The report further indicated that the Food Index (year-on-year) declined by 1.33 percent from18.92 percent in January to 17.59 percent in February.
The report also said all major food sub-indexes increased during the month.
It stated that price movements recorded by All Items less farm produce or Core sub-index increased to 11.7 percent (year-on-year) in February.

Core inflation was 15.13 percent last month.
Dr Yemi Kale, the Statistician-General, had said in January that he expected that inflation would fall faster this year compared with 2017, but that spending ahead of 2019 presidential elections could stoke prices.
Food price inflation has remained in high double digits over the last year.
Kale said the country was in harvest period and output was increasing which would help lower food prices, but household consumption remained fragile after the 2016 recession.
