Food is transported over longer distances, across continents The supply chain has become longer and more fragmented, so consumers have become more disconnected from the food source Food gets wasted/lost at every stage of the chain The longer the chain, the more the chances for overall food waste  07/07/2024 Major challenges in Food Supply Chains Traceability in the food supply chain One of the biggest challenges with implementing Traceability in the food supply chain refers - ability effective traceability systems in food supply chains to track the movement of food products from their Because of the complexity of the supply chains origin to the consumer, ensuring transparency and Food products can pass through multiple intermediaries, accountability throughout the entire process including producers, processors, distributors, and retailers, before reaching the end consumer But, common challenge in food supply chains related What is a common challenge in food supply chains to traceability - Lack of transparency related to traceability? So, role of government regulations in food supply Lack of transparency chains - Ensuring safety and quality standards Consumers bear the cost of postharvest losses Point Farmer Middlemen I Middlemen II Consumers Invest 10000.00 for 100 kg 11,000.00 Rs 12,800.00 15,000.00 for 60 kg How to ensure safety Waste/ damage 0 20% = 80 kg left 20 % (initial) = 60 kg left 2 kg waste Domestic waste and minimize waste Selling @ 110.00 Rs @ 160.00 Rs @250.00 Rs 259.00 Rs Profit 110.00 Rs x 160.00 x 80 = 250.00 x 60 = 100 = 12,800.00  15,000.00  We will study some of the following ….. 11000.00 Rs 1,800.00 Rs 2,200.00 Rs  1000.00 Rs If we buy 110.00 Rs 160.00 Rs 250.00 259.00 Rs @ this point ~145 % ~227 % ~235%  07/07/2024 How to ensure safety and minimize waste How to ensure safety and minimize waste 1.

A supply chain management is an integrated network including people, organizations, information, activities and resources. Logistic management of food supply chains QC, QA, TQM & Role of quality control circles Quality control (QC) is a procedure or set of procedures intended to ensure that the product or service adheres to a defined set of quality criteria or meets the requirements of the client or customer Quality assurance (QA) is a set of activities for ensuring quality in the processes by which products are developed. It is a proactive (practical/positive) process It aims to prevent defects by concentrating on the process used to make the product. QC is similar to, but not identical with, quality assurance (QA).  07/07/2024 QC, QA, TQM & Role of quality control circles Total Quality Management (TQM) is a continuous improvement approach to doing business without any failure TQM is a comprehensive management system and it, Focuses on meeting customer’s needs by providing quality services at a cost that provides value to customers Is driven by the quest (mission) for continuous improvement in all operations Recognizes that everyone in the organization has owners/ customers who are either internal or external Views an organization as an internal system with a common aim rather than as individual departments acting to maximize their performances Focuses on the way tasks are accomplished rather than simply what tasks are accomplished Emphasizes teamwork and a high level of participation by all employees GAP, GVP, GMP, GHP and other related practices GAP, GVP, GMP, GHP and other related practices Good pharmacovigilance practices (GVPs) are GVP is a set of voluntary guidelines developed by producer guidelines for pharmaceutical companies to follow organizations, food industry, NGOs, and government for to help prevent harm to humans caused by adverse produce farmers to produce foods and crops with reduced risk of microbial contamination, that is related to foodborne drug reactions (i.e., ADRs) from approved illnesses on their farms. pharmaceutical drugs.

Food Safety Food safety Assurance that food will not cause an adverse health Food safety refers to routines in the preparation, handling effect for the consumer when it is prepared and/or and storage of food meant to prevent foodborne illness and consumed in accordance with its intended use injury. From farm to factory to fork, food products may Food Safety is a way of making sure that food is encounter any number of health hazards during their produced in ways that prevent food-borne illnesses. journey through the supply chain. Therefore food safety also simply means “meeting customer’s food safety requirements”.  07/07/2024 Organic food certification Organic food certification ORGANIC PRODUCTS Organic certification is a requirement to Organic agriculture is a sustainable form of demonstrate a product or operation has met these agriculture, for both ecological and economic legal standards. reasons.
