Safety net-supported households participating in the Productive Safety Net Program (PSNP) arerninvolved in public works to make them food secure in sustainable way. But there is insufficientrninformation on the level of their knowledge,attitudeand practice (KAP) related to food handling,rnpersonal hygiene and water sanitation.The general objective of the study was to investigaternnutritional status, food safety KAP and food security status of PSNP-supported households inrnworeda two of Addis ketema sub-city, Addis Ababa. A cross-sectional survey was carried outrnamong PSNP-supported households in the study area, betweenJanuary andMarch 2019.rnPurposive sampling technique was applied to select the study woreda, and the study population.rnStudy households were selected by systematic random sampling technique. A total of 273rnhousehold were selected, from among PSNP supported households involved in public work, asrnsample size.Data was analyzed by using SPSS version 25 through descriptive and Crossrntabulation was used to analyze the association between socio economic factors and nutritionrnstatus. Majority (82.2%) of the household food handlers and public workers under PSNP werernfemales and (17.92%) were males where most of the study population (74.71%) were >46 yearsrnof age.The KAP analysis indicated that food handling knowledge,positive attitudes andrnacceptable practices among the study population was less than 50%.
