Supply Chain
Food produced for trade requires that such food meets certain quality and safety requirementsOne must be able to trace back the food from the place of production – through the supply chainSupply chain- the entire set of inputs, production, distribution, marketing and final delivery of a product to consumersIs also called agro-chain, product chain, value chain, commodity chain, agri-food system, etc.

Supply chain management – is any form of cooperation between stakeholders in the supply chainIn agriculture, some supply chains are loose and unstable over time while others are stable and well managedUnstable: Farmers selling produce to hotelsStable: Export of bananas to the UK.
Supply chain management is important in the provision of safe food.The responsibility for the supply of safe food is shared along the entire food supply chain by all stakeholders;
Input supplyProductionHarvestingProcessingTrade
Roles and Responsibilities
Public sector- development of official standards, provision of incentives, research, extension, regulations, and enforcement, information etc.Private sector – responsibility for investment, management and cost to ensure food production, post-harvest treatment, processing, distribution based on food safety standards, etc.
Drivers for Supply Chain Management
Variations in quality and quantityIncreasing consumer attention to safety and protection of the environmentShelf life constraintsVariation in the speed/rate of production

Need for National Food Control Systems
Increasing burden of foodborne illness and new and emerging foodborne hazards
Rapidly changing technologies in food production, processing and marketing
Greater focus on consumer protection with science-based risk assessments
Need for National Food Control Systems
International food trade and need for harmonization of food safety and quality standards
Food trade is disrupted by frequent disputes over food safety and quality requirements
Meet obligations of international trade agreements such as WTO
Need for National Food Control Systems
Changes in lifestyles, including rapid urbanization
Unprecedented consumer interest in the way food is produced, processed and marketed
Increasing consumer demand for better information of food safety and quality issues
Food Quality
Food quality is most typically associated with use characteristicsAll intrinsic attributes that influences a product’s value to the consumerMay be positive attributes associated with origin, nutritive, organoleptic(colour, flavour, texture), processing method of the food or other properties of values to usersAlso includes negative attributes such as spoilage, contamination with filth, discoloration, off-odours
Food Safety
All those hazards, whether chronic or acute, that may make food injurious to the health of the consumerThe absence of any risk of harm from foodInvolves the practical process of ensuring that food is fit to eat-assurance of safetyFood safety is the most important quality factorIs not negotiable
Food control defined“a mandatory regulatory activity of enforcement by national or local authorities to provide consumer protection and ensure that all foods during production, handling, storage, processing, and distribution are safe, wholesome and fit for human consumption; conform to safety and quality requirements; and are honestly and accurately labelled as prescribed by law”.
Critical Food safety Issues
Many problems with food safety have increased public anxiety that modern farming systems, food processing and marketing do not provide adequate safeguards for public healthWhat are the food hazards of concern◦ Microbiological hazards◦ Pesticide residues◦ Misuse of food additives◦ Chemical contaminants, including biological toxins
What are the food hazards of concern
◦ Adulteration◦ Genetically modified organisms (GMOs)◦ Allergens◦ Veterinary drug residues◦ Growth promoting hormones
Consumers must be protected from food hazards along the entire food chain; the farm-to-table continuum
What is required◦ An integrated approach ◦ Control systems must address all stages in the food
chain◦ Preventive and educational strategies
Effective enforcement of legal requirementsTraining and educationCommunity outreach programmesPromotion of voluntary compliancePreventive strategies such as HACCP implementation
Global Considerations
International trade◦ International trade in fresh and processed foods will
continue to increase◦ Access to export markets will depend on capacity to
meet requirements of importing countries◦ Need to build trust and confidence of importers and
consumers in integrity of our food systems
SPS and TBT Agreements
SPS-Sanitary and PhytosanitaryTBT- Technical Barriers to Trade
◦ Came into being after the establishment of the WTO◦ Agreements are important for requirements for
food protection at the national level, and rules under which food is traded internationally
SPS Agreement
◦ Confirms the right of WTO member countries to apply measures to protect human, animal and plant life and health
◦ Covers lawsregulationsdecreestesting inspectioncertification and approval procedurespackaging labelling requirements
SPS Agreement
◦ Apply only those measures for protection based on scientific principles and only to the extent necessary◦ Not in a disguised manner to restrict international
trade◦ Use of international standards/guidelines- Codex
standards (not product standards) used as a benchmark◦ Need to harmonize national food standards with
Codex standards
TBT Agreement
◦ Requires that technical regulations on traditional quality factors, fraudulent practices, packaging, labelling etc imposed by countries will not be more restrictive on imported products than they are on products produced domestically. ◦ Also encourages use of international standards
What is a standard
“A standard is a document which sets out rules that control how people develop and manage materials, products, services, technologies, processes and systems”.
“Document, established by consensus and approved by a recognised body, that provides for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context”.
“An acknowledged measure of comparison for quantitative or qualitative value; a criterion”.
What is food“Food means any substance, whether processed, semi-processed or raw, which is intended for human consumption, and includes drinks, chewing gum and any substance which has been used in the manufacture, preparation or treatment of ‘food’ but does not include cosmetics or tobacco or substances used only as drugs.”
What are food standards“Food standards concern themselves with the quality, identity, composition, safety, labelling, advertising, presentation or other aspects of the food and its preparation”
Available standards◦ International◦ Regional◦ National◦ Industry◦ Company
Other forms of standards◦ Technical specification-document that prescribes
technical requirements to be fulfilled by a product, process or service(may be a standard, part of a standard or independent)
Other forms of standards
◦ Code of Practice –document that recommends practices or procedures for the design, manufacture, installation, maintenance or utilisation of equipment, structure or products
e.g. Good Agricultural Practices (GAPs)
◦ Regulation-Document providing binding legislative rules, that is adopted by authority
Technical regulation-regulation that provides technical requirements, either directly or by referring to or incorporating the content of a standard, technical specification or code of practice
Types of Food standards
Standard of identity◦ Standards of identity define what a given food product is,
its name, and the ingredients that must be used, or may be used in the manufacture of the food.
◦ Food standards ensure that consumers get what they expect when they purchase certain food products.
◦ These food standards prescribe minimum amounts of certain ingredients, such as meat or poultry or milk fat; maximum fat and water contents; methods of processing, cooking and preparation; permit optional safe and suitable ingredients, and/or identify expected or characterizing ingredients.
Standards of Identity
◦ These standards ensure that the basic nature of foods is maintained to meet consumers' expectations no matter where they buy the product.
◦ Without standards of identity, different foods could be sold under the same name and different names could describe the same food.
Standards of quality
◦ Quality standards set quality minimums that must be met or exceeded
◦ Establish specifications for quality requirements
◦ Set minimum specifications for such factors as tenderness, color, and freedom from defects for canned fruits and vegetables.
◦ Such characteristics would not be readily apparent to the purchaser of these foods because of the nature of the foods and the manner in which they are presented to the consumer (inside a can).
Fill-of-container standards
◦ Define how full the container must be and how this is measured
◦ These requirements are particularly important when foods are packed in liquids and sealed in opaque containers.

