✦ Synopsis

A study was carried out to investigate the organisms associated with the spoilage of yam chips and flour in many locations in 5 states of Nigeria. Moniliniu fructicola, Aspergillusjhvus, A.,fumigatus, A . niger, Penicilliunz e.yutisum, P. wortmanni, P. duponti, P. funiculosum, Rhizopus sexualis, Piriculurin sp., Cladosporium cucumerinutn, Ifelnzinthosporiurn sp. and Mucor sp. were isolated and found to cause spoilage of the yam products. Araecerus ,fusciculatus, Tribolium cuslnrreutn and Ahasverus advenu were found on the yam chips as infesting insects. The yam chips or flour were either contained in exposed baskets or sealed in fibre bags in the market stalls. A..funzigutus had the highest occurrence. Most of the fungi were found not to sporulate heavily at a temperature of 10-15 "C while only spores of A.,fumigarus, A.flai*us and C. cucumerinum germinated at 32.5 Y;, relative humidity.
