The influence of season associated extrinsic factors, facility design and the geographical localization of schools participating in feeding programmes on the control and distribution of airborne organisms is not clear. Likewise, the impact of the resident bioaerosols on school occupants and the food stored in these facilities remains to be elucidated. Therefore this paper gives particular attention to the presence and distribution of indicator organisms in the food storage and classroom environment of schools (rural / urban) participating in a feeding programme in South Africa. From the results it emanated that though the storage facilities at the schools in question are, according to all technical data, not suitable for food storage; they did seem to govern some of the extrinsic factors that could influence bioaerosol viability. No control of these storerooms over the resident airborne bacteria was however noted. The results further identified the occupants of the schools as the possible source of the organisms present in the store rooms and not the building or the surrounding environment.
