The slump in turkey sales in the wake of the outbreak of bird flu at a Bernard Matthews farm continued into its third week - but looks to have levelled off, according to Nielsen figures.

In the week ending 24 February, turkey sales were down 45% on the same period in 2006 - only marginally worse than the week ending 17 February.

But Nielsen said it believed sales to be on the rebound.

The dip was most severe in the south east of England, where sales fell 52%. Sales also fell sharply in the south west, by 49%, and in London, by 47%.
