Safe produce supply chain [1]: Standardize from the source

Building the growing zone

At 10 in the morning, dozens of workers move briskly through the fields at Chau Pha Agricultural Production and Services Cooperative, harvesting vegetables under the open sun. Nguyen Viet Tu, the cooperative's director, said the organization has around 60 members farming more than 55 hectares, producing roughly 10 tonnes of vegetables daily. Products are distributed to retail chains, including Bach Hoa Xanh and Eon, as well as dedicated safe-produce outlets.

The workflow is tightly sequenced. Harvesting begins around 10 a.m., initial processing starts at 2 p.m., and by 6 p.m., the produce is loaded and moving toward distribution points, a schedule designed to preserve freshness by the time it reaches the consumer.

Tu said maintaining that rhythm required the cooperative to gradually reshape how its members work, from keeping production logs to consistently following technical protocols, changes that did not come overnight.

At Tuan Ngoc Agricultural Cooperative, quality assurance begins at an even more granular level. Director Lam Ngoc Tuan said the cooperative's hydroponic model uses sensor networks to continuously track environmental variables, temperature, humidity, and nutrient levels, displayed in real time on mobile devices. This allows growers to monitor plant conditions at any time and make prompt adjustments when conditions shift. The approach reduces reliance on individual judgment and instinct, limits risk exposure, and maintains consistent product quality across batches.

That kind of systematic discipline is increasingly common among operations that have transitioned to certified production. Nguyen Kieu Oanh, director of Mekong Delta Company, said her business supplies 8 to 10 tonnes of vegetables and produce daily across more than 20 product lines to various distribution systems.

Supply comes from two sources: growing zones the company directly manages and contracted smallholder farms. About half of total volume comes from company-controlled land certified under VietGAP standards; the rest comes from the partner network.

Keeping quality uniform across both sources requires layered oversight. Beyond coaching farmers on cultivation techniques, the company conducts both scheduled and random sampling of every shipment before it enters the market, tracking pesticide residue levels, microbial counts, and other indicators to catch problems early. A traceability system runs in parallel, logging the full production journey from seeding through harvest. "We do not only check at the end, we control from the very beginning. If something goes wrong, we can trace it back to the specific batch and the specific producer," Oanh said.

The market problem

Producing to standard is one challenge. Finding a market that rewards it is another. Tu said consumers still struggle to distinguish certified safe vegetables from ordinary produce, which means the competitive advantage that comes with compliance rarely shows up in the price. Certified producers must compete head-to-head on price with conventional suppliers, despite carrying significantly higher production costs.

That gap points to a systemic weakness in the supply chain that goes beyond farming practices. The problem is the absence of a sufficiently powerful recognition mechanism, one that would allow the market to see and value the difference. Without standardized, widely disseminated information, the efforts of individual cooperatives and companies remain fragmented, unable to accumulate into a genuine competitive edge.

Dao Ha Trung, chairman of the Ho Chi Minh City High-Tech Association, argued that programs such as the "responsible green tick" certification are moving in the right direction by establishing a multi-party verification framework that involves regulators and distributors. When multiple credible parties endorse the same product, that endorsement functions less like a label and more like a passport, one that elevates perceived value and broadens market access. The problem, he noted, is that no such mechanism has been standardized at scale. Each distribution system applies its own criteria, forcing producers to comply with multiple overlapping requirements every time they try to expand their customer base.

From a regulatory standpoint, Nguyen Nguyen Phuong, deputy director of the Ho Chi Minh City Department of Industry and Trade, pointed to the lack of synchronization across the chain as the most significant current constraint. "Controlling quality at isolated links in the chain is not enough to build something sustainable," he said.

That observation helps explain why, even as the volume of certified production grows, safe agricultural products have yet to carve out a clear and durable market advantage. Without a shared recognition framework strong enough to set certified goods apart, compliant products continue to blend into the general market. Closing that gap, observers argue, requires establishing a common anchor for the entire chain, one in which standards are unified, information is transparent, and all players can connect more efficiently.
