The National Agency for Food and Drug Administration and Control (NAFDAC) has raised the alarm over the continued smuggling of banned and unregistered pesticides into Nigeria, warning that the illegal trade threatens public health, food safety and the environment.
The agency said prohibited agrochemicals were still entering the country through neighbouring nations, unauthorised border routes and informal distribution networks despite regulatory restrictions on their importation, manufacture, sale and use.
In a statement issued on October 9, 2026, NAFDAC Director-General, Professor Mojisola Adeyeye, said the illegal movement of banned and unregistered pesticides across Nigeria’s borders remained a serious concern.
Adeyeye said the agency had intensified surveillance, border checks and enforcement operations to disrupt illegal supply chains and prevent unsafe agricultural chemicals from reaching farmers and consumers.
Among the pesticides covered by the agency’s restrictions are products containing paraquat, chlorpyrifos and atrazine. NAFDAC said the applicable phase-out periods for the affected products had ended, meaning they could no longer legally be manufactured, imported, distributed, sold or used under the relevant prohibitions.
The agency disclosed that it seized banned agrochemicals worth more than ₦800 million across Ogun, Ondo, Osun and Oyo states in 2025.
Between September 2024 and July 2026, enforcement operations in the North-West resulted in the seizure, interception or recovery of 2,974 cartons of pesticides containing paraquat, valued at approximately ₦148.7 million. NAFDAC also reported the interception of 120 cartons of chlorpyrifos-containing pesticides worth more than ₦17 million during the period.
In a separate operation in Kebbi State, officials intercepted 5,619 cartons containing 67,428 litres of paraquat, alongside 500 cartons of atrazine products weighing approximately 5,000 kilogrammes.
The agency said these discoveries indicated that the problem extended beyond old stocks remaining in circulation, pointing instead to continued illegal importation, unauthorised local production and distribution.
NAFDAC also disclosed that four unauthorised agrochemical and pesticide manufacturing facilities were sealed in Bichi, Kano State, in July 2026. Officers reportedly found unlabelled products, bulk chemicals and packaging materials associated with illicit production. Suspects were arrested, and one case was said to be undergoing prosecution.
Beyond smuggling and illegal manufacturing, the agency expressed concern about pesticide residues detected in some food samples. A market study reportedly found pyrethroid and dimethoate residues above permitted safety limits in some samples of beans, raising questions about the use of chemicals on agricultural produce and the potential exposure of consumers.
Adeyeye stressed that NAFDAC was not opposed to the responsible use of pesticides, which remain important for protecting crops and supporting agricultural production. However, she said products used in Nigeria must meet regulatory requirements and be applied according to approved instructions.
The agency urged manufacturers and importers to comply with registration requirements, while distributors and agro-input dealers were advised to source products only through legitimate channels and avoid selling banned, unregistered or falsified pesticides.
Farmers were also advised to purchase agricultural chemicals from recognised dealers, follow approved label instructions and observe the prescribed waiting period between pesticide application and harvesting.
NAFDAC called on members of the public and other stakeholders to report suspected illegal pesticide products and activities through its official reporting channels.
The agency said it would continue working with relevant government institutions, border authorities, industry stakeholders and farmers to strengthen enforcement and protect Nigeria’s food supply.
