	bibo:abstract "The present study sought to identify household risk factors associated with aflatoxin contamination\r\nwithin and across diverse Indian food systems and to evaluate their utility in risk\r\nmodeling. Samples (n = 595) of cereals, pulses, and oil seeds were collected from 160\r\nhouseholds across four diverse districts of India and analyzed for aflatoxin B1 using\r\nenzyme-linked immunosorbent assay (ELISA). Demographic information, food and cropping\r\nsystems, food management behaviors, and storage environments were profiled for\r\neach household. An aflatoxin detection risk index was developed based on household-level\r\nfeatures and validated using a repeated 5-fold cross-validation approach. Across districts,\r\nbetween 30–80% of households yielded at least one contaminated sample. Aflatoxin B1\r\ndetection rates and mean contamination levels were highest in groundnut and maize,\r\nrespectively, and lower in other crops. Landholding had a positive univariate effect on\r\nhousehold aflatoxin detection, while storage conditions, product source, and the number of\r\nprotective behaviors used by households did not show significant effects. Presence of\r\ngroundnut, post-harvest grain washing, use of sack-based storage systems, and cultivation\r\nstatus (farming or non-farming) were identified as the most contributive variables in stepwise\r\nlogistic regression and were used to generate a household-level risk index. The index had\r\nmoderate classification accuracy (68% sensitivity and 62% specificity) and significantly correlated\r\nwith village-wise aflatoxin detection rates. Spatial analysis revealed utility of the\r\nindex for identifying at-risk localities and households. This study identified several key features\r\nassociated with aflatoxin contamination in Indian food systems and demonstrated that\r\nhousehold characteristics are substantially predictive of aflatoxin risk."^^xsd:string;
