In several Nigerian towns, including Lagos, street sellers have begun mixing melted polyethylene bags with the oil used to fry plantain chips, a shortcut that lengthens the snack’s freshness but introduces toxic substances into the food.
Why are vendors resorting to plastic?
The cost of essential inputs—vegetable oil, cooking gas and raw plantains—has roughly tripled over the past two years. For entrepreneurs like Halima Mohammed, who runs a roadside frying stall, raising the price of a small packet from N200 to N400 would drive away customers, especially students. To avoid price hikes, vendors melt clear plastic bags in hot oil, creating a glossy layer that coats the chips and prevents moisture absorption, stretching shelf‑life from two days to over two weeks.
What health risks does the practice pose?
When polyethylene melts, it releases carcinogenic compounds, heavy metals and micro‑plastics that embed in the fried product. Regular consumption can increase the likelihood of liver and kidney damage and elevate long‑term cancer risk. Public health specialist Dr. Duro Ifagbemi warned, “We are looking at a ticking time bomb of gastrointestinal complications and cancer cases,” adding that poverty forces people to ignore these dangers.
How are authorities responding?
The Federal Ministry of Health and the Nigerian Food and Drug Administration and Control have issued alerts against street foods prepared with plastic additives, but enforcement is hampered by the sheer size of the informal sector, where countless fryers operate from unregistered backyards. Without viable economic alternatives, many micro‑entrepreneurs feel compelled to adopt hazardous shortcuts.
What does this mean for consumers?
Millions of commuters rely on cheap, portable snacks during long journeys. While the crunchy texture remains appealing, the hidden plastic coating turns a simple treat into a potential health hazard. Until macro‑economic pressures ease, the cost of a roadside plantain chip will carry a hidden price far beyond the few Naira paid on the pavement.
