KOTA KINABALU, Malaysia: South Korea’s renewed struggle with avian influenza is more than a domestic agricultural problem.

It is a reminder of how fragile Asia’s food systems remain in the face of biological shocks, and how quickly a local outbreak can cascade into a regional supply crisis if left unmanaged.

Avian flu outbreaks are not new to East Asia, but each resurgence exposes the same structural vulnerability. Modern food systems are built for efficiency, not resilience.

Poultry production in particular is highly concentrated, industrialised, and dependent on tightly coupled supply chains. When an outbreak spreads across farms, the response is necessarily blunt: mass culling, movement restrictions, and market disruption.

The immediate goal is containment, but the collateral damage is often underestimated.

Poultry remains one of Asia’s most important and accessible protein sources. In many countries it is the cheapest animal protein available, central to daily diets and smallholder livelihoods.

A significant die-off of domesticated fowl, whether through disease or preventive culling, does not merely reduce supply. It pushes prices upward, shifts demand abruptly to alternative proteins, and places strain on already stretched food systems.

The danger lies not only in the loss of chickens and ducks themselves, but in the knock-on effects. Feed supply chains, hatcheries, transport networks, wet markets, and food processors all feel the shock.

In some cases, export bans and import restrictions amplify volatility, creating shortages in countries that are otherwise far removed from the outbreak’s epicentre.

There is also the question of viral evolution. While most avian influenza strains primarily affect birds, the constant circulation of the virus increases the risk of mutation and reassortment.

This raises concerns not just for animal health, but for broader public confidence in food safety. Even when risks to humans remain low, perception alone can devastate demand, as seen repeatedly during past outbreaks.

Asia cannot afford to treat avian flu as a recurring inconvenience. The region’s food security environment is already under pressure from climate change, extreme weather, fertiliser disruptions, and geopolitical tensions.

Biological shocks add another layer of uncertainty, one that does not respect borders or trade agreements.

For ASEAN states, South Korea’s situation should prompt urgent reflection. While ASEAN is not directly responsible for managing outbreaks beyond its borders, it is deeply embedded in regional food trade flows.

Poultry products, feed ingredients, and breeding stock move across Asia with ease. So do pathogens.

The first imperative is information. ASEAN mechanisms must prioritise rapid data-sharing on animal disease outbreaks, not only among veterinary authorities but also across food security, trade, and logistics agencies.

Delayed or fragmented information leads to overreaction in some areas and complacency in others, both of which undermine stability.

Second, ASEAN should review contingency planning for protein supply shocks. Food security discussions often focus on rice, but protein scarcity carries distinct social and political risks.

Governments need clear strategies to manage sudden poultry shortages, including buffer stocks, temporary diversification into alternative proteins, and support for small producers to prevent permanent exits from the sector.

Third, biosecurity standards across the region remain uneven. While wealthier economies may enforce strict farm-level controls, gaps persist in smallholder systems, live animal markets, and cross-border transport.

ASEAN has long discussed harmonisation of sanitary and phytosanitary standards, but outbreaks like this underline the cost of slow implementation.

The question of trade controls is politically sensitive but unavoidable. Should ASEAN consider precautionary measures on poultry imports from affected regions such as South Korea?

Blanket bans can be economically damaging and diplomatically fraught, yet the absence of clear, coordinated guidelines risks uncoordinated national responses that are even more disruptive.

A calibrated approach is needed. Targeted restrictions based on transparent risk assessments, coupled with enhanced inspection and traceability, may offer a middle path.

The goal should not be punishment or isolation, but risk reduction and confidence-building. Equally important is signalling to markets that measures are temporary, science-based, and subject to review.

Finally, ASEAN must think beyond immediate containment and toward long-term resilience. This means investing in regional disease surveillance, supporting research into vaccines and rapid diagnostics, and encouraging more diversified and decentralised food production models. Over-reliance on a narrow set of protein sources is a strategic vulnerability.

South Korea’s avian flu outbreak is not an isolated event. It is part of a pattern that will likely intensify as climate pressures, high-density farming, and global trade intersect. The question is not whether Asia will face similar shocks again, but whether it will be better prepared next time.

Food security is not only about yields and imports. It is about trust, coordination, and the ability to absorb shocks without tipping into crisis.

ASEAN has the institutional tools to act, but outbreaks like this test whether it has the political will to treat biological risks with the same seriousness as economic or strategic ones.

If this warning goes unheeded, the next outbreak may not stop at farms.
