Osinbajo Sounds Food Safety Alarm as Wife Suffers Strange Headaches from Chemically Ripened Oranges

Former Vice-President Prof. Yemi Osinbajo has raised a national alarm over the unregulated use of hazardous chemicals in food preservation and fruit ripening across Nigeria, recounting how his wife, Dolapo, fell ill after drinking freshly squeezed orange juice that laboratory tests later declared unfit for human consumption.

Addressing participants at the Open Day for Gardeners’ Seminar in Lagos, held under the theme “Leaving the Earth Better Than We Found It,” Osinbajo shared the personal ordeal to illustrate the grave public health risks lurking within everyday market produce.

According to the former vice-president, his wife had resolved to abandon carbonated soft drinks in favor of a clean, healthy lifestyle anchored on a daily glass of freshly squeezed orange juice. However, the routine took an unexpected turn when she began experiencing recurring, strange headaches.

Initially, the family ruled out the fruit juice, assuming that natural, raw citrus could not possibly be the source of the ailment. When an exhaustive check of her meals and hydration habits revealed no other anomalies, Mrs. Osinbajo dispatched a sample of her freshly squeezed batch to an accredited laboratory for toxicological and chemical screening. The laboratory results confirmed their worst fears: the juice—extracted directly from market-bought oranges—was saturated with dangerous chemical residues and deemed completely unsafe for consumption.

Osinbajo linked the contamination to the rampant practice among local farmers and produce merchants who drench crops in toxic agrochemicals and artificial ripening agents to accelerate sales and cut shelf-life losses. He singled out the widespread application of calcium carbide—a hazardous compound commonly used by welders—which vendors employ to force unripe mangoes, bananas, pawpaws, tomatoes, and citrus fruits to change color overnight to appear ripe and juicy.

Beyond ripening agents, the law professor cautioned that produce in Nigerian markets is frequently contaminated with banned and lethal substances, including Gammalin 20, highly toxic fumigants, organophosphate pesticides like Sniper, DDT, and hazardous rodenticides.

Underlining the severity of the crisis, Osinbajo cited recent field investigations from different parts of the country. In an Ado-Ekiti study, half of the fruit sellers interviewed openly admitted to using calcium carbide, while a similar inquiry in Uyo revealed that 25 percent of vendors relied on the chemical. In commercial markets across Lagos, 22 out of 50 surveyed fruit and vegetable retailers acknowledged treating their wares with chemical preservatives.

Emphasizing that visual appeal can be deceiving, Osinbajo warned consumers that a bright peel and natural appearance offer no guarantee against poisonous additives introduced along the supply chain. He challenged food safety authorities, including the National Agency for Food and Drug Administration and Control (NAFDAC) and agricultural inspectors, to tighten market surveillance, enforce punitive sanctions against defaulting vendors, and educate farmers on organic alternatives before chemical contamination turns into an irreversible public health epidemic.
