Kathmandu - A UN agency is under scrutiny after the food aid it distributed to earthquake survivors in Nepal was found to be substandard, authorities said on Monday."A team of a parliamentary monitoring committee has arrived in Nepalganj to inspect the five food storage locations of the WFP [World Food Programme] here," said Bed Prakash Lekhak, chief officer of Banke district."The storage had to be inspected after the rice distributed to the earthquake victims in Gorkha district last week was found to be of inedible quality.Samples of rice and pulses have been taken for investigation, the official added.Local media reports said 542 tons of pulse stores in different locations in Nepalganj were also found to be of poor quality.RecommendationsBut the WFP said the stored pulses were not meant for distribution because they had already been rejected as sub-standard.The WFP was criticised in May after rice it distributed in Kavre district was found to be rotten and caused diarrhoea among children."We have already withdrawn the sub-standard supplies and replaced them and I think that has already been dealt with," the UN resident co-ordinator in Nepal Jamie McGoldrick said after the earlier incident.The committee will submit recommendations to the government for action after making their finds public.At least 8 831 people were killed in two earthquakes that hit Nepal in April and May. Thousands have been left homeless.
