Global meat prices have hit a 20-year high as robust demand from emerging countries has coincided with a drop in production by exporters such as the US and Australia, fuelling concerns about rising food inflation.

The UN Food and Agriculture Organisation’s index of meat prices rose in August to its highest level since 1990, up 16 per cent over the past year, after lamb prices hit a 37-year high, beef prices climbed to a two-year high and the cost of pork and poultry prices rose.

“There has been sustained demand from Asia and from the Middle East for both beef and lamb,” said Pedro Arias, a livestock economist at the FAO in Rome, echoing a widely held view in the industry. “But the traders have not been able to satisfy that demand because herds have been curtailed.”
