The commensal rodents causes serious damage to stored food not only by consumption but also by contamination through their filth exhibits. The present study was carried out in an inner city grain market of Rawalpindi to determine the extent of contamination by rodent hairs and pellets. From randomly selected eight shops six grain commodities: rice, millet, split lentil (Dal Masoor), split Mung bean (Dal Mung), split black gram (Dal Mash) and split chickpea (Dal Chana) were sampled from top of the open bags. None of the shops inspected was negative for rodent signs. Rice was found to be one of the most infested grains followed by millet, Dal Masoor, Dal Mash, Dal Chana and Dal Mung. Overall estimates of rodent filth contamination indicated level of faeces; by weight at 0.083 g kg- 1 and by counts at 6.7 kg-1, and hairs at 4.2 kg-1, the both being at 10.8 kg-1.
