Warsaw Business Journal reports that, according to experts from the Institute of Agriculture and Food Economy, by December of this year food products and non alcoholic beverages may cost between 4.0 and 4.2 per cent more than a year earlier. In first half of this year, food products were 4.5 per cent more expensive than the same period of 2008.

The largest price increases were recorded in pork and poultry, which jumped 10 per cent on average, according to Rzeczpospolita. For vegetables, the increase was 9.6 per cent.

"In September, the seasonal increase in food prices began. This year, however, it should be much slower than the previous year," commented Krystyna Swietlik from the Institute.
