Food prices averaged at 179.4 points in February, down from 181.2 points in January and 208.6 points in February 2014, the Food and Agriculture Organization's price index showed.
FAO's Food Price Index is a trade-weighted index that tracks prices of five major food commodity groups on international markets. It aggregates price sub-indices of cereals, meat, dairy products, vegetable oils and sugar.
"Food Price Index declined to a 55-month low in February, dropping 1.0 per cent from January and 14 per cent below its level a year earlier," FAO said in a statement.
"The first thing to flag is the favorable outlook for production of a number of crops in 2015," he said. "Stocks are also very strong" for most cereals, he added.
According to FAO, international sugar prices fell by 4.9 per cent, cereal prices were down by 3.2 per cent and meat prices declined by 1.4 per cent in February from the January levels.
However, international prices of dairy products and vegetable oil increased by 4.6 per cent and 0.4 per cent in February from the January levels.
