Résumé
The cereal group occupies a prominent place in the dietary habits of the populations of southern Benin and there are few recent consumption data on cereals. This study aims to assess the consumption, acquisition and supply of cereals to households in Cotonou. A semi-directive survey with KoB°Collect was conducted with 345 households to collect individual cereal food consumption data. The survey data studied by inferential statistics showed that the most consumed cereals are corn (99%, p=l), rice (85%, p=0.936), wheat (35%, p=0.999), sorghum (15%, p=0.659), millet (10%, p=0.971) and fonio at less than 5%. The most common mode of acquisition is buying from secondary market (95%, p=0.987) and street (85%, p=0.999) retailers. The most used preservation techniques are: drying at room temperature (70%, p=0.619) and keeping the product away from light (30%, p=0.806). Households most often dry in areas laid out at home (70%, p=0.984) or at the edge of the road (30%, p=0.939). Storage places are very diverse: the kitchen (45%, p=0.871), the bedroom (40%, 0.998), the living room (25%, p=0.900) and the store (20, 0.931). In addition, the supply costs of cereals increased from 0.009 USD to 0.056 USD between 2020 and 2021. This vertiginous rise in prices is due to the covid19 pandemic. The various data emitted make it possible not only to have fresh data but also to invest them in the assessment of health risks for the achievement of a high level of protection of the health and life of consumers.
