Produce traceability makes it possible to track produce from its point of origin to a retail location where it is purchased by consumers. Produce traceability is an important link in protecting public health since it allows health agencies to more quickly and accurately identify the source of contaminated fruit or vegetables believed to be the cause of an outbreak of foodborne illness, remove them from the marketplace, and communicate to the supply chain. Since many fruits and vegetables are eaten raw, the produce industry‚ from farmer to retailer, works diligently to protect these foods from contamination. Despite their best efforts, foreign matter can occasionally contaminate produce in the field or orchard, in packing or processing, in transit or storage. Controlled cold chains are frequently used. Because traceability systems can provide information on the source, location, movement and storage conditions of produce, they also allow growers, packers, processors and distributors to identify factors affecting quality and delivery. Beginning in 2008, an industry-led effort to enhance traceability throughout the entire produce supply chain was launched as the Produce Traceability Initiative.
Trends in outbreaks of produce-related illness An analysis of 3,500 food-poisoning outbreaks between 1990 and 2003 found that contaminated produce was responsible for the greatest number of individual foodborne illnesses. The study, by the Center for Science in the Public Interest, found that produce caused 428 outbreaks and 23,857 cases of illness. Authorities note that several factors have contributed to the rise in outbreaks:
Great consumption of fresh produce, especially cut fruits and vegetables. Wider distribution. Improved electronic reporting of outbreaks. An aging population more susceptible to foodborne illness. Unlike meat, which can be rid of bacteria through proper cooking, fresh produce is often meant to be consumed raw.
The U.S. Food and Drug Administration noted in 2007 that fruit and vegetable-related outbreaks of food poisoning are on the rise and had struck in spinach, tomatoes, lettuce and cantaloupes. The agency urged fruit and vegetable processors to adopt food safety plans similar to those in the meat industry. An outbreak of Salmonella Saintpaul in 2008 was characterized by the US Center for Disease Control as the largest foodborne outbreak in a decade. Some 1304 infected persons were identified in 43 states, at least 252 were hospitalized and two deaths were possibly linked to the outbreak. CDC noted that the trace back of fresh produce, such as tomatoes, through the supply chain could be very difficult and labor-intensive. Ironically, the carrier item was ultimately determined to be jalapeño peppers, not tomatoes.
Benefits Tracing of an item through various stages of production, manufacturing, processing, handling, transportation, sales and consumption is a widespread practice in today's world. Manufacturers may require purchasers to register ownership of a product to facilitate possible future recall for safety reasons or warranty fulfillment. The Post Office and package delivery companies make widespread use of tracking packages from pickup to delivery, even to destinations on the other side of the world.Some often-recognized benefits of traceability include:
Ability to determine the origin of a product, ingredient or component. Simplifies problem-solving in event of defective or contaminated product, ingredient or component. Allows issues to be more quickly identified, contained and resolved. Limits losses and lowers costs. Protects public health and safety. Builds trust and confidence in affected products, businesses or systems. Verifies that produce is locally grown. Improves operating efficiencies for growers, packers and shippers.
Voluntary industry initiatives In 1930, produce industry leaders sponsored legislation to require an internal trail of accounting between buyers and sellers along the entire produce marketing chain. This law, the Perishable Agricultural Commodities Act (PACA) of 1930, set the foundation for basic traceability. More recently, the Bioterrorism Act of 2002 required food companies to keep records that could be traced in the produce supply chain (i.e.one step up and one step back). Based on these records, many organizations in the fresh produce distribution chain have long maintained the ability to trace products inside their enterprise. In simple terms, they know where they got it and where they sent it, but with products that may move through multiple parties who may transform or comingle them, trying to connect many links quickly in time of crisis is a challenge. Some 30 years ago, manufacturers and retailers created an organization called GS1 to improve the efficiency of the distribution of food and consumer goods to supermarkets. One of its many programs was to develop the now-familiar bar code on products that can be scanned at checkout by retailers. GS1‚international standards will provide the foundation for the PTI. Multiple shippers, distributors and retailers in the produce industry have endorsed the Produce Traceability Initiative (PTI) to encourage adoption of whole chain traceability. The initiative's sponsor associations include United Fresh Produce Association (United Fresh), Canadian Produce Marketing Association (CPMA) and Produce Marketing Association (PMA). Both internal and external traceability programs are needed in order to effectively track and trace product up and down the supply chain, achieving whole-chain traceability. At present, most companies have internal traceability programs but not external traceability. The PTI outlines a six-step course of action to achieve chain-wide adoption of electronic traceability of every case produce by the year 2012. Meanwhile, companies are putting into operation technologies that will support the PTI.
