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
