The objective of this work was to know the socioeconomic and sanitary conditions of households in Chapecó (SC) as dimensions of Food and Nutrition Security. We surveyed 774 households from urban and rural areas. The majority of households heads are women (68.8%); 8.4% of the households heads are illiterate, 62.4% have primary education, 20.93% high school and 7.8% have highereducation (incomplete/full, respectively); The average family monthly income was 1.803,8 dollars. The water supply in urban area is done by the public system (84%) and in rural area comes from wells/sources (50.2%). The public sewer system exists only in urban areas (23.4%); 75.4% of the households conduct sewage for tanks in urban area and 99% in rural area. It is considered the household incomes observed facilitate the access to food; however the level of education of more than 70% of household heads is equal to or less than primary education. This may imply the lack of knowledge about hygiene care and food handling. The large number of families who conduct sewage for tanks and that use water from sources/wells for drinking water may prejudice their Food and Nutrition Security condition.
