There is concern about the conditions of food and nutritional security of Brazilian population. In Brazil, according to Law no. 11,346 in 2006, featuring the food and nutrition security as a multidimensional process, being determined by factors ranging from agricultural production, food distribution and access to population, economic access to food, even the food choice, based on cultural components. Many instruments are used to determine the food security situation, and these instruments do not allow an evaluation of the data at the municipal level, which difficulties the decision to qualify each cities. Thus, this study presents a methodology that considers various factors related to a situation of uncertainty through the application of fuzzy logic, and therefore the purpose of analyzing the food security situation of cities of Paraíba through the application of fuzzy logic, describing factors associated with this situation in order to help decision making and prioritizing interventions, supporting the process of planning programs and rules. In epidemiology situations lead the researcher to complex issues, imprecise and uncertain, and fuzzy sets theory is applied in such cases by its ability to deal with such situations of uncertainty. Besides the application of the decision model of fuzzy logic, we performed a spatial analysis, where the 221 cities were identified, according to the food security situation. The results therefore show that 48% of this cities are in the food security situation of risk, followed by 33.5%, which are in an acceptable, and 18.5% in unacceptable conditions. These data draw attention to the characterization of the situation in Paraíba, with 106 municipalities at risk and 41 in unacceptable conditions, which are the municipalities as priorities for intervention. It is evident therefore that the methodology adopted is to be an important tool to define the trends priority intervention in the municipality in order to allow identification of the food security situation in this sphere of government and may support the decision making and planning actions aimed for promotion food security.
