British authorities are preparing contingency plans for potential food shortages this summer should the conflict between Iran and its adversaries persist, according to recent media reports. The government has reportedly activated its emergency response framework, known as COBRA, to assess risks arising from prolonged disruption in the Strait of Hormuz, a critical maritime chokepoint for global energy and commodity flows.
Officials are particularly concerned about the potential impact on carbon dioxide (CO₂) supply chains, which are vital for food preservation, packaging, and slaughterhouse operations across the UK. A sustained blockade of the Strait could interrupt liquefied natural gas (LNG) deliveries, thereby affecting ammonia and fertilizer production—processes that generate CO₂ as a byproduct. This, in turn, may reduce the availability of food-grade CO₂ used to extend shelf life in products such as packaged meats, salads, and baked goods.
The scenario under review assumes that if diplomatic efforts fail to secure a lasting ceasefire and the Strait remains blocked, food supply challenges could emerge as early as June. In the most severe projection, CO₂ availability might fall to just 18% of current levels, significantly disrupting industries reliant on the gas for both food processing and beverage carbonation.
Beyond food supply, officials have noted that a CO₂ shortage could also affect medical sectors dependent on dry ice for the temperature-controlled transport of blood samples, vaccines, and organs. However, government representatives have emphasized that these measures are precautionary and that there is no immediate indication of supply disruption.
Industry analysts suggest that even as concerns over shortages exist, many businesses are more immediately attentive to rising costs stemming from energy price volatility and broader inflationary pressures. The UK’s food and drink sector has previously experienced CO₂ supply volatility, most notably during 2021 when a combination of plant outages and increased demand led to temporary shortages affecting poultry and carbonated drinks.
As of mid-April 2026, no official government statement has confirmed the activation of emergency protocols beyond routine contingency planning. The situation remains under review by cross-departmental officials, with updates expected should geopolitical conditions in the Gulf region evolve.
