About Chinese Academy of Inspection and Quarantine

Chinese Academy of Inspection and Quarantine

The Chinese Academy of Inspection and Quarantine, known by the acronym CAIQ, is a national public research institute based in Beijing that develops the science and technology used in inspection and quarantine work in China. Inspection and quarantine is the technical system that stands behind border and market controls: it is how imported and exported food, plants, animals and other commodities are tested for pests, diseases, chemical residues and other hazards before they are allowed to move. CAIQ is the research arm of that system. It is affiliated to the State Administration for Market Regulation, and the Nature Index lists it under that administration, with its Institute of Food Safety recorded as an affiliated institution in its own right. Because its work supports regulation rather than replacing it, the academy is best understood as a scientific and technical support institution: it develops methods, reference materials and evidence that inspectors, laboratories and policymakers elsewhere in the system then use.

Origins in two earlier institutes

CAIQ was established by consolidating two earlier organisations with long histories of their own. The first was the Plant Quarantine Institute of the Ministry of Agriculture, founded in 1954, which brought decades of experience in the study of plant pests and diseases and the quarantine measures used to stop them spreading with traded plants and plant products. The second was the China Import and Export Commodity Inspection Technology Institute, founded in 1979, which represented the commodity-inspection side of the system, concerned with the testing of traded goods. Bringing the two together created a single academy spanning both the biological side of quarantine — pests, diseases and invasive organisms — and the analytical side of commodity inspection, in which chemical and physical testing establishes what a product contains and whether it meets requirements. That dual inheritance still shapes the academy's structure and research remit, which ranges from organism identification to advanced instrumental analysis.

Mission and role in government

The academy's stated mission is to conduct research on the applied science of inspection and quarantine, together with basic research, high-technology research and soft-science research, with a focus on solving general and comprehensive problems and the emergent and pivotal issues that arise in the administration of inspection and quarantine. In practical terms, that means CAIQ works on the problems that are too large, too urgent or too technically difficult for individual inspection posts to solve alone: a new pest appearing in traded goods, a contaminant that existing methods cannot detect reliably, or a sudden food-safety incident requiring a validated test at short notice. The academy provides technical support for central-government policymaking on inspection and quarantine, and it has historically provided technical assistance to the law-enforcement work of the former General Administration of Quality Supervision, Inspection and Quarantine, known as AQSIQ. Its research therefore feeds directly into standards, methods and decisions applied across China's ports and markets.

Structure, staff and laboratories

CAIQ is a large organisation by research-institute standards. Published profiles of the academy describe it as consisting of eight institutes and seven technical support centres, overseeing eleven state key laboratories and employing about 1,000 staff, including around 400 researchers. That structure reflects the breadth of the field: inspection and quarantine covers food, plants, animals, industrial products and human health at borders, and each area requires its own specialists, laboratories and reference collections. The subordinate units recorded for the academy include an Institute of Food Safety, an Institute of Equipment Technology whose researchers work on instruments and treatment facilities, and an Agro-Product Safety Research Center. The academy's laboratories operate advanced analytical platforms, including liquid and gas chromatography and mass spectrometry systems used for method development, and its researchers publish in fields including chemistry and the physical sciences, as its Nature Index profile shows.

Food safety research

Food safety is one of the academy's most visible research areas, centred on its Institute of Food Safety, known as the FSI. The institute has a team of more than forty scientists and manages the AQSIQ Key Laboratory of Food Safety, working as an import and export food inspection and quarantine reference laboratory. Its research and method development cover chemical residues, heavy metals and other contaminants in food, with the goal of producing testing methods that can be adopted for routine use across the inspection network. One documented line of work, led by Professor Feng Zhang, used advanced chromatography — including supercritical fluid chromatography systems — to develop simpler and more effective methods for analysing foodstuffs, work undertaken within a key special research project of China's Thirteenth Five-Year Plan period. Methods developed in this way are transferred to other departments within CAIQ that manage routine testing of import and export foodstuffs across China, illustrating the academy's role as a method developer for the whole system rather than only a testing laboratory in its own right.

Plant and animal quarantine

The quarantine side of the academy's work descends directly from the Plant Quarantine Institute founded in 1954. Plant quarantine research deals with the identification of pests and pathogens in traded plants, seeds and produce, the assessment of the risk they pose, and the treatments used to eliminate them. Researchers in this area at CAIQ have worked, for example, on phytosanitary treatments for fresh products, including alternatives to the fumigant methyl bromide, temperature treatments for fruit and vegetables, and monitoring systems for fumigant gases in port warehouses. Animal quarantine and health quarantine — covering disease risks moving with animals, travellers and goods — are also part of the academy's recorded research remit, alongside food safety, plant quarantine and instrument analysis. This breadth matters because the same consignment can raise several kinds of question at once, and the academy is organised to answer them within one institution.

Agro-product safety, authenticity and tracing

A further specialism is the safety and authenticity of agricultural products. The academy's Agro-Product Safety Research Center works on detection, monitoring and tracing technology for agro-product quality and safety, including the identification of food and agricultural products by species, functional components and quality characteristics. Its researchers apply genomics and high-throughput DNA sequencing to problems such as food adulteration, developing DNA-based methods that can establish what a product actually contains — for example, rapid detection methods for particular fruit components that pose an allergy risk, and droplet digital PCR approaches for identifying and quantifying ingredients. Food adulteration is both a safety issue and a trade issue, since substituted or mislabelled products undermine consumer trust and fair commerce, and the academy's work gives regulators molecular tools to detect it. Traceability research complements this by following products through supply chains, so that when a problem is found its source can be located.

Instruments, standards and technical support

Inspection depends on instruments and standardised methods as much as on scientific insight, and CAIQ's remit explicitly includes instrument analysis. Its equipment-technology researchers work on the facilities used in quarantine treatment and detection, such as fumigation monitoring and phytosanitary treatment systems, while its analytical laboratories develop and validate the test methods that become standard practice. Because the academy oversees key laboratories and reference functions, its validations carry weight beyond its own walls: a method proven at CAIQ can be adopted by inspection laboratories across the country. The academy also functions as a technical support centre for the regulatory system in the broader sense, supplying expertise for policymaking, enforcement and emergency response when new hazards emerge. This combination — research institute, method developer, reference laboratory and policy adviser — is characteristic of China's national technical institutions, and CAIQ is the principal example in the inspection and quarantine field.

International cooperation

The academy's work has an international dimension, because inspection and quarantine is inherently about trade between countries. In 2013 CAIQ signed a memorandum of understanding with the National Center for Food Protection and Defense at the University of Minnesota, a United States Department of Homeland Security centre based in the university's College of Veterinary Medicine. The agreement, signed by University President Eric Kaler and CAIQ Director General Li Xinshi, covered collaboration on food safety, food protection and food defence — the prevention of intentional contamination of the food supply, whether for economic fraud or terrorism. The two sides planned to begin with topics such as economically motivated adulteration, or food fraud, and risk assessment in the food system, with professional training as a significant component. The partnership illustrates how the academy's expertise in detecting adulteration and assessing food-system risk is recognised and used internationally.

Why the academy matters

CAIQ matters because so much of food safety and biosecurity depends on unglamorous technical capacity: validated tests, reference materials, trained specialists and laboratories able to respond when a new pest, contaminant or fraud appears. China's trade volumes make that capacity especially important, and the academy concentrates it in one national institution with roots reaching back to 1954. Its combination of plant and animal quarantine, food safety, agro-product tracing and instrument research, its network of institutes, centres and key laboratories, and its direct line into central-government policymaking make it a central part of the country's inspection and quarantine system, and a significant research publisher in analytical and food-safety science.
