On 28 February 2026, Israel and the US launched strikes against Iran. By 1 March, Iran had announced closure of the Strait of Hormuz—a shipping corridor that handles roughly one-fifth of global oil and gas trade. Shipping through the Strait has largely ceased. A ceasefire was announced on 8 April 2026, but the US naval counter-blockade remains in place. For UK food manufacturers, this is not a geopolitical abstraction. It is a supply chain crisis that is now creating acute food fraud vulnerability.
One-third of global fertiliser trade passes through the Strait. The closure has already forced UK food manufacturers into a desperate scramble for alternative suppliers. When legitimate supply chains fail and time pressure is high, fraud risk explodes.
What Happened — The Supply Chain Collapse
The Strait of Hormuz is a critical chokepoint for global trade. Closure means oils, fats, fertilisers, and specialty ingredients sourced from the Gulf region or transiting through the Strait now face uncertain delivery schedules or simply cannot arrive. UK manufacturers importing 80 percent of fresh fruit and over half of vegetables cannot absorb long delays. Payment defaults in the UK food and drink sector surged by 50 percent between February and March 2026, compared to the same period last year — a clear signal that suppliers could not fulfil orders and that manufacturers were forced to seek alternatives.
Red diesel costs for agriculture have risen approximately 60 percent. Fertiliser shortages are already evident. The Food and Drink Federation revised its UK food inflation forecast to over 9 percent by the end of 2026, up from 3 percent forecast in January.
Why This Creates Food Fraud Risk — The Supplier Verification Collapse
Normal supplier verification takes time. Audits, certificates, third-party testing, facility visits — these are the controls that prevent fraudulent or non-compliant ingredients entering your supply chain. They work when you have time to be selective. The Strait closure eliminates that luxury.
When your regular dairy supplier cannot deliver because their ingredient inputs are stuck in shipping queues, and you have orders due in 48 hours, you do not have time for a full supplier audit. You accept a contact referral from a broker, request a certificate via email, and move forward. This is how fraud enters the system.
Food fraud risk assessment research from 2026 shows processed foods and dairy are now the highest-risk categories — exactly the sectors most dependent on imported fats, oils, and specialty ingredients transiting through Middle Eastern routes. Ingredient dilution (oils extended with cheaper alternatives), substitution (lower-grade fats passed as premium), and mislabelling (products sourced from unverified facilities) are all accelerating.
The fraud works because it exploits a real constraint: you genuinely need the ingredient, you genuinely do not have time for full verification, and the fraudster understands this desperation.
What Manufacturers Must Do Now — Emergency Supplier Controls
1. Establish an Emergency Approved Supplier List
Do not wait for the Strait to reopen. Now, while there is still time, identify 2–3 backup suppliers for every critical ingredient. Conduct abbreviated but rigorous verification: unannounced verification calls (speak directly to named contacts), certificate verification through the issuing body (not email copies), and commitment to third-party testing on first delivery. Document this. When you are under time pressure in a crisis, you will refer to this list, not to broker referrals.
2. Implement Post-Delivery Ingredient Testing for High-Risk Categories
Dairy, oils, fats, and specialty ingredients should be tested on receipt — not just for microbiological compliance, but for authenticity markers. Isotopic analysis for oils, FTIR spectroscopy for fats, DNA testing for dairy proteins. If incoming product does not match the certificate, stop production and initiate investigation immediately. Do not assume the certificate is correct.
3. Document Your Supplier Fraud Risk Assessment
Complete a VACCP (Vulnerability Assessment Critical Control Point) or TACCP (Threat Assessment Critical Control Point) exercise focused on supply chain disruption. For each critical ingredient, document: the normal source, backup sources, what happens if primary source fails, and how you will verify emergency suppliers. This is now a BRC audit question — auditors will ask how you protect against fraud during supply chain stress. Have documented answers ready.
4. Communicate Supplier Verification Timelines to Procurement
Brief your procurement team: if a supplier contact cannot be verified within 4 hours (unannounced call to named contact), do not proceed. If a certificate cannot be verified with the issuing body within 24 hours, do not proceed. If incoming product fails authenticity testing, reject it. Procurement needs to understand that accepting fraud risk to meet a deadline is not cost reduction — it is a compliance failure that will be discovered in audit or recall.
Strengthening Your HACCP System — Supply Chain Verification as a PRP
Supplier verification is a prerequisite programme (PRP) in HACCP, not a CCP. But it is foundational. Every ingredient entering your facility is a potential source of hazard — biological, chemical, or physical. Your hazard analysis must now specifically identify "supplier fraud or ingredient substitution" as a documented hazard, with supplier verification (unannounced calls, certificate checks, receipt testing) as your documented control measure.
SafetyCore's prerequisite programme framework allows you to link supplier verification directly to your risk assessment. You define the verification frequency for each ingredient category, assign responsibility, and document evidence of completion. The immutable audit trail shows every verification action timestamped and locked. When the FSA or a BRC auditor asks how you protect against fraud, you have a structured record of your due diligence.
What You Should Do This Week
Identify your top 10 ingredients by volume. For each, identify your current primary supplier and your backup source. Call both suppliers today and confirm their status: Are they experiencing delays? Can they currently fulfil orders? How has the Strait closure affected them? Document the responses. For dairy and oils specifically, plan a testing programme — source a laboratory that offers authenticity testing and budget for it over the next three months. When procurement raises a new supplier, do not say yes until you can verify the contact through an unannounced call and the certificate through the issuing body.
The Strait may reopen. Supply chains may normalise. But the fraud risk created by this disruption will persist for months. Criminals exploit these windows. Your supplier verification controls need to be robust now.
If you're documenting your supplier verification and supply chain fraud controls after reading this, SafetyCore gives you a structured way to link it to your risk assessment and maintain a timestamped, immutable audit trail. Start a free trial at safetycore.co.uk.

LinkedIn Summary: The Strait of Hormuz closure is a supply chain crisis. When fertiliser, oils, and ingredients get stuck, manufacturers turn to alternative suppliers under time pressure. Fraud exploits desperation. Payment defaults up 50%. Dairy and oils highest risk. Your supplier verification needs to survive supply chain stress. #FoodSafety #SupplyChain #FraudRisk
