Taste of Fear: How Adulterated Palm Oil Is Shattering Trust In Lagos Markets

CYRIACUS IZUEKWE

In Oyingbo Market, palm oil is not just a cooking ingredient. It is colour, it is aroma, it is memory. A good red oil tells you the soup is ready before it even boils.

But this September, that trust is shaking.

Goodness Okoro, a resident of Apapa Road, still remembers the pot of egusi she cooked last week. She poured more oil than usual, expecting that rich, reddish glow. It never came.

“I used plenty oil, but the soup looked pale. The taste was flat,” she said. “I started wondering, what did I just feed my children?”

She is not alone. Across Lagos, from Ikotun to Costain, consumers and traders are raising fresh concerns over suspected palm oil adulteration, a scare that has now caught the attention of the Lagos State Government.

When Did It Start? The Data

The problem is not new, but it has worsened sharply in the last two years. Industry data shows Nigeria needs over 3 million tonnes of palm oil yearly but produces only 1.4 to 2.5 million tonnes, creating a massive supply gap.

The National President of the Oil Palm Growers Association of Nigeria, Joe Onyiuke, confirmed that scarcity and pressure on the local market pushed criminals into the business, noting Nigeria now produces only about two per cent of global output. He described adulterated palm oil being sold openly in major markets as a national emergency.

Investigations in late 2025 found greedy wholesalers and retailers adding industrial dyes to freshly milled oils to increase quantity and profit. By 2026, the practice has become more sophisticated, with multi-adulterant mixtures designed to evade basic quality checks. NAFDAC disclosed it now receives over 200 complaints monthly, with 225 calls received in August alone.

Who Is Responsible?

Experts blame a chain of unscrupulous actors: bulk blenders who mix fresh oil with cheap additives, middlemen distributors chasing higher margins, and some market retailers who repackage the product.

According to food safety expert Dr. Nurah Oseni of Auchi Polytechnic, palm oil is vulnerable because of high trading volume, consumers’ association of deep-red colour with quality, price differences, informal market practices, and challenges in detecting sophisticated adulterants.

Common adulterants now include water, starch, candle wax, transformer oil, recycled spent cooking oil, and most dangerously, industrial colourants like Sudan IV, Sudan III, Azo dyes, Rhodamine B and Metanil Yellow.

Health Hazards Of Adulterated Oil

Medical experts say this is a slow poisoning.

Dr. Kunle Ashimi, Chief Medical Officer at the Federal Medical Centre, Abeokuta and former Chairman of the Nigerian Medical Association, Ogun State Branch, warned that eating these non-edible chemicals, even in tiny daily amounts, causes severe, irreversible damage over time.

He explained: “Industrial azo dyes primarily used in the textile industry, waxes and plastics are fraudulently added to palm oil to impart a deep, vibrant red colour.”

The health implications include:

1. Cancer risk: Sudan dyes are classified as Group 3 carcinogens by the International Agency for Research on Cancer. Once ingested, gut microbes and liver enzymes change them, causing genetic damage that significantly elevates the long-term risk of liver, kidney and bladder cancers.

2. Organ damage: Prolonged exposure can damage vital organs, particularly the liver and kidneys.

3. Other complications: Stomach problems, abdominal pain, skin reactions, digestive problems, allergic reactions and reproductive complications.

Nutritionists add that blending with recycled cooking oil introduces free radicals and other harmful compounds that further compromise human health.

Government Reaction

The Lagos State Consumer Protection Agency (LASCOPA) issued a fresh alert at the 2026 Lagos State Food Safety Conference and Exhibition.

LASCOPA General Manager, Afolabi Solebo, reassured residents that officials are monitoring the situation closely. He said: “We have intensified market surveillance across the state. We urge Lagosians to shine their eyes, buy from trusted sources, and report any suspected adulterated palm oil through our official channels. Anyone caught selling adulterated palm oil will face the full wrath of the law.”

Dr. Oseni also proposed a five-step surveillance framework for Lagos: Risk Map, Sample, Screen, Confirm and Act, backed by an adulteration intelligence database involving processors, traders, laboratories, regulators and consumers.

What Consumers Can Do

For many buyers, detection has become a domestic science. Chidinma Nwabueze, a palm oil trader at Oyingbo, says she now survives on reputation.

“I source from trusted factories and major suppliers. My customers know me,” she said. “But some new oils in the market, you will see the colour is too red, the thickness is strange.”

Mummy Joy of Ikotun says she judges with her eyes and tongue. Okoro Ebube of Costain swirls the bottle, watches the sediment settle, and sniffs.

Experts advise: authentic palm oil may separate into layers, with the lower layer appearing orange to red-yellowish rather than uniformly deep red. Be wary of unusually cheap oil, excessive redness, strange chemical smell, or bitter aftertaste.

Back in Oyingbo, Nwabueze scoops a spoonful of her own stock and holds it to the light. Thick, deep red, with that nutty palm aroma.

“This is the real one,” she smiles. “Once you know it, you know.”

But for thousands of Lagos mothers like Goodness Okoro, knowing is no longer enough.

“I just want to cook without fear,” she said, staring at her half-used keg. “Is that too much to ask?”

As demand for palm oil peaks ahead of the Independence celebrations, regulators face a test that will play out not in conference halls, but in market stalls and family kitchens.
