2. Presentation Summary Overview of coffee and safety concerns
Broad look at the emerging threat of mycotoxins to food safety
Local coffee industry response to mycotoxin in coffee
3. The Coffee Industry After oil, coffee is the most widely traded commodity in the world
Provides employment for some 20 million persons worldwide
Most widely consumed beverage
Grown in the tropics
4. Jamaica’s Coffee Industry Coffee is the second most important agricultural product
Generates earnings of over US $30 M from export
Employs over 50,000 person directly with over 250, 000 dependents
Best coffee in the world
5. Coffee plant
6. Coffee berries
7. Coffee beans
8. Areas of Concern Chemical residues (pesticides)
Proper processing
Storage conditions
Contamination
9. Chemical Residues Proper use & handling
Time between application and reaping
Residue analysis
10. Processing All processors are licensed by Coffee Industry Board
Annual inspection of works
Powers to revoke license
11. Storage Coffee absorbs anything in its surroundings – must be stored away from chemicals, spices etc.
Store in sealed containers
Low humidity
Low temperature
12. Care in Brewing Coffee Clean equipment with a brush and hot water immediately after use
No detergents or chemicals should be used for cleaning
Do not reheat coffee after brewing . If it becomes cold it should be dumped
13. MYCOTOXINS - Their Impact on Food Safety with Focus on Coffee
14. What are Mycotoxins ? Mycotoxins are metabolic products of
moulds/fungi that infest a wide range of
agricultural commodities, processed food
and animal feed.
15. Major Mycotoxin-Producing Moulds Aspergillus
Fusarium
Penicillium
16. Mycotoxins of Major Interest Aflatoxins – most well known
Ochratoxin
Fumonisin
Zearlenone
Patulin
17. Food & Commodities Commonly Affected Corn & corn products
Oats
Barley
Wheat
Peanuts
18. Food & Commodities Commonly Affected Cereals
Coffee
Dried vine fruits
Wine and beer
Processed pork and fish
19. Mould Infested Corn Mould Infested CornMould Infested Corn
20. Other Affected Animal Products Kidney
Liver
Blood
Human blood samples
21. Where Are Mycotoxins Found Tropical regions
Temperate regions
22. Health Problems Caused by Mycotoxins Cancers – (in many different areas of the body)
Kidney Disorder
Liver Damage
Reproduction Disorder
Respiratory Disorder
Birth Abnormalities
Heart Disease
23. Growth Suppression in turkey poult (right)
24. Livers from guinea pigs given increasing doses of aflatoxin
25. Enlarged uterus in mouse (left) injected with zearalenone
26. Tumor development in liver of trout due to mycotoxin in diet Control
27. Regulations Governing Mycotoxins Monitoring testing at port of entry
Many countries have legislated maximum allowable limits
Allowable limits vary from country to country and is mycotoxin specific.
28. Some Examples of Limits for OTA in Coffee Italy 4 ppb
Spain 4 ppb
Finland 5 ppb
Germany 3 ppb
4 ppb is equivalent to a small teaspoon of OTA spread uniformly over 1000 tonnes of coffee
29. Epidemics Caused by Mycotoxins Balkan Endemic Nephropathy
(Yugoslavia, Romania, Bulgaria)
Cancers of the kidney
12% of population affected
100 % fatality over 2-10 yrs. after diagnosis
Alimentary Toxic Aleukia ( Russia, WWII)
Ergotism (Middle Ages)
30. What Makes Mycotoxins in Coffee of Concern OTA is carcinogenic
Contaminated coffee can contribute from 2.5%-25% of tolerable daily OTA intake from food & beverage (3-4 cups or 25g/day)
The coffee industry (internationally) is instituting limits & testing
Cut off level for OTA in coffee is 2-4 ppb
31. Research Findings OTA has a half –life of 20-50 days in human blood
OTA is not destroyed by the roasting and brewing process
Coffee can contribute up to 25 % of OTA intake
32. Our Response Keep informed on development
Set up testing facility
Conduct survey of OTA in local coffee
Monitor all coffee being marketed
Identify Critical Control Points (CCP)
33. Findings of Local Industry Levels of OTA encountered in Jamaican coffee 1- 5.2 ppb
Most of the local coffee tested have levels well below the 4 ppb limit
34. SUMMARY Mycotoxins are an emerging threat to food safety
There is great need for further research to illustrate the health risks caused by mycotoxins
Major health risks are cancers and damage to the kidney, liver,reproductive system, immune system, respiratory tract
Jamaican coffee have levels below the maximum allowable limit
35. SUMMARY Good Agricultural Practices (GAP) & Good Manufacturing Practices (GMP) must be encouraged
Identify Critical Control Points (CCP) in all food operations
Institute testing
Foster awareness in general public
