20+ Countries Regulate Frying Oil. The United States Is Not One of Them.

The regulatory map

In 1973, the German Society for Fat Science (DGF) established the first quality standard for commercial frying oil, linking polar compound levels to food safety and sensory quality. Over the following five decades, more than 20 countries adopted mandatory Total Polar Material (TPM) limits.

24% TPM: Germany

25% TPM: France, Spain, Italy, Belgium, Portugal, Netherlands, Poland, Czech Republic, Hungary, Switzerland, Austria, Brazil, Chile, South Africa, Turkey, India (FSSAI)

27% TPM: China (national standard GB 2716-2018, implemented December 2018), Japan, Malaysia

Belgium and the Czech Republic enforce an additional sublimit: combined triglyceride dimers and oligomers (TGD + TGO) cannot exceed 10% of oil weight — targeting the polymer fraction that indicates advanced thermal degradation.

The Codex Alimentarius, the international food standards body jointly operated by the WHO and FAO, sets a reference limit of 25% TPC.

How enforcement works

In the European Union, member states enforce frying oil standards through official controls carried out by designated competent authorities. Enforcement includes scheduled inspections, unannounced audits, and financial penalties. EU Regulation on official controls introduced penalties that must reflect the economic advantage gained by the operator — meaning fines are scaled to business size, not flat amounts.

Non-compliance can result in fines, mandatory product recalls, and in severe cases, criminal prosecution. The enforcement infrastructure is the same system that enforces all food safety regulations — frying oil is not treated as a separate category but as part of the standard inspection regime.

The US gap

The United States has no federal mandatory TPM limit for frying oil. The FDA Food Code does not address frying oil polar compounds. There is no mandated discard point, no required testing frequency, no disclosure requirement, and no certification for the personnel managing frying oil.

The USDA Food Safety and Inspection Service (FSIS) provides general consumer guidance on deep-fat frying — recommending oils with high smoke points and safe temperature practices — but sets no enforceable oil quality parameters. USDA school meal nutrition standards address fat content in meals but do not regulate frying oil quality or replacement frequency.

No state has enacted binding TPM legislation. No bill addressing frying oil quality standards has been introduced at the federal or state level in the past five years. The regulatory gap is not closing — it is not even being discussed.

What the chains do internally

The absence of regulation does not mean the largest operators are unmanaged — it means the standard is set by corporate policy, not law.

KFC uses a canola/hydrogenated soybean oil blend and has partnered with Restaurant Technologies for automated oil management systems. Their internal protocol includes daily filtration, free fatty acid testing via strips and color comparison charts, and scheduled replacement based on quality checks.

McDonald's operates open-vat deep fryers with time/temperature protocols. Chick-fil-A uses pressure fryers with peanut oil. Both chains have internal oil management standards — but the specifics are not publicly disclosed, and they apply only to franchised locations within their systems.

The result is a two-tier market: large chains with resources to develop and enforce internal standards, and the remaining 800,000+ independent restaurants and small operators with no standard at all.

The economic dimension

The US restaurant industry generates approximately 3 billion gallons of used cooking oil annually. Over 4.4 billion pounds of UCO is collected from US and Canadian restaurants for recycling — but only an estimated 10–20% of UCO produced in foodservice is currently collected.

Oil costs now consume 10–12% of a fried-food-specialist restaurant's total food costs, up from 7–8% three years ago. Kitchens that filter properly and manage oil to a standard can cut oil costs by up to one-third. The economic argument for managed oil is not marginal — it is one of the largest controllable cost centers after labor.

The health dimension

The health case for regulation is not hypothetical. Degraded frying oils produce toxic polar compounds and aldehydes that promote systemic inflammation, oxidative stress, and endothelial dysfunction. Grootveld et al. (2018, HepatoBiliary Surgery and Nutrition) demonstrated that lipid oxidation products from PUFA-rich oils at frying temperatures are cytotoxic and genotoxic at measured concentrations.

Epidemiological studies link frequent fried food consumption to heightened risks of cardiovascular events — but the existing studies do not control for oil quality. A diner eating food fried in properly managed oil at 12% TPM has a fundamentally different exposure than one eating food fried in degraded oil at 30% TPM. Without regulation or disclosure, there is no way to distinguish between the two.

What NCOMA is doing about it

NCOMA exists because the regulatory gap will not close on its own. The FDA has not signaled interest in frying oil standards, and no state legislature is pursuing the issue. The association's approach is voluntary, industry-built certification that creates a market mechanism where regulation does not exist.

The WIYO! seal tells diners that a kitchen manages its oil to a published standard — daily filtration, TPM testing, 25% discard threshold, trained staff, documented records. It does not require legislation. It requires operators who believe the standard matters and diners who ask the question.

The goal is not to wait for regulation. It is to make regulation unnecessary by building a standard the industry adopts because it is right — for the food, for the economics, and for the people eating it.
