hello and welcome to healthcare magic forum! Eating raw rice may be a form of a disorder called pica. Pica is an appetite for non-foods (e.g., paper, coal, chalk etc.) or an abnormal appetite for some things that may be considered foods, such as food ingredients (e.g., fllour, raw potato, raw rice, starch). Exposure to infectious agents via ingestion of contaminated rice is a potential health hazard associated with pica, particularly if the rice is unwashed. It is usually indicative of some form of underlying nutritional deficiency. Please see ur doctor who will evaluate ur problem perhaps start dose of vitamin or mineral supplements. Pica is a also a habit which would require psychologic counselling or aversion therapy for a cure of the behavioural disturbance. Good wishes
