Abstract:
Insect infestation of stored grains is a huge problem among food vendors in Nigeria. The present study was carried out to determine the methods of preserving grain food among vendors in selected markets of Makurdi metropolis, Benue State, Nigeria. Questionnaires were administered to 60 vendors in three selected markets. Results showed that Guinea corn, maize, and rice were the most consumed grains on daily basis. Groundnut and maize had the lowest storage time prior to insect attack, while guinea corn had the highest. Insect attack on stored grain was high (91.7%). About 93% of the vendors applied insecticide, while 7% used the sun-dry method. Three types of insecticide were reported: insecticide powder, insecticide tablet, and insecticide spray. The sun-dry method was described as stressful and difficult or time-wasting. Vendors preferred the insecticide method because it is highly effective, time-saving, and easy to apply. Two disadvantages of the chemical method include the possibility of causing harm to humans and the high cost. The safety of food grains sold to consumers is in doubt. This calls for appropriate regulatory measures among stakeholders.
