2. Aspects of Food Safety: Developments &
Global Trends
Part – I
• Food Quality & Food Safety Requirements
Aspects
• WTO, Codex and Harmonization of
Standards
Part –II
• Residues of Toxic Contaminants

 Solid or liquid
 Digested when ingested
 Assimilated in the body
 Performs various functions in the body
What is Food ?
 Anything that is eaten or ingested and includes :
Beverages like water, Additives like spices

9. Perception of Quality Food ?
Regulator
Nutritious, healthy, safe
functional, un-adulterated,
hygienic
 Food quality is perceived differently by consumer and
the regulator
 Stringent quality norms for international trade
Consumer
Freshness, aroma, taste,
appearance, free from foreign
particles and insect
infestation

10. Food Safety

11.  Safe food is the one without:
 Microbial contamination
 Mycotoxins
 Environmental contamination
 Residual Agrochemicals
 Residual Antibiotics/Veterinary Drugs
 Unsafe Gene Modification
 Banned Chemicals
 Adulteration
 Definition based on impurities : minor or major

18. Food Safety Laws

19.  Consumer confidence in food
 Greater assurance
 Transparency
 Traceability
Requirements of Food Safety Laws
All the above to be reflected in food
laws
Food laws should be universal with
harmonized standards and norms

20. Food Safety: Development & Trends
 All the developments demand for food safety as a
criteria for food quality for global food trade
 The trends are clear for harmonization of standards and
compliance of SPS norms
Development Resulting Trend
WTO
Codex
SPS
PS
• Undisputed platform for resolving global food
trade issues
• Harmonization of food quality Standards
• Mechanism & systems to ensure food safety
• Systems to streamline the global food trade
between developing and developed countries

21. CODEX
Codex Alimentarious: Definition
Science based
organization
Reference point for food
safety
Focal point for R&D in
food
Independent and
unbiased
Consisting of experts
Multi-disciplinary
An independent international organization serving as the reference
point for food safety consisting of experts from multi-disciplinary areas
of food safety in the world
Codex A set up by WHO & FAO in 1962 has emerged as the focal point
for all food safety issues
What is Codex A? What it consists of?

22. CODEX
Codex Alimentarious: Scope
Food safety
issues
Labelling
Exchange of
information
Facilitation for
compliance of
food safety
Standards & quality
norms
R & D on food
safety
Codex A deals with all aspects of food safety for global food trade
To provide informations: quality, standards, R & D, etc.
A reference for 169 members for disputes of food trade
What it deals with? What is its purpose?

23. CODEX
Codex Alimentarious: Dimensions
Harmonization of
standards
Information provider
Resolution of disputes
Level-up
approach
Prioritization of R & D
areas for food safety
Scientific basis for
quality standards
 Codex A has several facets, as an inter-governmental
statutory body to ensure food safety for all !

24. Sanitary and Phytosanitary Measures
Agreement (SPS)
 Protects human, animal and plant health
 Based upon scientific principle involving risk
assessment studies
 Covers all aspects of :
 Testing
 Inspection
 Certification
 Approvals
 Packaging and Labelling
 All aspects are directly related to food safety

25. SPS Agreement : Based on 7 Principles
 National Sovereignty : Countries can use own risk standards
 Harmonisation : Reach a common measurement
 Equivalence : Acceptance of SPS measures of
another countries
 Science based measures : Include risk assessment studies
 Regionalisation : Allow Exports from disease free area
 Transparency : With respect to SPS measures if
differ in internationally recognised
standards
 Dispute resolution : Provides mechanism for resolving
disputes through scientific justification
 Leading multilateral agreement affecting the international
food trade ; Essential for food trade !

26. Food Safety Issues :
Developed Vs Developing World

27. Food Consumption Pattern ?
• Mostly fresh food
• Additives and chemicals used for
preservation and aesthetics
• Mostly Processed Food
• Additives and chemicals used for
preservation
• Food Safety is not a major concern
• Less concern about microbial,
chemical residues
• Food safety norms: Flexible
• Food Safety is major issue
• High concern about microbial,
chemical residues
• Food safety norms: Stringent
Developing
Countries

 A perceptible divide : trade barriers is an issue!

28. Issues Related to Food : Status ?
• PrimarySecurity

 A distinct division between the developed and developing
countries on various issues related to food and food trade !
 Immediate effect becomes a safety issue in developing
countries the long term effect concerns developed countries

30. • Institutional Co-ordination
Food Safety: Key issues for India
 Focus to create: Awareness for food safety issues; R & D infrastructure;
capability-building in monitoring; human resources development and
opportunities for adoption of state-of-the-art technologies
• Awareness of safety & quality control amongst stake-
holders in organized & unorganized sectors
• Incidences of Food-borne diseases
• Emergence of newer vibrant pathogens
• Quality of imported food products
• R&D focus & outreach
• Responsive monitoring system
• Technical skills & equipment facilities
• Introduction of variety of GM foods

37. What are we trying to say ?
 Food safety issues are complex in several
ways
 A divide exists between the producers and
consumers at international level
 Producers (Developed Countries) of bulk food
import functional food, producers (Developing
Countries) of functional food do of bulk
 Opportunities exist for all but the onus for
dealing with the challenges also lies on all !`
