Groundnut storage problems were studied in Cote d'Ivoire during two successive storage periods (1985/86 and 1986/87). Locally stored samples were a little less infested than samples taken from markets. With few exceptions, all the locally sampled material was contaminated with measurable levels of aflatoxin. Over the 2-year survey period, 7.9 per cent of the 434 local stocks examined exceeded the toxicity level threshold of 250 micro gms per kg, with 4.4 per cent above 1000 micro g/kg. It was also found that 73 per cent of these samples were above the safety level of 10 micro g/kg. Significant correlations were found between aflatoxin contamination and different storage and meteorological variables. These included physical characteristics and age of the pods, and the influence of the atmospheric conditions
