37 Notices, 206 Samples Tested, Substandard Oil Worth Rs 6.43 Crore Seized Across UP Ahead Of Holi

Ahead of Holi and Eid, and during Ramadan, when demand of cooking oil spikes for meal preparation, every year, substandard quality items hit the market. This year too this happened and to curb this practice, the Uttar Pradesh Food Safety and Drug Administration (UPFSDA) issued 37 notices for non compliance to sellers selling substandard oil. The Food Safety Department also seized oil worth Rs. 6.43 crore. 

The UPFSDA inspected 64 manufacturing units across Uttar Pradesh and seized 4,16,494 litres of suspicious edible oil.

<h2 style="">What Is Substandard Oil?</h2>

Substandard cooking oil refers to edible oils that are adulterated, improperly refined, reused, or of low quality, often containing harmful compounds due to poor manufacturing, such as high-heat processing or chemical contamination. <span>FSSAI</span> reports have indicated that up to 30.7% of edible oils in some markets are of poor quality or adulterated. 

As per a 2024 study published in the<em> International Journal of Biochemistry and Molecular Biology</em>, common oil sources shows that most edible oils are extracted from seeds, while certain fruits such as olives, coconuts, and palm fruits are also used to produce oil. However, adulteration remains a major concern. Oils like Argemone oil, mineral oil, castor oil, karanja oil, olive oil, cottonseed oil, and paraffin oil are often blended with edible oils and ghee. Some adulterated products may even contain toxic substances such as cyanide and banned colouring agents.

Mustard oil and soybean oil are particularly vulnerable to adulteration through the deliberate addition of substances such as cyanide, mineral oil, karanja oil, Argemone oil, and linseed oil—practices that pose serious risks to consumer health and safety. Similarly, sesame oil is frequently mixed with other oils including avocado, olive, canola, walnut, peanut, and perilla oils.

Argemone oil, in particular, is derived from the seeds of the Argemone mexicana plant and is commonly mixed with mustard oil. Its seeds are spherical, blackish-brown, and have a net-like surface, closely resembling mustard seeds, which makes detection more difficult.

<h2>What Happens When You Consume <span rel="noindex">Adulterated Edible Oils</span>?</h2>

Adulteration, in general, makes edible oils and ghee unsafe for consumption and significantly reduces their nutritional value. According to the Indian Council of Medical Research, many adulterants can cause permanent organ damage. History offers stark warnings: in Spain, the sale of non-edible rapeseed oil falsely marketed as olive oil led to more than 600 deaths in what became known as the Spanish toxic oil syndrome.

Argemone-contaminated oils have triggered major outbreaks in several countries, including a severe epidemic dropsy crisis in New Delhi in 1998. Reported symptoms included retinal haemorrhages, anaemia, kidney dysfunction, and severe protein deficiency. Some adulterated oils may also contain carcinogenic substances such as polycyclic aromatic hydrocarbons (PAHs), increasing long-term cancer risk.

Other adulterants pose additional dangers. Castor oil contamination can cause severe gastrointestinal distress. Mineral oil adulteration is linked to liver toxicity and cancer risk. Cottonseed oil, when improperly blended, increases exposure to high levels of polyunsaturated fats, potentially contributing to obesity, diabetes, and other lifestyle-related diseases. In some alarming cases, soybean and mustard oils have been found adulterated with burnt mobil oil containing polychlorinated biphenyls (PCBs), toxic chemicals associated with liver damage, neurological changes, dehydration, respiratory irritation, and systemic organ harm.

Adulteration can also trigger allergic reactions. If peanut oil is used as an undeclared adulterant, it may cause severe allergic responses in susceptible individuals.

The most concerning aspect is that loose or unpackaged edible oils are more prone to contamination and adulteration. What may appear to be a simple cost-cutting practice can, in reality, expose consumers to life-threatening toxins, chronic disease risks, and irreversible organ damage.
