The UK government has been accused of complacency over mounting threats to the country’s food supply chain, as industry leaders warn that disruptions linked to fuel shortages, cyber-attacks, global conflicts and extreme weather could trigger a major national food crisis.
The Cold Chain Federation (CCF), which represents businesses responsible for storing and transporting temperature-sensitive food, medicines and pharmaceutical products across the UK, has called on ministers to make food supply resilience an “immediate national priority”.
Industry figures warned that Britain’s food infrastructure remains dangerously vulnerable to external shocks at a time of increasing geopolitical instability and climate-related disruption. Concerns have intensified following recent tensions in the Middle East, the continued disruption of global fertiliser supplies, and growing fears over cyber threats targeting critical logistics systems.
Phil Pluck, chief executive of the CCF, said the risks facing Britain’s food network are now greater than at any point in recent decades.
“The potential for a major food crisis is as great now as it ever was,” Pluck warned. “We are at the mercy of so many different factors now, which are becoming increasingly dangerous to food supply in this country.”
UK Food Supply Chain Faces Multiple Risks
Britain relies heavily on imported food, with more than one-third of all food supplies entering the country from overseas markets. Much of this trade passes through just four major ports, creating significant vulnerability if shipping routes or border operations are disrupted.
The CCF warned that international conflicts, delays at UK borders, fuel shortages or failures at cold-storage facilities could rapidly lead to shortages on supermarket shelves.
The organisation also highlighted the growing impact of the climate crisis, warning that flooding, extreme heatwaves and infrastructure failures could severely damage cold-storage operations that are essential for preserving food supplies.
Recent geopolitical developments have further intensified concerns. Continued disruption around the Strait of Hormuz has affected global fertiliser supplies, which are considered critical to approximately half of the world’s food production.
Industry leaders fear that prolonged instability in global energy and fertiliser markets could eventually drive food inflation even higher while reducing agricultural productivity both domestically and internationally.
Cold Chain Infrastructure Under Growing Pressure
The UK’s cold chain network forms one of the most essential yet least publicly visible components of the national economy.
Everyday grocery products including meat, dairy, fish, vegetables, fruit, bread and ready meals all depend on refrigerated transportation and storage systems before reaching retailers, restaurants, schools, hospitals and care homes.
Medicines, vaccines, blood plasma and temperature-sensitive pharmaceutical products also rely heavily on cold-chain infrastructure.
According to the CCF, food and medical products are distributed through approximately 460 cold-storage sites and transported by around 100,000 refrigerated lorries operating throughout the country.
Despite its importance, industry leaders argue that cold-chain infrastructure has not received sufficient strategic protection from government authorities.
Pluck criticised the government for failing to formally designate cold-storage facilities and food transport hubs as critical national infrastructure in their own right.
“We are recognised as critical national infrastructure by Russian cybercriminals, not by the UK government,” he said, revealing that businesses operating within the cold chain have recently faced repeated attempted cyber-attacks.
Concerns Over Cyber Security and Energy Resilience
Cybersecurity experts have increasingly warned that food logistics systems could become prime targets for hostile states or organised cybercriminal groups seeking to disrupt national infrastructure.
A successful cyber-attack affecting warehouse systems, transport scheduling or refrigeration controls could rapidly interrupt food distribution across large parts of the UK.
The CCF argues that official critical infrastructure designation would provide stronger government protections, including priority access to electricity supplies during large-scale power outages.
The federation believes such measures are urgently needed after recent global events exposed weaknesses in international supply chains during the Covid-19 pandemic and following Russia’s invasion of Ukraine.
Industry representatives also noted that Britain’s food resilience has not been significantly tested since the Second World War, when a substantial portion of the country’s cold-storage facilities remained under public ownership.
Tom Southall, deputy chief executive of the CCF, said this historical context has contributed to a dangerous level of complacency about long-term food security planning.
“This alludes to an element of complacency about how and where we store our food in the UK,” he said.
Previous Food Shortages Exposed Vulnerabilities
The UK has already experienced several food supply disruptions in recent years, highlighting the fragility of international logistics networks.
In early 2023, shortages of tomatoes, cucumbers and peppers affected supermarkets across Britain after poor weather conditions in southern Europe and North Africa reduced harvests. At the same time, soaring energy costs forced some UK and Dutch greenhouse producers to scale back production.
Several major supermarkets introduced temporary rationing measures on fresh produce purchases as supply shortages intensified.
Industry leaders fear that future disruptions involving energy supplies, cyber-attacks or geopolitical crises could produce far more severe consequences.
Pluck warned that food shortages can quickly lead to widespread social unrest, referencing riots that occurred in Venezuela during the country’s food crisis in 2016.
He added that lower-income households, vulnerable individuals and communities already struggling with the cost-of-living crisis would be most severely affected by any large-scale supply disruption.
Industry Calls for Government Action
The Cold Chain Federation has published a white paper outlining several recommendations aimed at strengthening Britain’s food resilience.
Among its proposals are calls for permanent essential-worker status for employees at major cold-storage and transport facilities, similar to the temporary protections granted during the pandemic.
The federation also wants the Cabinet Office to assume direct responsibility for overseeing national cold-chain resilience and emergency preparedness.
Industry leaders argue that protecting food logistics infrastructure should now be treated as a matter of national security rather than solely a commercial concern.
Government Defends Food Security Measures
In response to the criticism, a government spokesperson defended existing policies designed to strengthen food resilience and agricultural productivity.
“The food sector is one of the UK’s 13 critical national infrastructure sectors, and the cold chain is important to food supply to increase adaptability to disruptions that can occur,” the spokesperson said.
The government added that it remains committed to supporting domestic food production through investment in agricultural innovation, climate-resilient crops and new technologies aimed at improving long-term food security.
However, industry representatives maintain that far more urgent action is required to protect Britain’s increasingly fragile food supply system from future shocks.
