Household food security in Capurganá and Sapzurro and the association with the collection and the consumption of the snail Cittarium pica is described. A cross sectional-study was carried out in a representative sample of 126 households obtained using a probabilistic sampling. A food security perception scale was applied to determine its severity, and other characteristics were collected through a survey. Statistical analysis was done using the chi-square test, the U mann whitney test, odds ratio along with its confidence intervals and the correspondence multiple analysis. More than half (54,8%) of households were in food insecurity. Food insecurity was significantly associated with low income (p=0,0003), direct collection of the snail (p=0,0178), education level of the head of the household (p=0,0014) and the money spent on food (p=0,0000). The current use of the snail does not contribute to the household food security
