Introduction

• Foodborne diseases (FBDs) is a significant public health problem with major economic and social effects .

• Cases of FBDs occur daily in all countries, from the most to the least developed.

• Unsafe food causes many acute and life-long diseases, ranging from diarrhoeal diseases to various forms of cancer.

Page 4: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

• WHO estimates that foodborne and waterborne diarrhoeal diseases taken together kill about 1.9 million people annually, 1.6 million of them children under (5) years of age. (WHO 2004).

• As well as the significance of FBDs in terms of morbidity and mortality, these illnesses have enormous implications forprimary industryfood manufacturing retail industry and for trade.

Definition of Forborne Diseases

WHO• FBDs are the result of ingestion of foodstuffs

contaminated with microorganisms or chemicals.

• The contamination of food may occur at any stage in the process from food production to consumption (“farm to fork”) and can result from environmental contamination, including pollution of water, soil or air.

Page 6: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

CDC• FBDs are caused by consuming contaminated

foods or beverages. Many different diseases causing microbes, or pathogens, can contaminate foods, so there are many different foodborne infections.

• In addition, poisonous chemicals, or other harmful substances can cause FBDs if they are present in food.

Page 7: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

• More than 250 different FBDs have been described. Most of these diseases are infections, caused by a variety of bacteria, viruses, and parasites.

• NO one syndrome for FBDs. However, the microbe or toxin enters the body through the gastrointestinal tract, and often causes the first symptoms; nausea, vomiting, abdominal cramps and diarrhea are common symptoms in many FBDs.

Page 8: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

• Infections can spread through contaminated food, drinking water, swimming water, and from toddler to toddler at a day care center.

• Measures to control / reduce other cases from occurring could range from removing contaminated food from stores, chlorinating a swimming pool, or closing a child day care center.

Food Services Situation in Dubai

Page 10: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

• Although it is currently impossible to assess the cost and extent of foodborne diseases in UAE, (FBDs) still constitute public health problem.

• Surveillance and epidemiology are important in understanding and controlling food borne pathogens and their patterns of transmission.

Obstacles and barriers

• Ununified case definition

• Most cases are not reported, the true dimension of the problem is unknown.

• Methods and mechanism of reporting are not adequate in addition to feedback.

Page 12: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

Most reported foodborne diseases are sporadic rather than associated with well-defined outbreaks. This may be more frequently due to non-hygienic food handling practices

Conclusion • Although the trends of foodborne diseases

showed a clear drop in the last (5) years due to effective preventive measures, still there is possibility of increasing, this is explained by…Accurate and adequate data is not always

available. Unified reporting system based on policy and

guideline is not always available.

Accordingly we recommend the following

Page 26: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

Recommendations

1. Develop best practice guidelines for surveillance, investigation and control of foodborne diseases.

2. Establishment of a national laboratory network to identify gaps in laboratory diagnosis / investigation of foodborne disease, including specimen collection, submission, and make recommendations for improved detection.

Page 27: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

3. Updating the notification list to include the emerging and re emerging pathogens.

4. Develop and implement a National Foodborne Disease Outbreak Surveillance System.

Page 28: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

5. Plan and conduct of appropriate research to support these plans.

6. Uniform food safety legislation and standards at the national level.

Page 29: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

7. Increase public and industry awareness on foodborne diseases

Food contamination can occur at any stage from farm to table. Everyone on the food delivery chain must employ measures to keep food safe.

Farmer, processor, vendor and consumer education is just as vital to prevent disease outbreaks.

Educating school children on safe food handling behaviors is key to preventing foodborne diseases today and in the future.

Page 30: Trends of Foodborne Diseases at Dubai 2006 – 2010 Dr. Fatma Al Attar M.D,ABFM,MRCGP Head of Preventive Services Section.

• Preventing animal infections at the farm level can reduce foodborne diseases.

• Collaboration with concerned sectors (Ministry of; agriculture, education, water and environment, etc….

5 Keys to Food SafetyKeep Clean Separate

raw food from Ready-to-eat

Cook foodthoroughly

Keep food at safe temperature

Use safe water and raw materials

In addition to ongoing Training in Quality Assurance across all food sectors.
