Nigerian Stored Products Research Institutes (NSPRI) was established in 1954 to conduct research in all aspects of post harvest handling of agricultural crops and their products, pesticide development, residue analysis and mycotoxin surveys on food items in Nigeria as stated in Decree 5 of 1977. NSPRI was also established to produce low and medium level technical manpower in produce inspection, post harvest handling of food and pest control. Although, her focus before independence was on export crops but her mandate was expanded to include research into local food crops, extension and training. To perform these activities the Institute, apart from its headquarters that is located in Ilorin, Kwara State, Nigeria, has the following outstations established on ecological zone basis.

South-South Zone:
NSPRI Port Harcourt, Rivers State
NSPRI Sapele, Delta State

South-West Zone:
NSPRI Ibadan, Oyo State
NSPRI Lagos, Lagos State

Central Zone:
NSPRI Headquarters, Ilorin, Kwara State

Northern Zone:
NSPRI Kano, Kano State
The College of Produce Inspection and Pest Control offers Certificate and Diploma courses and it is located in Kano, Hadeja Road, Kano State.

Vision Statement
To provide adequate management facilities for the handling of Nigeria’s agricultural produce for achieving self-reliance in post harvest loss prevention.