condensate
What does hygiene mean
◦ Bad food quality!!!!!!!!!
• Incorrect cleaning procedures
• Incorrect production process
• Incorrect “cool chain”
What does hygiene mean
Hygiene deals with preserving healthA hygienic operation presents no risk of illness from the operation carried on thereinFood hygiene is much more than cleanliness; it involves
“all measures necessary to ensure the safety and wholesomeness of food during production, preparation, processing, manufacturing, packaging, storage, distribution, handling and offering for sale or supply to the consumer
What does hygiene mean
Protecting food from risk of contamination; cleaning, disinfection, personal hygiene, trainingPreventing any organisms from multiply to pose a risk to consumers or allow premature spoilage of foodDestroying any harmful bacteria in the food through thorough cooking, processing and other meansRemoving contaminated food

Micro-organisms in food◦ Useful: Fermentation: Lactic acid bacteria, yeast
◦ Spoilage (quality/shelf life)Bacteria, yeast, moulds
◦ Pathogenic (safety/hazards)BacteriaVirusesParasitesToxins (poisons)
Micro-organisms in FoodWhen food is spoiled, the characteristics of the food are changed in such a way that it is no longer acceptable for consumption (not necessarily dangerous)
Micro-organisms in Food
One cannot tell the difference between food contaminated by pathogenic bacteria and safe food
Micro-organisms in FoodBacteria are living organisms In ideal conditions they will grow and multiply◦ Food◦ Temperature (warmth)◦ Time◦ Moisture (water)◦ Oxygen◦ Non-acid environment/foodBacteria multiply by splitting into two – binary fission

What are GAPs
GAPs are sanitary procedures used during crop production, harvesting, packing and distribution to prevent or minimize produce contamination with pathogens
What are the enemies?
◦ Plant pathogens◦ Human and animal pathogens
GAPs guidelines and areas of concern
◦ Water quality◦ Fertilizer use◦ Worker health and hygiene◦ Field and facility sanitation◦ Transportation/distribution issues◦ Traceback and recall
Fertilizer use
◦ Chemical contamination◦ Environmental pollution◦ Use of organic manure/Introduction of pathogens◦ Worker health and safety
Worker health and hygiene
◦ Personal hygiene◦ Hand washing◦ Worker illness◦ Sanitary facilities for workers
Field and facility sanitation
Clean equipment and containers/packagingField sanitationPackhouse sanitationWaste managementPest control
Water quality
◦ Potable water versus raw waterIrrigationWashingIcingCoolingWater for staff facilities/use
What can growers and packers do?
◦ Learn about the risks◦ Find about the enemies◦ Develop a food safety plan◦ Keep records
Transportation/distribution issues
Sanitary vehicles and containersCold chainHandlingTime Operational proceduresCustomer issues
Traceback and recall
◦ The need for traceback and recall◦ Procedures◦ Product identification◦ Identification of possible route of contamination◦ Records and “due diligence”
On-Farm Food Safety Plan
◦ Designate Farm sanitarian-develop, implement, monitor, record
◦ Identify GAPs/GMPs specific to agricultural environment◦ Prepare SOPs for production, harvesting and field
packing activities◦ Develop master sanitation schedule◦ Keep field, facility and equipment sanitation records on
file◦ Document sanitation system is working◦ Continuous training of staff
Remember food quality and safety are not one and the same
While Food Quality is an Option Food Safety is an Entitlement
