well-governed,
evidence- and risk-based food safety systems.
3. Market-led: Harness marketplace drivers of
progress on food safety.
Call to action!

14. We can’t regulate our way to food safety
Regulations are needed but not enough
 100% of milk in Assam doesn’t meet standards
 98% of beef in Ibadan, 52% pork in Ha Noi, unacceptable
bacteria counts
 92% of Addis milk and 46% of Nairobi milk had aflatoxins over
EU standards
 36% of farmed fish from Kafr El Sheikh exceed one or more MPL
 30% of chicken from commercial broilers in Pretoria
unacceptable for S. aureus
 24% of boiled milk in Abidjan unacceptable S. aureus

15. We can’t modernise our way to food safety
Modern retail growing, traditional persisting
 Supermarketisation is slower than thought
 Formal sector food is not always safe
 Modern business models have often run into problems
– Co-ops, abattoirs, market upgrades

21. Room for improvement
• Failure to evaluate large scale investments
• Interventions without measuring outcomes – yet some
interventions make things worse
• Near-term, easy, un-important outcomes e.g. changes in
knowledge
• Reliance on self-reporting (e.g. diarrhoea)
• Short-term follow ups – no attention to sustainability
• Limited information on economic aspects – many unaffordable
• Lack of attention to incentives
• Limited attention to gender, equity and nutrition

22. Increasing concerns over food safety
Jabbar et al.; Lapar et al.
In seven developing countries studied
•Many/most reported concern over food
safety (40–97%)
•Willing to pay 5–10% premium for food
safety
•Younger, wealthier, town-residing,
supermarket shoppers willing to pay
more for safety
•Buy 20–40% less during animal health
scares

23. Pull approach
(demand for safe
food)
Push approach
(supply of safe
food)
Consumers recognize
& demand safer food
VC actors respond to
demand & incentives
Inform, monitor &
legitimize VC actors
Build capacity &
motivation of
regulators
Consumer campaign

consumers

• Greater consumer trust in milk
• 70% of traders in Assam are

• It benefited the economy by

• 1.5 million consumers

29. Take-home messages
 Huge health burden of foodborne disease
– Most due to microbes in fresh foods in wet markets
– Will get worse before it gets better
 Huge economic burden of foodborne disease
 Previous investments not in line with modern understanding
 Interventions successful in the short term
 Long-term, wide-reaching impacts likely require
 Training and technology
 Incentives
 Enabling environment
