Food inflation declined marginally to 9.47 per cent for the week ended September 3, with prices of all items, barring pulses and wheat, rising on an annual basis. Food inflation, as measured on the basis of the Wholesale Price Index (WPI), stood at 9.55 per cent in the previous week. The rate of price rise of food items was 15.16 per cent in the corresponding week of 2010.As per data released by the government today, prices of pulses fell by 2.45 per cent year-on-year, while wheat became cheaper by 2.03 per cent. However, other food items became more expensive during the week under review.The fall in food inflation could be attributed to a moderation in the rate of price rise of some of the items on a week-on-week basis, even though they remained higher on an annual basis. The decline could also be attributed to the high inflation of over 15 per cent in the corresponding year-ago period.
